Generally, methods of making golf club heads and golf club heads are described herein. The fabrication apparatus, methods, and articles described herein are illustrative rather than limiting.

In the example of FIGS. 1-14, the golf club head 100 includes a body portion 110 (FIG. 14) and two or more weight portions, generally a first set of weight portions 120 (Shown as portions 121, 122, 123, and 124) and a second set of weight portions 130 (shown as weight portions 131, 132, 133, 134, 135, 136, As shown in FIG. The body portion 110 may include a toe portion 140, a heel portion 150, a forward portion 160, a rear portion 170, an upper portion 180, and a bottom portion 190. The body portion 110 may be made of a first material and the first and second sets of weight portions 120 and 130 may each be made of a second material. The first and second materials may be similar or different materials. For example, the body portion 110, at least partially, steel-based material (e.g., 17-4 PH stainless steel, tronic ^® 50 stainless steel, maraging steel or any other different type of stainless steel), Titanium-based materials, aluminum-based materials (e.g., high strength aluminum alloys or composite aluminum alloys coated with high strength alloys), any combination thereof, and / or any other suitable type of materials. The first and second sets of weight portions 120 and 130 may each be made, either partially or totally, of a high-density material, such as a tungsten-based material or any other suitable type of material. Alternatively, the body portion 110 and / or the first and second sets of weight portions 120 and 130 may be made of a non-metallic material (e.g., composite, plastic, etc.), partially or entirely, respectively. The fabrication apparatus, methods, and articles are not limited to these.

The golf club head 100 may be a golf club head having an iron-type golf club head (e.g., a 1-iron, a 2-iron, a 3-iron, a 4-iron, a 5-iron, a 6- (E.g., pitching wedge, lobe wedge, sand wedge, n ° wedge, e.g., 44 °, 48 °, 52 °, 56 ° , 60 °, etc.). 1-10 illustrate certain types of clubheads, the fabrication apparatus, methods, and articles described herein may be applied to other types of clubheads (e.g., a driver-type clubhead, a fairway wood- Head, a hybrid-type club head, a putter-type club head, etc.). The fabrication apparatus, methods, and articles described herein are not limited to these.

The toe portion 140 and the heel portion 150 may be located at opposite ends of the body portion 110. [ The heel portion 150 includes a hosel portion (not shown) configured to receive a shaft (not shown) having a grip (not shown) at one end and to receive a golf club head 100 at an opposite end of the shaft 155 < / RTI >

The front portion 160 may include a face portion 162 (e.g., a striking surface). The face portion 162 may include a front surface 164 and a rear surface 166. The front surface 164 may include one or more grooves 168 extending between the toe portion 140 and the heel portion 150. Although a certain number of grooves are shown in the figures, the fabrication apparatus, methods, and articles described herein may include more or fewer grooves. Face portion 162 may be used to strike a golf ball (not shown). The face portion 162 may be an integral part of the body portion 110. Alternatively, the face portion 162 may be a separate piece, or it may be a separate piece, or it may be a separate piece or a combination of different manufacturing methods and / or processes (e.g., bonding processes such as adhesives, welding processes such as laser welding, brazing process, (not shown) coupled to the body portion 110 by a soldering process, a fusing process, a mechanical fixation or connection method, any combination thereof, or any other suitable type of manufacturing method and / ). The face portion 162 may be connected to a loft plane forming a loft angle of the golf club head 100. The loft angle may vary depending on the type of golf club (e.g., long iron, middle iron, short iron, wedge, etc.). In one example, the loft angle may be between 5 [deg.] And 75 [deg.]. In another example, the loft angle may be between 20 and 60 degrees. The fabrication apparatus, methods, and articles described herein are not limited to these.

14, the rear portion 170 includes one or more external weight ports along a periphery of the rear portion 170, generally a first set of external weight ports 1420 (e.g., (Shown as weight ports 1421, 1422, 1423, and 1424) and a second set of external weight ports 1430 (e.g., weight ports 1431, 1432, 1433, 1434, 1435, 1436, And a rear wall portion 1410 having one or more external weight ports as shown in FIG. Each external weight port can be connected to one port diameter. In one example, the port diameter may be about 0.25 inches (6.35 millimeters). Any two adjacent external weight ports of the first set of external weight ports 1420 may be located a distance less than the port diameter. Likewise, any two adjacent external weight ports of the second set of external weight ports 1430 may be located a distance less than the port diameter. The first and second external weight ports 1420 and 1430 may be external weight ports configured to receive one or more weight portions. In particular, each weight portion 120 (e.g., shown as weight portions 121, 122, 123, and 124) of the first set may be configured to include an upper portion 180 and / 140 or adjacent to or at the weight port located at the toe portion 140. For example, the weight portion 121 may be arranged in the weight port 1421, partly or wholly. In another example, the weight portion 122 is arranged in a weight port 1422 located in a transition region (e.g., an upper-to-ground transition region) between the top portion 180 and the toe portion 140 . Each weight portion 130 of the second set (shown, for example, as weight portions 131, 132, 133, 134, 135, 136, and 137) has a bottom portion 190 and / Or may be arranged in a weight port adjacent to or positioned in the toe portion 140. For example, the weight portion 135 may be arranged in the weight port 1435, partially or entirely. In another example, the weight portion 136 may be arranged in a weight port 1436 located in a transition region (e.g., bottom-to-top transition region) between the bottom portion 190 and the toe portion 140. As described in detail below, the first and second sets of weight portions 120 and 130 may each be formed by a variety of fabrication methods and / or processes (e.g., joining processes, welding processes, brazing processes, Or any suitable combination of these, or any other suitable method of manufacture and / or process) to the rear portion 170 of the body portion 110.

Alternatively, the golf club head 100 may be configured to include (i) a first set of weight portions 120, (ii) a second set of weight portions 130, or (iii) 120 and < RTI ID = 0.0 > 130). ≪ / RTI > In particular, the rear portion 170 of the body portion 110 may not include a weight port located adjacent the bottom portion 190 and / or the top portion 170 or located in the top portion 170. For example, the mass (e.g., 3 grams) of the first set of weight portions 120 and / or the mass of the second set of weight portions 130 (e.g., 16.8 grams) May be an integral body portion 110. The fabrication apparatus, methods, and articles described herein are not limited to these.

The first and second sets of weight portions 120 and 130 may each have similar or different physical properties (e.g., color, shape, size, density, mass, volume, etc.). As a result, the first and second sets of weight portions 120 and 130 can each be a factor in the ornamental design of the golf club head 100, respectively. In the example shown in FIG. 11, each of the first and second sets of weight portions 120 and 130 may each have a cylindrical shape (e.g., a circular cross-section). Alternatively, each first set of weight portions 120 may have a first shape (e.g., a cylindrical shape) and each second set of weight portions 130 may have a second shape (e.g., a cubic shape) Lt; / RTI > In another example, the first set of weight portions 120 may include two or more weight portions having different shapes (e.g., the weight portion 121 may have a first shape and the weight portion 122 may have a second form different from the first form). Similarly, the second set of weight portions 130 may include two or more weight portions having different shapes (e.g., the weight portion 131 may have a first shape and the weight portion 132 may have a second shape) May have a second form different from the first form). Although the examples describe weight portions with particular types, the fabrication apparatus, methods, and articles described herein may be used in other suitable forms (e.g., spheres, cubes, cones, cylinders, pyramids, frustum), or any other suitable geometric shape). Although the examples and figures depict a number of weight portions as a set of weight portions, each set of weight portions 120 and 130 of the first and second sets may each be an integral weight portion. In one example, the first set of weight portions 120 may be an integral weight portion instead of a series of four individual weight portions. In another example, the second set of weight portions 130 may be an integral weight portion instead of a series of seven individual weight portions. The fabrication apparatus, methods, and articles described herein are not limited to these.

12 and 13, for example, the first and second sets of weight portions 120 and 130 may each include a thread, generally designated 1210 and 1310, The thread is associated with a corresponding thread (indicated generally at 1420 and 1430 in FIG. 14) configured to secure to the weight port of the rear portion 170 within the weight port. For example, each of the weight portions of the first and second sets of weight portions 120 and 130 may each be a screw. The first and second sets of weight portions 120 and 130 may not be easily removed from the body portion 110 with or without a tool, respectively. Alternatively, the first and second sets of weight portions 120 and 130 may each be easily removed (e.g., using a tool) such that a relatively heavy or lightweight portion of the weight can be removed from the first and second sets of One or more weight portions 120 and 130 may be substituted. In another example, the first and second set of weight portions 120 and 130 may each have a first and a second set of weight portions 120 and 130, respectively, May be fixed to the weight port of portion 170. In yet another example, the first and second set of weight portions 120 and 130 may each include an epoxy and a threaded rear portion 170 (not shown) such that the first and second sets of weight portions 120 and 130 are not easily removed, As shown in FIG. The fabrication apparatus, methods, and articles described herein are not limited to these.

As noted above, the first and second sets of weight portions 120 and 130, respectively, may have some similar physical properties but may be different in other physical properties. As illustrated in FIGS. 11-13, for example, each of the weight portions 120 and 130 of the first and second sets may have a diameter 1110 of about 0.25 inches (6.35 millimeters), respectively , The first and second sets of weight portions 120 and 130 may each have a different height. In particular, each weight portion 120 of the first set may have a first height 1220 (FIG. 12), and each weight portion 130 of the second set may have a second height 1320 ). The first height 1220 may be relatively shorter than the second height 1320. In one example, the first height 1220 can be about 0.125 inches (3.175 millimeters) and the second height 1320 can be about 0.3 inches (7.62 millimeters). In another example, the first height 1220 may be about 0.16 inches and the second height 1320 may be about 0.4 inches (10.16 millimeters). Alternatively, the first height 1220 may be equal to or greater than the second height 1320. The fabrication apparatus, methods, and articles described herein are not limited to these.

10, for example, the golf club head 100 may be associated with the ground 1010, the horizontal center plane 1020, and the upper plane 1030. In particular, the ground plane 1010 is positioned at the bottom of the golf club head 100 (e.g., when the golf club head 100 is aligned to strike the golf ball) when the golf club head 100 is in the addressed position (Tangential plane) to the tangential plane. The upper plane 1030 may be a tangential plane to the upper portion 180 of the golf club head 100 when the golf club head 100 is in the addressed position. The ground and upper planes 1010 and 1030, respectively, may be substantially parallel to one another. The horizontal centerplane 1020 may be arranged in an intermediate position between the ground and the upper planes 1010 and 1030, respectively, in the vertical direction.

The weight portions 120 (e.g., weight portions 121, 122, 123, and 124) of the first set may be configured to provide optimal perimeter weighting for the golf club head 100, ) To balance the weight of the patient. 10, a first set of weight portions 120 (e.g., weight portions 121, 122, 123, and 124) may be positioned near the periphery of body portion 110 May extend from the upper portion to the transition region 145 between the upper portion 180 and the toe portion 140 and extend from the transition region 145 to the toe portion 140. In other words, the first set of weight portions 120 may be arranged on the golf club head 100 generally at a position opposite to the hosel 155. According to one example, at least a portion of the first set of weight portions 120 may be located near the periphery of the body portion 110 and may extend through the transition region 145. According to another example, at least a portion of the first set of weight portions 120 may extend near the periphery of the body portion 110 and extend along a portion of the upper portion 180. According to another example, at least a portion of the first set of weight portions 120 may extend near the periphery of the body portion 110 and extend along a portion of the toe portion 140. The first set of weight portions 120 may be arranged on the horizontal center plane 1020 of the golf club head 100. At least a portion of the first set of weight portions 120 is positioned proximate to the toe portion 140 so that the golf club head 100 extends about the vertical axis of the golf club head 100, 100 can be increased. The first set of weight portions 120 can be positioned near the periphery of the body portion 110 and extend through the upper portion 180, the toe portion 140, and / or the transition region 145, Or to balance the weight of the golf club head 155 and / or to increase the moment of inertia of the golf club head 100. The material and physical properties of the components of the first set of weight portions 120 (i.e., the positions of the first set of external weight ports 1420) and the weight portions of the first set of weight portions 120, Weight distribution, gravity center, moment of inertia characteristic, structural integrity, and / or other static and / or dynamic properties of the apparatus 100 of the present invention. The fabrication apparatus, methods, and articles described herein are not limited to these.

A second set of weight portions 130 (e.g., weight portions 131, 132, 133, 134, 135, 136, and 137) align the center of gravity of the golf club head 100 in an optimal position, May be configured to optimize the moment of inertia of the golf club head about a vertical axis extending through the center of gravity of the golf club head (100). 10, all or a substantial portion of the second set of weight portions 130 may generally be located closer to the bottom portion 190. [ For example, a second set of weight portions 130 (e.g., weight portions 131,133, 134,135, 136, and 137) are arranged near the perimeter of the body portion 110, 190 to the toe portion 140. As shown in the example of Figure 10, the weight portions 131, 132, 133, and 134 may be located near the periphery of the body portion 110 and extend along the bottom portion 190, ) Can be lowered. The weight portions 135,136 and 137 may be located near the periphery of the body portion 110 and may extend from the bottom portion 190 through the transition region 147 between the bottom portion 190 and the toe 140, Portion 140 to lower the center of gravity of the golf club head 100 and increase the moment of inertia of the golf club head 100 about a vertical axis extending through the center of gravity. All or a portion of the second set of weight portions 130 may be positioned closer to the bottom portion 190 than the horizontal center plane 1020 to lower the center of gravity of the golf club head 100. For example, the weight portions 131, 132, 133, 134, 135, and 136 may be positioned closer to the bottom portion 190 than the horizontal centerplane 1020. The material and physical properties of the components of the second set of weight portions 130 (i.e., the positions of the second set of external weight ports 1430) and the weight portions of the second set of weight portions 130, Weight distribution, gravity center, moment of inertia characteristic, structural integrity, and / or other static and / or dynamic properties of the apparatus 100 in accordance with the present invention. The fabrication apparatus, methods, and articles described herein are not limited to these.

7-9, for example, the first and second sets of weight portions 120 and 130 may be positioned away from the rear surface 166 of the face portion 162 (e.g., Lt; / RTI > This means that each of the first and second sets of weight portions 120 and 130 and the rear surface 166 can be located at least partly by the inner cavity 700 of the body portion 110, . As shown in Figure 14, for example, each of the external weight ports of the first and second sets of external weight ports 1420 and 1430 may have an opening (e.g., generally indicated at 720 and 730) And port walls (e.g., generally designated by reference numerals 725 and 735). The port walls 725 and 735 may be integral portions of the rear wall portion 1410 (e.g., a section of the rear wall portion 1410). Each of the openings 720 and 730 may be configured to receive a weight portion, e.g., a respective weight portion 121 and 135. The opening 720 can be located at one end of the weight port 1421 and the port wall 725 can be located at the opposite end of the weight port 1421 or close to the opposite end. Similarly, the opening 730 may be located at one end of the weight port 1435 and the port wall 735 may be located at the opposite end of the weight port 1435 or close to the opposite end thereof . Port walls 725 and 735 may be positioned away from face portion 162 (e.g., may be located apart by inner cavity 700). The port wall 725 may have a distance 726 from the rear surface 166 of the face portion 162, as shown in FIG. The port wall 735 may have a distance 736 from the rear surface 166 of the face portion 162. The distances 726 and 736 are such that the first and second sets of weight ports 1420 and 1430 are positioned at the center of gravity of the golf club head 100 when receiving weight portions such as those described herein, . ≪ / RTI > According to one example, distance 736 is greater than distance 726 so that the center of gravity of golf club head 100 can be moved toward rear portion 170. As a result, the width 740 of a portion of the inner cavity 700 below the horizontal center plane 1020 may be greater than the width 742 of the inner cavity 700 on the horizontal center plane 1020. The fabrication apparatus, methods, and articles described herein are not limited to these.

As discussed herein, the center of gravity CG of the golf club head 100 may be relatively far from the face portion 162 and may be spaced apart from the ground (e.g., indicated at 1010 in FIG. 10) The entire or substantial portion of the second set of weight portions 130 is positioned closer to the bottom portion 190 than the horizontal centerplane 1020 and the first and second sets of weights 130, Portions 120 and 130 are each located further away from the rear surface 166 than when the second set of weight portions 130 are joined directly to the rear surface 166.

In one example, the weight ports of the first and / or second set of weight ports 1420 and 1430 may have a U-shaped cross-sectional shape. In another example, the weight ports of the first and / or second set of weight ports 1420 and 1430 may have a V-shaped cross-sectional shape. One or more of the weight ports of the first set of weight portions 120 may have a different cross-sectional shape than the one or more of the weight ports of the second set of weight portions 130. For example, the weight port 1421 may have a U-shaped cross-sectional shape and the weight port 1435 may have a V-shaped cross-sectional shape. Additionally, two or more weight ports of the first set of weight portions 120 may have different cross-sectional shapes. Similarly, two or more weight ports of the second set of weight portions 130 may have different cross-sectional shapes. The fabrication apparatus, methods, and articles described herein are not limited to these.

The weight portions 120 and 130 of the first and second sets may each be similar in mass (e.g., the weight of all weight portions 120 and 130 in the first and second sets are approximately the same). Alternatively, the weight portions 120 and 130 of the first and second sets may each be different in mass, individually or as a whole. In particular, each weight portion 120 (e.g., shown at 121, 122, 123, and 124) of the first set may include a second set of optional weight portions 130 (e.g., 131, 132, 133, 134, 135, 136, and 137). For example, the second set of weight portions 130 may be greater than 50% of the total mass from the outer weight portion of the golf club head 100. As a result, the golf club head 100 may be configured to have at least 50% of the total mass from the outer weight portion arranged below the horizontal midplane 1020. The fabrication apparatus, methods, and articles described herein are not limited to these.

In one example, the golf club head 100 may have a mass in the range of about 220 grams to about 330 grams, depending on the type of golf club (e.g., 4-iron vs. lobe wedge). The body portion 110 may have a mass ranging from about 200 grams to about 310 grams and the first and second sets of weight portions 120 and 130 may each have a mass of about 20 grams Total mass from the portions). Each weight portion 120 of the first set may have a mass of about one gram (1.0 g) and each weight portion 130 of the second set may have a mass of about 2.4 grams. The sum of the masses of the first set of weight portions 120 can be about 3 grams and the sum of the masses of the second set of weight portions 130 can be about 16.8 grams. The total mass of the second set of weight portions 130 may be greater than five times the total mass of the first set of weight portions 120 (e.g., about 16.8 grams of the second set of weight portions 130) The total mass of the first set of weight portions 120 of about 3 grams total mass). The golf club head 100 has a total mass of 19.8 grams (e.g., 3 grams from the first set of weight portions 120 and a second set of weights 120 and 130, respectively) from the first and second set of weight portions 120 and 130, A sum of 16.8 grams from portion 130). Accordingly, the first set of weight portions 120 may have about 15% of the total mass from the outer weight portion of the golf club head 100, and the second set of weight portions 130 may have a length 0.0 > 85% < / RTI > The fabrication apparatus, methods, and articles described herein are not limited to these.

The first and second sets of weight portions 120 and 130 may be coupled to the body portion 110 respectively (e.g., by connecting the first and second sets of weight portions 120 and 130 to the rear portion 170) The position of the center of gravity CG and the moment of inertia MOI of the golf club head 100 can be optimized. In particular, as described herein, the first and second sets of weight portions 120 and 130 may each cause the position of the center of gravity CG to point down toward the bottom portion 190, Away from the face portion 162. In addition, the moment of inertia MOI may be as large as measured about a vertical axis extending through the center of gravity CG (e.g., perpendicular to the ground 1010). In addition, the moment of inertia (MOI) is defined as the moment of inertia (MOI), as measured about a horizontal axis extending through the center of gravity CG (e.g., extending toward the sole portion of the golf club head 100 and toward the heel portions 150 and 160) . As a result, the club head 100 has a relatively larger launch angle than the golf club head without the respective first and second set of weight portions 120 and 130, rate. The fabrication apparatus, methods, and articles described herein are not limited to these.

Alternatively, two or more weight portions of the same set may be different in mass. In one example, the weight portion 121 of the first set 120 may have a relatively smaller mass than the weight portion 122 of the first set 120. In yet another example, the weight portion 131 of the second set 130 may have a relatively smaller mass than the weight portion 135 of the second set 130. Since a relatively large mass is provided in the top-to-bottom transition region and / or the bottom-to-top transition region, a greater weight is distributed away from the center of gravity CG of the golf club head 100, The moment of inertia (MOI) around the passing vertical axis is increased.

Although the weight portions are shown as being spaced apart and shown as separate portions in the figures, the first and second sets of weight portions 120 and 130 of each set may each be an integral portion of the weight portion. In one example, all weight portions 120 (e.g., designated 121, 122, 123, and 124) of the first set can be combined into an integral portion (e.g., a first weight portion) have. Similarly, all of the weight portions 130 of the second set (denoted by reference numerals 131, 132, 133, 134, 135, 136, and 137) may have an integral portion of the weight portion ). ≪ / RTI > In this example, the golf club head 100 may have only two weight portions. Although a certain number of weight portions are shown in the figures, the fabrication apparatus, methods, and articles described herein may include more or fewer weight portions. In one example, the first set of weight portions 120 may include two individual weight portions instead of three individual weight portions as shown in the figures. In another example, the second set of weight portions 130 may include five individual weight portions instead of seven individual weight portions as shown in the figures. Alternatively, as noted above, the fabrication apparatus, methods, and articles described herein may not include any discrete weight portions (e.g., the body portion 110 may include an integral portion of the body portion 110) (S) to include the mass of the individual weight portions). The fabrication apparatus, methods, and articles described herein are not limited to these.

7-9, for example, the body portion 110 may be a hollow body that includes an inner cavity 700 extending between the forward portion 160 and the rear portion 170. [ have. In addition, the inner cavity 700 may extend between the upper portion 180 and the lower portion 190. The inner cavity 700 may be associated with a cavity height 750 (H _C ) and the body portion 110 may be associated with a body height 850 (H _B ). Cavity height (750) and the body height 850 may be changed between the soil portion and a heel portion 140 and 150 are tied high (750) may be at least 50% of the body height 850 (H _C > 0.5 * H _B ). For example, the cavity height 750 may vary between 70-85% of the body height 850. When the golf club head 100 hits the golf ball by the face portion 162, if the cavity height 750 of the inner cavity 700 is greater than 50% of the body height 850, The golf club head 100 may produce a relatively more consistent tactile, sound, and / or result, as compared to the case where the golf club head 100 is at a cavity height of less than 50% of the height. The fabrication apparatus, methods, and articles described herein are not limited to these.

In one example, the inner cavity 700 may not be filled (i.e., it may be hollow). The body portion 100 with the inner cavity 700 may have a weight of about 100 grams less than the body portion 100 without the inner cavity 700. In the alternative, the interior cavity 700, at least partially, the elastic polymer or elastomer material (e.g., viscoelastic polyurethane polymer material, for example, the United States, OH, located in Kent City Sober X Saga produced Sober X ^® materials), thermoplastic (TPE), thermoplastic polyurethane material (TPU), and / or any other suitable type of material to absorb shock, isolate vibration, and / or attenuate noise. For example, at least 50% of the internal cavity 700 may be configured to absorb impact, separate vibration, and / or noise when the golf club head 100 hits the golf ball with the face portion 162 RTI ID = 0.0 > TPE < / RTI >

In another example, the inner cavity 700 may be configured to partially or wholly absorb the impact, separate the vibrations, and / or move the ball when the golf club head 100 hits the golf ball with the face portion 162. [ Or may be filled with a polymer material, such as an ethylene copolymer material, to attenuate noise. In particular, at least 50% of the internal cavity 700 comprises a high density ethylene copolymer ionomer, a fatty acid modified ethylene copolymer ionomer, a high amorphous ethylene copolymer ionomer, an ionomer of an ethylene acid acrylate terpolymer, an ethylene copolymer comprising a magnesium ionomer , Injection moldable ethylene copolymers that can be used in conventional injection molding apparatus to form various shapes, ethylene copolymers that can be used in conventional extrusion apparatus to form various shapes, and / or thermosetting polybutadiene rubbers Can be filled with an ethylene copolymer having high compressibility and low elasticity. For example, ethylene copolymers can be made from any of the ethylene copolymers associated with the DuPont ™ high-performance resin (HPF) material family (eg DuPont ™ HPF AD1172, DuPont ™ HPF AD1035, DuPont® HPF 1000 and DuPont ™ HPF 2000) Which is manufactured by DuPont in Wilmington, Delaware, USA. The DuPont (TM) HPF ethylene copolymer family can be injection molded and used with conventional injection molding apparatus and molds to provide low compressibility and high resilience. The fabrication apparatus, methods, and articles described herein are not limited to these.

15, for example, the face portion 162 may include a first thickness 1510 (T ₁ ) and a second thickness 1520 (T ₂ ). The first thickness 1510 may be the thickness of one section of the face portion 162 adjacent the groove 168 and the second thickness 1520 may be the thickness of one section of the face portion 162 below the groove 168 Lt; / RTI > For example, the first thickness 1510 may be the maximum distance between the front surface 164 and the rear surface 166. The second thickness 1520 may depend on the groove 168. In particular, the groove 168 may have a groove depth 1525 (D- _groove ). The second thickness 1520 may be the maximum distance between the rear surface 166 and the bottom of the groove 168. The sum of the second thickness 1520 and the groove depth 1525 may be substantially equal to the first thickness 1510 (e.g., T ₂ + D _groove = T ₁ ). Accordingly, the second thickness 1520 may be less than the first thickness 1510 (e.g., T ₂ < T ₁ ).

The weight from the front portion 160 of the golf club head 100 is reduced by using a relatively thin face portion 162 to lower and / or move the center of gravity CG of the golf club head 100 Can be removed. For example, the first thickness 1510 can be about 0.075 inches (e.g., 1.905 millimeters) (e.g., T ₁ = 0.075 inches). Supporting the rear wall portion 1410 to form the inner cavity 700 and filling at least a portion of the inner cavity 700 with an elastomeric polymeric material provides structural integrity, sound, and / The face portion 162 can be relatively thin (e.g., T ₁ < In one example, the first thickness 1510 may be less than or equal to 0.060 inches (1.524 millimeters) (e.g., T1? 0.060 inches). In another example, the first thickness 1510 may be less than or equal to 0.040 inches (e.g., T ₁ 0.040 inches). Depending on the type of material (s) used to form the body portion 110 and / or the face portion 162, the face portion 162 may be even thinner such that the first thickness 1510 is 0.030 inches (0.762 millimeters) (E.g., T ₁ 0.030 inches). The groove depth 1525 may be greater than or equal to the second thickness 1520 (e.g., D- _groove ≥ T ₂ ). In one example, the groove depth 1525 can be about 0.020 inches (0.508 mm) (e.g., D- _groove = 0.020 inches). Accordingly, the second thickness 1520 can be about 0.010 inches (0.254 millimeters) (e.g., T ₂ = 0.010 inches). In another example, the groove depth 1525 can be about 0.015 inches (0.381 mm) and the second thickness 1520 can be about 0.015 inches (e.g., D- _groove = T ₂ = 0.015 inches). Alternatively, the groove depth 1525 may be less than the second thickness 1520 (e.g., D- _home < T ₂ ). If the rear wall portion 1410 is not supported and the inner cavity 700 is not filled with elastic polymer material, the golf club head will be hit several times by the golf ball and will not be able to withstand the impact provided to the face portion. A golf club head 100 having a relatively thin face portion but no back wall portion 1410 and an inner cavity 700 filled with an elastomeric polymer material (e.g., , Co-rear golf club head) may be formed with unpleasant tactile sensation and / or uncomfortable sound (e.g., iron hitting sound) when hitting the golf ball. The fabrication apparatus, methods, and articles described herein are not limited to these.

Depending on the fabrication process and methods used to form the golf club head 100, the face portion 162 may include additional material near the face portion 162 or proximate the periphery of the face portion 162 . Accordingly, the face portion 162 may include a third thickness 1530, and a chamfer portion 1540. The third thickness 1530 may be greater than the first thickness 1510 or the second thickness 1520 (e.g., T ₃ > T ₁ > T ₂ ). In particular, the face portion 162 may be joined to the body portion 110 by a welding process. For example, the first thickness 1510 may be about 0.030 inches, the second thickness 1520 may be about 0.015 inches (0.381 millimeters), the third thickness may be about 0.050 inches (1.27 millimeters) ). As such, the chamfer portion 1540 may accommodate some additional material when the face portion 162 is welded to the body portion 110.

As illustrated in FIG. 16, for example, the face portion 162 may include a reinforcement section generally indicated at 1605 below one or more grooves 168. In one example, the face portion 162 may include a reinforcement section 1605 under each groove. Alternatively, the face portion 162 may include a reinforcement section 1605 beneath some grooves (e. G., By sifting a groove) or only under one groove. The face portion 162 may include a first thickness 1610, a second thickness 1620, a third thickness 1630, and a chamfer portion 1640. The groove 168 may have a groove depth 1625. The reinforcing section 168 may form a second thickness 1620. [ The first and second thicknesses 1610 and 1620 may each be substantially equal to each other (e.g., T ₁ = T ₂ ). In one example, the first and second thicknesses 1610 and 1620 may be about 0.030 inches (0.762 millimeters) (e.g., T ₁ = T ₂ = 0.030 inches), respectively. The groove depth 1625 may be about 0.015 inches (0.381 mm), and the third thickness 1630 may be about 0.050 inches (1.27 mm). In addition, the groove 168 may have a groove width. The width of the reinforcing section 1605 may be greater than or equal to the groove width. The fabrication apparatus, methods, and articles described herein are not limited to these.

Alternatively, the face portion 162 may vary in thickness at and / or between the upper portion 180 and the lower portion 190. In one example, the face portion 162 may be relatively thick at the top portion 180 or at a location proximate to the top portion 180 than at the bottom portion 190 or near the bottom portion 190 For example, the thickness of the face portion 162 may be tapered from the upper portion 180 toward the lower portion 190). In another example, the face portion 162 may be relatively thicker at the top portion 180 or at a location closer to the bottom portion 190 or at the bottom portion 190 than at a location proximate to the top portion 180 (E.g., the thickness of the face portion 162 may be tapered from the bottom portion 190 toward the top portion 180). In another example, the face portion 162 may be positioned in the upper portion 180 and the lower portion 190, or in a position closer to the upper portion 180 and the lower portion 190 than the upper portion 180 and the lower portion 190 (E.g., the thickness of the face portion 162 may have a bell-shaped contour). The fabrication apparatus, methods, and articles described herein are not limited to these.

Due to the position of the inner cavity 700 of the body portion 110 and the first and second sets of weight portions 120 and 130, unlike other golf club head designs, the periphery of the golf club head 100 The golf ball will move from the face portion 162 at a relatively higher ball throw angle and at a relatively low rotational speed. As a result, the golf ball can move farther (i.e., the total distance including the carry distance and the roll distance can be larger).

17 is a diagram illustrating a method by which the golf club head example described herein can be made. In the example of Figure 17, the process 1700 generally includes providing two or more weight portions, shown as weight portions 120 and 130, respectively, of the first and second sets (Step 1710) Can be started. The first and second sets of weight portions 120 and 130 may each be made of a first material, such as a tungsten-based material. In one example, the first and second sets of weight portions 120 and 130 may each be a tungsten-alloy screw.

The process 1700 includes a back portion 170 having two or more external weight ports generally designated 1420 and 1430, an internal cavity 700, and a body portion 110 having a face portion 162 (Step 1720). The body portion 110 may be made of a second material different from the first material. The body portion 110 may be formed by any suitable process known in the art such as an investment casting process, a billet forging process, a stamping process, a computer numerical control (CNC) machining process, a die casting process, Any combination thereof, or any other suitable manufacturing process. In one example, the body portion 110 may be made of 17-4 PH stainless steel using a casting process. Also made in another example, the body portion 110 by using a forging process, and other stainless steel of suitable types (e.g., United States, Ohio, West Chester when, AK steel kopeoreyisyeonsa the one you tronic ^® 50 Stainless Steel, Ltd.) . In order to produce the body portion 110. Needle tronic ^® 50 stainless steel by using a steel golf club head 100 Gini a more durable against corrosion as compared to the golf club head made of steel or other types and / or It can be relatively strong. Each weight port of the body portion 110 may include an opening and a port wall. For example, the weight port 1421 can include an opening 720 and a port wall 725, wherein the opening 720 and the port wall 725 can be located at opposite ends. The inner cavity 700 can separate the rear surface 166 of the face portion 162 and the port wall 725 of the weight port 1421. Similarly, the weight port 1835 can include an opening 730 and a port wall 735, wherein the opening 730 and the port wall 745 can be located at opposite ends. The inner cavity 700 can separate the rear surface 166 of the face portion 162 and the port wall 735 of the weight port 1435.

The process 1700 may couple each of the first and second sets of weight portions 120 and 130 to one of two or more external weight ports (step 1730). In one example, the process 1700 can insert and fix the weight portion 121 into the external weight port 1421 and insert and fix the weight portion 135 into the external weight portion 1435. The process 1700 can be performed using a variety of fabrication methods and / or processes (e.g., epoxy, welding, soldering, mechanical fixation, any combination thereof, 130 to the external weight ports, e.g., the weight ports 1421 and 1435. [

Step 1700, fills at least partially, inside the cavity of an elastic polymer material (e. G., Sober X ^® materials) or polymeric materials (e.g., ethylene copolymer material, for example, DuPont ™ HPF material group) 700 ( Step 1740). In one example, at least 50% of the inner cavity 700 may be filled with an elastomeric polymer material. As mentioned above, the elastomeric polymer material can absorb impact, separate vibration, and / or attenuate noise corresponding to the golf club head 100 striking the golf ball. Alternatively or alternatively, the inner cavity 700 may be filled with a thermoplastic elastomeric material and / or a thermoplastic polyurethane material. 18, for example, the golf club head 100 may include one or more weight ports (e.g., 1431 in Fig. 14) having a first opening 1830 and a second opening 1835 )). &Lt; / RTI &gt; The second opening 1835 can be used to access the inner cavity 700. In one example, the process 1700 (FIG. 17) includes injecting elastic polymer material from the first opening 1830 into the inner cavity 700 through the second opening 1835, ). Each of the first and second openings 1830 and 1835 may be the same or different in size and / or shape. Any other weight port (e.g., weight port 720) of the golf club head 100 may include a second opening, although the example describes and depicts a particular weight port with a second opening. The fabrication apparatus, methods, and articles described herein are not limited to these.

Referring again to FIG. 17, as an example of one method of making golf club head 100, process 1700 is provided and described with other figures. In FIG. 17, steps of a particular sequence are illustrated, but these steps may also be performed in other time sequences. For example, the two or more steps shown in FIG. 17 may be performed sequentially, concurrently, or concurrently. In one example, steps 1710, 1720, 1730, and / or 1740 may be performed simultaneously or may be performed together. Although Figure 17 illustrates a certain number of steps, the process may not be performed in one or more steps. In one example, the inner cavity 700 may not be filled (i.e., step 1740 may not be performed). The fabrication apparatus, methods, and articles described herein are not limited to these.

Referring again to Figures 1-14, the face portion 162 may be used to relieve delamination between the elastic polymeric material used to fill the inner cavity 700 and the face portion 162 and / (E.g., Fig. 7). In order to form the rear surface 166 within the non-smooth surface, various methods and / or processes, such as abrasive blasting processes (e.g., bead blasting process, sandblasting process, other suitable blasting process, ) And / or milling (machining) processes may be used. For example, the back surface 166 may have a surface roughness (Ra) between 0.5 and 250 microinches (0.012 to 6.3 micrometers). The fabrication apparatus, methods, and articles described herein are not limited to these.

As illustrated in FIGS. 19-21, for example, the face portion 1900 may include a front surface 1910, and a rear surface 2010. The front surface 1910 can include one or more grooves, generally designated 1920, which extend longitudinally across the front surface 1910 (e.g., 1 between the heel portion 150 and the toe portion 140). The front surface 1910 can be used to strike a golf ball (not shown).

In addition, the rear surface 2010 may include one or more channels, generally indicated by the reference numeral 2020. The channel 2020 may extend longitudinally across the rear surface 2010. The channels 2020 may be arranged parallel to each other or substantially parallel to each other. The channel 2020 can be combined with the elastic polymer material used to fill the inner cavity 700 and can be used as a mechanical locking mechanism between the elastic polymer material and the face portion 1900. In particular, the channel 2100 can include two sidewalls, shown as openings 2110, bottom sections 2120, and generally 2130 and 2132. The bottom section 2120 may be arranged parallel or substantially parallel to the rear surface 2010. The two side walls 2130 and 2132 may be a converging sidewall (i.e., the two side walls 2130 and 2132 may not be parallel to each other). The bottom section 2120 and the side walls 2130 and 2132 may form two undercut portions, generally designated 2140 and 2142. This means that the width 2115 in the opening 2110 may be less than the width 2125 of the bottom section 2120. The cross-section of the channel 2100 may be symmetrical about an axis 2150. 21 shows a flat or substantially flat side wall, the two side walls 2130 and 2132 may be curved (e.g., they may be formed to be convex).

Instead of a flat or substantially flat sidewall as shown in Fig. 21, the channel may also include other types of sidewalls. As illustrated in FIG. 22, for example, channel 2200 may include two sidewalls, shown as openings 2210, bottom sections 2220, and generally 2230 and 2232. The bottom section 2220 may be arranged parallel or substantially parallel to the rear surface 2010. The two side walls 2230 and 2232 may be stepped side walls. The bottom section 2220 and the side walls 2230 and 2232 can form two undercut portions, generally designated 2240 and 2242. This means that the width 2215 in the opening 2210 may be smaller than the width 2225 of the bottom section 2220. The cross-section of the channel 2200 may be symmetrical about an axis 2250.

Instead of being symmetrical as shown in FIGS. 21 and 22, the channel may be asymmetric. As illustrated in Figure 23, as another example, the channel 2300 can include two sidewalls, shown as openings 2310, bottom sections 2320, and generally 2330 and 2332 . The bottom section 2320 may be arranged parallel or substantially parallel to the rear surface 2010. The bottom section 2320 and the side wall 2330 may form an undercut portion 2340.

24, for example, channel 2400 may include two sidewalls, shown as openings 2410, bottom sections 2420, and generally 2430 and 2432. [ The bottom section 2420 may be arranged so as not to be parallel or substantiallyparallel to the rear surface 2010. The two sidewalls 2430 and 2432 may be arranged parallel or substantially parallel to each other, but one sidewall may be longer than the other sidewall. The bottom section 2420 and side wall 2432 can form an undercut section 2440.

25, the face portion 2500 may include a rear surface 2510 having one or more channels generally designated by the reference numeral 2520, which may include one or more channels 2520, (E.g., extending between the bottom portion 190 and the top portion 180 of FIG. 1) across the rear surface 2510. 26, the face portion 2600 can include a rear surface 2610 having one or more channels generally designated by the numeral 2620, and the one or more channels 2610, (2620) extends diagonally across the rear surface (2610). Alternatively, the face portion may include a combination of channels extending in different directions (e.g., longitudinally, transversely, and / or diagonally extending) across the rear surface of the face portion. 27, the face portion 2700 may include a rear surface 2710 having one or more channels generally designated 2720, 2730, and 2740, One or more of the channels extend in a different direction across the rear surface 2710. In particular, the face portion 2700 includes a plurality of channels 2720 extending longitudinally across the rear surface 2710, a plurality of channels 2730 extending transversely across the rear surface 2710, And may include a plurality of channels 2740 that extend diagonally across the surface 2710.

Alternatively or in the alternative, the golf club head 100 may be configured to mitigate and / or alleviate delamination between the elastic polymeric material used to fill the inner cavity 700 of the golf club head 100 and the face portion 162. [ (E. G., FIG. 7). &Lt; / RTI &gt; 28, for example, the golf club head 100 may include a face portion 162, a mating portion 2810, and an elastomeric polymeric material 2820. In one example, the bonding portion 2810 can be a low-viscosity, organic, solvent-based solution and / or dispersed polymer and other reactive chemicals such as MEGUM ™ manufactured by Dow Chemical Company located in Auburn Hills, Mich., ROBOND , &Lt; / RTI &gt; and / or THIXON (TM) materials. In another example, bonding portion 2810 may be a LOCTITE® material manufactured by Henkel Corporation located in Rocky Hill, Conn. The engagement portion 2810 may be provided on the rear surface 166 to couple the elastic polymeric material 2820 to the face portion 162 (e.g., extending between the back surface 166 and the elastic polymeric material 2820) ). For example, engagement portion 2810 may be provided when inner cavity 700 is filled with elastomeric polymer material 2820 by an injection molding process. The fabrication apparatus, methods, and articles described herein are not limited to these.

Figure 29 illustrates how the golf club head 100 or the inner cavity 700 of any golf club head described herein is partially or fully filled with an elastomeric or elastomeric material. The process 2900 may begin with heating the golf club head 100 to a specific temperature (step 2910). In one example, the golf club head 100 may be heated to a temperature between 150 ° C and 250 ° C, which may be dependent on factors such as the evaporation temperature of the elastomeric polymer material to be injected into the inner cavity 700 . The elastomeric polymer material can then be heated to a specified temperature (step 2920). The elastomeric polymer material may be a non-foamable and injection-molded thermoplastic elastomer (TPE) material. Accordingly, the elastomeric polymer material may be heated to reach a liquid or flow state before being injected into the inner cavity 700. The temperature at which the elastomeric polymer material can be heated may depend on the type of elastomeric polymer material used to partially or wholly fill the inner cavity 700. The heated elastomeric polymer material may be injected into the inner cavity 700 to fill the inner cavity 700 partially or wholly (step 2930). The elastomeric polymeric material may include one or more of the weight ports described herein (e.g., one or more of the first and second set of weight ports 1420 and 1430, as shown in Figure 14) Weight port) into the inner cavity 700. One or more other weight ports allow air to be vented from the inner cavity 700 by the elastic polymer material within the inner cavity 700. In one example, the golf club head 100 may be arranged in the horizontal direction as shown in FIG. 14 during the injection molding process. Elastic polymer material may be injected into the inner cavity 700 from the weight ports 1431 and 1432. The weight ports 1421, 1422 and / or 1423 may be used as an air port for venting the moved air from the inner cavity 700. Thus, during the injection molding process, irrespective of the orientation of the golf club head 100, the elastomeric polymer material can be injected into the inner cavity 700 from one or more lower positioned weight ports, May be used as an air vent. The mold (i. E., The golf club head 100) may be cooled in a passive manner (e. G., At room temperature) or in an active manner such that the elastomeric polymer material reaches a solid state and the rear surface of the face portion 162 166, respectively. The elastic polymer material may be attached directly to the back surface 166 of the face portion 162. Alternatively, the elastomeric polymer material may be applied to the face portion 162 (e.g., with the aid of a binder and / or one or more structures on the back surface 166, such as the engagement portion 2810 shown in FIG. 28) To the rear surface 166 of the base plate. The fabrication apparatus, methods, and articles described herein are not limited to these.

As discussed above, the elastomeric polymer material can be heated to a liquid state (i.e., non-foamable) and is injection molded in the inner cavity 700 and then hardened. Elastic polymeric materials with low modulus of elasticity can provide vibration and noise attenuation for the face portion 162 when the face portion 162 strikes the golf ball. For example, an elastomeric polymer material that is foamed when heated can provide vibration and noise attenuation. However, such foamed elastomeric polymeric material has sufficient stiffness to provide structural support to the relatively thin face portion, due to the possibility of shrinkage and / or excessive deflection of the elastomeric polymeric material when absorbing the impact of the golf ball You may not have. In one example, the resilient polymeric material injection molded in the inner cavity 700 has a relatively high modulus of elasticity to provide structural support to the face portion 162, but may be provided by the face portion 162, It may be biased elastically to absorb an impact force. Thus, in order to provide structural support and reinforcement for the face portion 162, in addition to filling the inner cavity 700, partially or wholly, and providing vibration and noise damping, non-foamable and non- A forming elastic polymer material can be used. This means that non-foamable and injection-molded elastic polymeric materials can be used for the structural support portion for the face portion 162. The fabrication apparatus, methods, and articles described herein are not limited to these.

Figure 30 illustrates a method as long as the bonding agent can be provided to the golf club head before partially or fully injecting the elastic polymer into the inner cavity 700, as described herein. In the example of FIG. 30, the process 3000 may begin with the step of injecting a binder onto the rear surface 166 of the face portion 162 (step 3010). The binder may be injected into the rear surface 166, either before or after heating the golf club head, as described above, depending on the nature of the binder. The binder may be injected through one or more of the first set of weight ports 1420 and / or the second set of weight ports 1430. The binder may be injected into the rear surface 166 through all or some of the weight ports of the first set of weight ports 1420 and the second set of weight ports 1430. [ For example, an infusion device, such as a nozzle or a needle, may be inserted into each weight port until the end or outlet of the infusion device is positioned near the rear surface 166. The binder may then be injected into the rear surface 166 from the outlet of the injection device. The injection device may also be moved, rotated and / or swiveled to be injected into the region of the rear surface 166 surrounding the injection device when arranged in the inner cavity 700. For example, the outlet of the injection device can be moved in a circular pattern, and when in the weight port, the coupling arrangement can be injected into the rear surface 166 in a corresponding circular pattern. Each first set of weight ports 1420 and a second set of weight ports 1430 can be used to inject a binder into the rear surface 166. However, it may not be necessary to use the first set of weight ports 1420 and / or the second set of weight ports 1430 all at once. For example, one additional weight port of adjacent weight ports may also be sufficient to inject the bonding agent over the entire rear surface 166. In another example, the weight ports 1421, 1422, 1431, 1433, and 1436 may be used to inject the bonding agent into the rear surface 166. [ The fabrication apparatus, methods, and articles described herein are not limited to these.

The process 3000 also includes a step of spreading the binder onto the back surface 166 so that the binder is generally uniformly coated on the back surface 166 after the binder has been injected into the back surface 166 (Step 3020). According to one example, by injecting air into the inner cavity 700 through one or more of the first set of weight ports 1420 and the second set of weight ports 1430, ). &Lt; / RTI &gt; Air can be introduced into the rear surface 166 and the inner cavity 700 by inserting an air nozzle into one or more of the first set of weight ports 1420 and the second set of weight ports 1430. [ ). &Lt; / RTI &gt; According to one example, the air nozzle may be configured to blow air uniformly onto the backing surface 166, such that air can be uniformly sprayed to the backing surface 166, or even uniformly coated, May be moved a certain distance, rotated, and / or swiveled from the rear surface 166. The fabrication apparatus, methods, and articles described herein are not limited to these.

The process 3000 may include a single process of uniformly or substantially uniformly coating the back surface 166 with a binder. In one example, the binder may be injected into the rear surface 166 and injected into the rear surface 166 by converting it into fine particles or droplets (i.e., atomized). Accordingly, the rear surface 166 can be uniformly or substantially uniformly coated with the binder in one process. The process of substantially uniformly coating the backside surface 166 with the bonding agent can be defined as a coating process with some non-uniformity due to the implantation process or fabrication process. However, this slight non-uniformity will not affect the process of bonding the filler material to the back surface 166 as the binder, as described herein. For example, spraying the binder onto the back surface 166 may result in overlapped injected areas where the binder has a slightly thicker coating thickness than other areas sprayed onto the back surface 166. [ The fabrication apparatus, methods, and articles described herein are not limited to these.

The second set of weight portions 3330 (e.g., weight portions 3331, 3332, 3333, 3334, and 3335) aligns the center of gravity of the golf club head 3300 in the optimal position and adjusts the weight of the golf club head 3300 And may be configured to optimize the moment of inertia of the golf club head about a vertical axis extending through the center. 34, all or a substantial portion of the second weight portion 3330 may be located close to the bottom portion 3390. [ For example, a second set of weight portions 3330 (e.g., weight portions 3331, 3332, 3333, 3334, and 3335) may extend between the toe portion 3340 and the heel portion 3350 to the bottom portion 3390 Extends or extends near the bottom portion 3390 to lower the center of gravity of the golf club head 3300. [ The weight portions 3334 and 3335 may be positioned closer to the toe portion 3340 than the heel portion 3350 and / or may be located in the transition region 3347 between the toe portion 3340 and the bottom portion 3390, 3347 to increase the moment of inertia of the golf club head 3300 about a vertical axis extending through the center of gravity. Some weight portions of the second set of weight portions 3330 may be located in the toe portion. All or a portion of the second set of weight portions 3330 may be positioned closer to the bottom portion 3390 than the horizontal center plane 4120 to lower the center of gravity of the golf club head 3300.

The fabrication apparatus, methods, and articles described herein are not limited to these.

37, for example, the first and second sets of weight portions 3320 and 3330 may be positioned away from the rear surface 3366 of the face portion 3362, respectively (e.g., Not directly bonded). This means that each of the first and second sets of weight portions 3320 and 3330 and the rear surface 3366 can be located at least partly by the inner cavity 3800 of the body portion 3300, . For example, each of the external weight ports of the first and second sets of external weight ports 3320 and 3330 may have an opening (e.g., generally designated 3820 and 3830) and a port wall (e.g., , Denoted by reference numerals 3825 and 3835). The port walls 3825 and 3835 may be an integral portion of the rear wall portion 3510 (e.g., a section of the rear wall portion 3510). Each of the openings 3820 and 3830 may be configured to receive a weight portion, e.g., a respective weight portion 3321 and 3335. [ The opening 3820 may be located at one end of the weight port 3521 and the port wall 3825 may be located at the opposite end of the weight port 3521 or close to the opposite end. Similarly, the aperture 3830 can be located at one end of the weight port 3535 and the port wall 3835 can be located at the opposite end of the weight port 3535 or close to the opposite end . Port walls 3825 and 3835 can be positioned away from face portion 3362 (e.g., can be located apart by inner cavity 3800). Each port wall of the first set of weight ports 3520 may have a distance 3826 from the rear surface 3366 of the face portion 3362, . Each port wall of the second set of weight ports 3530 may have a distance 3836 from the rear surface 3366 of the face portion 3362, The distances 3826 and 3836 can be adjusted such that the first and second sets of weight ports 3520 and 3530 are positioned at the center of gravity of the golf club head 3300 when receiving a weight portion as described herein, . &Lt; / RTI &gt; According to one example, distance 3836 is greater than distance 3826 such that the center of gravity of the golf club head 3300 may be moved toward and / or lower toward the rear portion 3370 towards the bottom portion 3390. According to one example, distance 3836 may be about 1.5 times to about 4 times greater than distance 3826. In other words, distance 3836 may be about 1.5 times to about 4 times distance 3826. As a result, the width 3840 (shown in FIG. 38) of a portion of the inner cavity 3800 below the horizontal center plane 4120 is greater than the width 3842 of the inner cavity 3800 over the horizontal center plane 4120. [ Lt; / RTI &gt; The fabrication apparatus, methods, and articles described herein are not limited to these.

As discussed herein, the center of gravity CG of the golf club head 3300 may be relatively far from the face portion 3362 and may be spaced apart from the ground (e.g., indicated at 4110 in FIG. 34) Relative to a golf club without a width 3840 of a portion of the inner cavity 3800 that is greater than the width 3842 of the inner cavity 3800 as described herein, The entire or substantial portion of the two sets of weight portions 3330 is positioned closer to the bottom portion 3390 than the horizontal centerplane 4120 and the first and second sets of weight portions 3320 and 3330 are positioned, The second set of weight portions 3330 are located farther away from the rear surface 3366 than when they are joined directly to the rear surface 3366.

Although the figures depict a weight port having a particular cross-sectional shape, the fabrication apparatus, methods, and articles described herein may include a weight port having other suitable cross-sectional shapes. The weight ports of the first and / or second set of weight ports 3520 and 3530 may have a cross-sectional shape similar to that of any of the weight ports described herein. Accordingly, a detailed description of the cross-sectional shapes of the weight ports 3520 and 3530 is not described in detail. The fabrication apparatus, methods, and articles described herein are not limited to these.

The weight portions 3320 and 3330 of the first and second sets may each be similar in mass (e.g., the weights of all weight portions 3320 and 3330 in the first and second sets are approximately the same). Alternatively, the weight portions 3320 and 3330 of the first and second sets may each be different in mass, individually or as a whole. In particular, each of the weight portions 3320 (e.g., shown at 3321 and 3322) of the first set may include a second set of optional weight portions 3330 (e.g., 3331, 3332, 3333 , 3334, and 3335). &Lt; / RTI &gt; For example, the second set of weight portions 3330 may be greater than 50% of the total mass from the outer weight portion of the golf club head 3300. As a result, the golf club head 3300 may be configured to have at least 50% of the total mass from the outer weight portion arranged below the horizontal center plane 4120. In one example, the total mass from the outer weight portion under the horizontal center plane 4120 may be greater than the total mass from the outer weight portion above the horizontal center plane 4120. The fabrication apparatus, methods, and articles described herein are not limited to these.

In one example, the golf club head 3300 may have a mass ranging from about 220 grams to about 330 grams, depending on the type of golf club (e.g., a four-iron stand, lobe wedge). The body portion 3310 may have a mass ranging from about 200 grams to about 310 grams and the first and second set of weight portions 3320 and 3330 may each have a mass of about 20 grams Total mass from the portions). Each weight portion 3320 of the first set may have a mass of about one gram (1.0 g) and each weight portion 3330 of the second set may have a mass of about 2.4 grams. The sum of the masses of the first set of weight portions 3320 can be about 3 grams and the sum of the masses of the second set of weight portions 3330 can be about 16.8 grams. The total mass of the second set of weight portions 3330 may be greater than five times the total mass of the first set of weight portions 3320 (e.g., about 16.8 grams of the second set of weight portions 3330) The total mass of the first set of weight portions 3320 to the total mass of about 3 grams). The golf club head 3300 has a total mass of 19.8 grams (e.g., 3 grams from the first set of weight portions 3320 and a second set of weights 3320 and 3330, respectively) from the first and second set of weight portions 3320 and 3330, The sum of 16.8 grams from portion 3330). Accordingly, the first set of weight portions 3320 can have about 15% of the total mass from the outer weight portion of the golf club head 3300, and the second set of weight portions 3330 can have a weight of the golf club head 3300 3300 &lt; / RTI &gt; of the total weight from the outer weight portion. The fabrication apparatus, methods, and articles described herein are not limited to these.

The first and second sets of weight portions 3320 and 3330 can be coupled to the body portion 3310, respectively (e.g., by coupling the first and second sets of weight portions 3320 and 3330 to the rear portion 3370) The position of the center of gravity CG and the moment of inertia MOI of the golf club head 3300 can be optimized. In particular, the first and second sets of weight portions 3320 and 3330 can each cause the position of the center of gravity CG to descend towards the bottom portion 3390 and further away from the face portion 3362 You may. In addition, the moment of inertia (MOI) may be as large as measured about a vertical axis extending through the center of gravity CG (e.g., perpendicular to the paper 4110). In addition, the moment of inertia (MOI) may be measured as a measure of the moment of inertia (e.g., as measured about a horizontal axis) extending through the center of gravity CG (e.g., extending toward the toe portion of the golf club head 3300 and toward the heel portions 3350 and 3360) . As a result, the club head 3300 may provide a relatively larger firing angle and relatively smaller rotational speed than the golf club head without the first and second sets of weight portions 3320 and 3330. The fabrication apparatus, methods, and articles described herein are not limited to these.

Alternatively, two or more weight portions of the same set may be different in mass. In one example, the weight portion 3321 of the first set 3320 may have a relatively smaller mass than the weight portion 3322 of the first set 3320. In yet another example, the weight portion 3331 of the second set 3330 may have a relatively smaller mass than the weight portion 3335 of the second set 3330. The larger weight is distributed away from the center of gravity CG of the golf club head 3300 so that the center of gravity CG can be shifted away from the center of gravity CG of the golf club head 3300 because a relatively large mass is provided in the upper- The moment of inertia (MOI) around the passing vertical axis is increased.

In the figures, the weight portions 3320 and 3330 of each set of first and second sets may each be an integral part of the weight portion, although the weight portion is located apart and shown as discrete portions. In one example, all weight portions 3320 of the first set (denoted, for example, by reference numerals 3321 and 3322) may be combined into an integral portion of the weight portion (e.g., the first weight portion). Similarly, all of the weight portions 3330 of the second set (denoted by reference numerals 3331, 3332, 3333, 3334, and 3335) may have an integral portion of the weight portion similar to the example of Figure 32 Portion). Although a certain number of weight portions are shown in the figures, the fabrication apparatus, methods, and articles described herein may include more or fewer weight portions.

The body portion 3310 may be a hollow body including an inner cavity 3800 extending between the forward portion 3360 and the rear portion 3370. In addition, the inner cavity 3800 may extend between the upper portion 3380 and the lower portion 3390. Inner cavity 3800 may be associated with cavity height 3850 (H _C ) and body portion 3310 may be associated with body height 3950 (H _B ). The cavity height 3850 and the body height 3950 may vary between the toe portion and the heel portion 3340 and 3350 and between the upper and lower portions 3370 and 3390, May be at least 50% of the height 3950 (H _C > 0.5 * H _B ). For example, the cavity height 3850 may vary between 70-85% of the body height 3950. When the golf club head 3300 hits the golf ball by the face portion 3362, if the joint height 3850 of the inner cavity 3800 is greater than 50% of the body height 3950, The golf club head 3300 may produce a relatively more consistent tactile, sound, and / or result, as compared to the case where the golf club head 3300 is at a cavity height less than 50% of the height.

Internal cavity 3800 may be associated with cavity width 3840 (W _c ) and body portion 3310 may be related to body width 3990 (W _B ). Cavity width 3840 and body width 3990 may be varied between upper portion 3380 and lower portion 3390 and between toe portion 3340 and heel portion 3350. Cavity width 3840 includes body width 3990 in certain areas on body portion 3310 between upper and lower portions 3370 and 3390 and between the upper and heel portions 3340 and 3350. [ (W _c > 0.5 * W _B ). According to yet another example, cavity width 3840 may vary between about 40% and 60% of body width 3990 in certain regions between the upper and lower portions 3380 and 3390. [ According to yet another example, cavity width 3840 may vary between about 30% and 70% of body width 3990 in certain regions between the top and bottom portions 3380 and 3390. [ According to yet another example, cavity width 3840 may vary between about 20% and 80% of body width 3990 in certain areas between the upper and lower portions 3380 and 3390. [ For example, cavity width 3840 may vary between about 20% and 80% of body width 3990 at horizontal center plane 4120 or below horizontal center plane 4120. The cavity width 3890 of the inner cavity 3800 is varied between about 20% or more and about 80% or less of the body width 3990 in the horizontal center plane 4120 or below the horizontal center plane 4120 If practicable, a substantial portion of the mass of the golf club head 3300 can be moved down and moved back relative to the golf club head having a cavity width less than about 20% of the body width. In addition, when the golf club head 3300 hits the golf ball with the face portion 3362, the golf club head 3300 has a smaller width than the golf club head 3300 having a cavity width less than about 20% Sound, and / or results that are relatively constant. The fabrication apparatus, methods, and articles described herein are not limited to these.

In order to provide an inner cavity 3800 with a cavity width 3840 that can vary between about 20-80% of the body width 3990 in a horizontal center plane 4120 or under a horizontal center plane 4120, In order to lower the center of gravity CG of the club head 3300 and / or to move the center of gravity CG of the golf club head 3300 further back to the face portion 3360, the rear portion 3370 35, 36, and 39), which may be positioned as long as it is in the upper portion 3380 or as close to the upper portion 338 and the horizontal center plane &lt; RTI ID = 0.0 &gt;Lt; RTI ID = 0.0 &gt; 4120. &lt; / RTI &gt; The recessed portion 3410 may be formed by the recessed portion 3414 and the upper wall 3412 of the rear portion 3370. The top wall 3412 of the rear portion 3370 is positioned as far as it is in the horizontal center plane 4120 or in a position in the upper portion 3380 or near the upper portion 3380, Position. The ledge portion 3414 may extend from the top wall 3412 of the rear portion 3370 to the bottom wall 3416 of the rear portion 3370. The bottom wall 3416 of the rear portion 3370 is positioned as far as it is in the bottom portion 3380 or near the bottom portion 3380 in the horizontal center plane 4120 or as long as it is close to the horizontal center plane 4120 Position. The ledge portion 3414 may extend from the top wall 3412 in a direction away from the face portion 3360. Thus, the recessed portion 3414 facilitates the transition from the top wall 3412 to the bottom wall 3416 so that the width of the body portion 3310 is greater than the width of the body portion 3310 In the horizontal center plane 4120 or near the horizontal center plane 4120. [ The ledge portion 3414 may have a larger ledge width 3418 (shown in Figure 39) that is larger than the upper body width 3420 of the body portion 3310. [ In one example, the recessed portion width 3418 is between the plane 3413 forming the top wall 3412 of the rear portion 3370 and the plane 3417 forming the bottom wall 3416 of the rear portion 3370 May be formed with a width of one surface on the extending rear portion 3370. The upper body width 3420 can be formed in the horizontal center plane 4120 or on the horizontal center plane 4120 with the width of the body portion 3310. According to one example, the ridge portion width 3418 may be about 0.5 to about 1.0 times wider than the upper body width 3420. According to another example, the ridge portion width 3418 may be about 1.5 times wider than the upper body width 3420. According to another example, the leg portion width 3418 may be about 3.0 times wider than the upper body width 3420. Accordingly, a golf club according to the examples described herein has a limb portion width 3418 that is greater than about 0.5 times, or about 0.5 times, about 3.0 times, or about 3.0 times greater than the upper body width 3420 . Accordingly, in the horizontal center plane 4120, near the horizontal center plane 4120, or below the horizontal center plane 4120, the body width 3990 may be substantially larger than the upper body width 3420, It is possible to provide a cavity width 3840 that can be about 20% to 80% of the body width 3990, in the horizontal center plane 4120, near the horizontal center plane 4120, or below the horizontal center plane 4120 have. In addition, the recessed portion 3410 allows the golf club head 3300 to have a greater mass below the horizontal midplane 4120 than over the horizontal midplane 4120. In other words, the mass removed from the golf club head 3300 to form the recessed portion 3410 is directed toward the rear or rear of the body portion 3310, which is arranged below the horizontal center plane 4120 and around the horizontal center plane 4120 . &Lt; / RTI &gt;

The cavity width 3840 is greater than the horizontal center plane 4120 or near the upper portion 3380 to maintain the cavity width 3840, which can generally be about 20% -80% of the body width 3990. [ May be larger underneath the plane 4120 or near the bottom portion 3390. According to one example, the cavity width 3840 is greater than the body width 3340 in certain areas of the body portion 3310 between the heel portion 3350 and the toe portion 3340 and between the bottom portion 3390 and the upper portion 3380 3990). &Lt; / RTI &gt; 40, the cavity width 3840 generally corresponds to the body width 3990 in certain areas of the body portion 3310 between the bottom portion 3390 and the upper portion 3380. For example, can be changed. The fabrication apparatus, methods, and articles described herein are not limited to these.

In one example, the inner cavity 3800 may not be filled (i.e. it may be hollow). The body portion 3300 with the inner cavity 3800 may have a weight less than about 100 grams less than the body portion 3300 without the inner cavity 3800. [ In the alternative, the interior cavity (3800), at least partially, the elastic polymer or elastomer material (e.g., viscoelastic polyurethane polymer material, for example, the United States, OH, located in Kent City Sober X Saga produced Sober X ^® materials), thermoplastic (TPE), a thermoplastic polyurethane material (TPU), and / or any other suitable type of material to absorb shock, isolate vibration, and / or attenuate noise. For example, at least 50% of the internal cavity 3800 may be configured to absorb impact, separate vibration, and / or noise when the golf club head 3300 hits the golf ball with the face portion 3362 RTI ID = 0.0 &gt; TPE &lt; / RTI &gt;

In another example, the inner cavity 3800 may be configured to partially or wholly absorb the impact, disengage the vibrations, and / or reduce vibrations when the golf club head 3300 hits the golf ball with the face portion 3362. [ Or may be filled with a polymer material, such as an ethylene copolymer material, to attenuate noise. In particular, at least 50% of the inner cavity 3800 includes a high density ethylene copolymer ionomer, a fatty acid modified ethylene copolymer ionomer, a high amorphous ethylene copolymer ionomer, an ionomer of an ethylene acid acrylate terpolymer, an ethylene copolymer comprising a magnesium ionomer , Injection moldable ethylene copolymers that can be used in conventional injection molding apparatus to form various shapes, ethylene copolymers that can be used in conventional extrusion apparatus to form various shapes, and / or thermosetting polybutadiene rubbers Can be filled with an ethylene copolymer having high compressibility and low elasticity. For example, ethylene copolymers can be made from any of the ethylene copolymers associated with the DuPont ™ high-performance resin (HPF) material family (eg DuPont ™ HPF AD1172, DuPont ™ HPF AD1035, DuPont® HPF 1000 and DuPont ™ HPF 2000) Which is manufactured by DuPont in Wilmington, Delaware, USA. The DuPont (TM) HPF ethylene copolymer family can be injection molded and used with conventional injection molding apparatus and molds to provide low compressibility and high resilience. The fabrication apparatus, methods, and articles described herein are not limited to these.

The cavity width 3840 can be varied between about 20% and 80% of the body width 3990 in the horizontal center plane 4120 or below the horizontal center plane 4120, as described herein. According to one example, at least 50% of the elastic polymer or elastomeric material that partially or wholly fills the inner cavity 3800 may be positioned below the horizontal center plane 4120 of the golf club head 3300. Accordingly, the center of gravity of the golf club head 3300 has a cavity width that is less than about 20% of the body width, that is, moves further downward relative to a golf club head that is partially or fully filled with an elastomeric or elastomeric material, Can be moved. In addition, when the golf club head 3300 hits the golf ball by the face portion 3362, the golf club head has a cavity width less than about 20% of the body width, that is, partially or entirely filled with an elastomeric polymer material The golf club head 3300 may produce a relatively more consistent tactile, sound, and / or result.

The thickness of the face portion 3362 may vary between the heel portion and the toe portion 3340 and between the bottom portion and the upper portion 3380 as illustrated in the examples of Figs. 15 and 16 and discussed in detail herein . Therefore, the change in the thickness of the face portion 3362 is not described in detail. The fabrication apparatus, methods, and articles described herein are not limited to these.

Due to the position of the inner cavity 3800 of the body portion 3310 and the first and second set of weight portions 3320 and 3330, unlike other golf club head designs, the periphery of the golf club head 3300 The golf ball will move away from the face portion 3362 at a relatively higher ball throw angle and at a relatively low rotational speed. As a result, the golf ball can move farther (i.e., the total distance including the carry distance and the roll distance can be larger).

The golf club head 3300 is illustrated in FIG. 17 and may be manufactured by any of the methods described herein. Accordingly, the method of making the golf club head 3300 is not described in detail.

As illustrated in Figures 37 and 41, for example, the golf club head 3300 is shown as one or more weight ports (e. G., Weight ports 3521 and 3531, which may be open to the inner cavity 3800) Weight port). The weight port 3531 may include a first opening 3930 and a second opening 3935. The second opening 3935 can be used to access the inner cavity 3800. In one example, the process 1700 (FIG. 17) includes injecting elastic polymer material from the first opening 3930 into the inner cavity 3800 through the second opening 3935 to form an inner cavity 3800 ). Each of the first and second openings 3930 and 3935 may be the same or different in size and / or shape. The weight port 3521 may include a first opening 4030 and a second opening 4035. The second opening 4035 can be used to access the inner cavity 3800. In one example, the process 1700 (FIG. 17) can fill the inner cavity 3800 with an elastomeric polymer material by injecting elastic polymer material from the weight port 3531 into the inner cavity 3800. As the resilient polymer material fills the inner cavity 3800, air in the inner cavity 3800 that is moved by the elastic polymer material flows from the weight port 3521 through the second opening 4035 to the first opening 4030 &Lt; / RTI &gt; After the inner cavity is partially or fully filled with the elastomeric polymer material, the weight ports 3531 and 3521 can be sealed by inserting and securing the weight portion therein, as described in detail herein. Alternatively, the elastomeric polymer material may be injected from the weight port 3521 into the inner cavity 3800. Accordingly, the weight port 3531 can function as an exit port for the air that has been moved within the inner cavity 3800. Any other weight port (e.g., weight port 3532) of the golf club head 4200 may include a second aperture, although the example describes and illustrates a particular weight port with a second aperture.
