Description of the Invention () The present invention relates to golf balls, and particularly relates to a method for manufacturing a golf club head. Most conventional golf heads are first manufactured with a ball head housing and a hitting panel. The ball head housing can be a two-piece type, a three-piece combination, or an integrated five-shaped body. Soft materials, such as s25 (: made of broken steel, iron, or aluminum alloy, make the ball head have better vibration damping effect. The hitting panel is the part intended to contact the ball, so it is mostly with high hardness Made of materials, most of the current high-end clubs are made of titanium alloy as the material of the hitting panel. One aspect of the research made by the ball head manufacturer is how to fix the 10 hitting panel to the head shell. Physically, the batting panel will not fall off even after a long swing.

Please refer to the first and fifth figures. The method for manufacturing a golf club head according to a preferred embodiment of the present invention includes the following steps: 1. Take a pre-made golf club head (10), It is made of low carbon steel, such as S25C, which makes the head (10) more vibrating than the south. An impervious layer (20) is provided on the surface of the 15 head (10) by coating. Please refer to the third figure. The impervious agent used in the impervious layer (20) can break the glass with water. To do this, make the head (10) have a specific area without the impervious layer (20), and the specific area is the predetermined position of the hitting face (11) of the head (10). A plurality of line grooves (12) are provided. 20 There are two ways to make the surface of the striking face (11) without the impervious layer (20). One is to set the surface of the striking face (11) before applying the impervious layer (20). A cover (not shown in the figure), after the coating is completed, the reading cover is removed. Second, after the impervious layer (20) is coated on the head (10), the batting face (11) is partially subjected to grinding, sand blasting and other steps to remove the batting face (U) surface-4 prayer This paper size applies to China National Standard (CNS) A4 specification (210X297 mm) " · ~~-(Please read the precautions on the back before filling this page] Order 509585 A7 B7 V. The description of the invention () Carburizing layer 2. Please refer to the fourth figure to harden the ball striking surface (11) of the head (10). The conventional hardening method includes at least two methods, such as carburizing and nitriding. The carburizing method includes: gas carburizing method, salt bath carburizing method and vacuum carburizing method (the same as the nitriding method), which should all belong to the scope of the present invention. When the surface hardening treatment step is completed Then, the material of the striking face (11) of the head (10) near the surface will form a hardened layer (30). That is, the hardened layer (30) is a part of the material of the head (10) Even after the club head (10) is subjected to multiple 10 swings, the hardened layer (30) will not be detached as in the conventional hitting panel. Yes. 3. Remove the impervious layer (20) formed by water glass. 4. Heat treat the head (10), including steps such as quenching and tempering, to make the head (10) The mechanical properties are further enhanced. The control of the heat treatment temperature and 15 time is a conventional technique, which will not be described in detail here. 5. Please refer to the third figure, and plate the surface of the head (10) to make the rod. The surface of the head (10) is covered with a covering layer (40). Most of the manufacturing processes of golf club heads include processes such as plating and heat treatment, so in practice, the golf club head provided by the present invention is not 20 There will be situations where the manufacturing process is complicated or the manufacturing cost is greatly increased. The hardened layer (30) formed by the surface hardening treatment method provided by the present invention has an effective depth of about 0.05 to 0.8 legs and a hardness higher than HRC Above 60, and the hardened layer (30) is a part of the material of the head (10), even after the head (10) is swung for many times, the hardened layer (30) will not be as known Batting panel-5- This paper size applies to China National Standard (CNS) A4 specification (210X297 PCT) (Please read the notes and then fill in the back of this page)
