Term " is formed with defective " or " it is defective to be shaped " is meant that the defective (hole) in the underproof capsule spare 32 of shaping does not engage by bonding bar crown parts fully under predetermined internal pressure because of shown in Figure 4 causing.Produce bubble by the golf driver head of manufacturing being immersed in the water, can find that this shaping is defective whether to check from the composition surface of bar crown parts.
As seen, compare with the shaping disqualification rate in the comparative examples 1 and 2 from table 1 and 2, the shaping disqualification rate in the example 1,2 and 3 is very low, and this manufacturing that shows described three examples is very effective.And, similar to conventional golf driver head, the metal derby that is used to regulate center of gravity can be arranged in the hollow bulb, thereby not change the characteristic of golf driver head.
Described the manufacture method of golf driver head of the present invention above in detail.Yet the present invention is not limited to above-mentioned example.Certainly also can under the condition that does not depart from thought of the present invention, carry out various types of improvement and change.
Industrial applicibility
As mentioned above, according to the present invention, the hollow bulb surface of golf driver head comprises one of concave curved surface and plane or whole. On the other hand, being arranged on the protuberance on hollow bulb surface-if any-form has radius of curvature and is equal to or greater than the convex surface of 3mm or carries out chamfering with C3 or higher standard. Therefore, even use capsule spare to carry out interior pressing formation, also can make efficiently golf driver head, because the shaping disqualification rate when being shaped like this reduces the characteristic of having guaranteed again golf driver head simultaneously.
