Finally, the head primordial 70d is subjected to several surface processing to obtain a finished head with a predetermined specification [not shown]. Although, the forging is shaped The finished product of the club head has the advantages of steel and strong, etc., but because the forging process uses too many forging dies / 丨 to Ud number; E, it easily leads to high mold opening and manufacturing costs, which is not suitable for mass production. Deformation must be changed frequently due to pressure. At the same time, the forging process also hangs because the process of the δ metal block to the head embryo has a large amount of Mai Kai V ', which caused the cavity 7 2 a to 7 2 d. Pressure deformation, so that the finished filial piezo head can not maintain the standard size specifications.

C: M〇e〇-5SFivc Co „llncnisNPKyi7Ra. Page 6 Another conventional method for manufacturing Nanlf club heads, as shown in Figure 8, is to make a club head product by butterfly casting, and its manufacturing process First, a mold 81 is prepared, which is provided with a mold cavity 811, which has the specifications of a predetermined club head finished product; then, a wax is injected into the mold cavity 8 11 of the mold 81 to form a mold 80; since Take out the wax pattern 80 from the mold cavity 811, and dip the wax pattern 80 into 586950.

The cast into a dry head. 0 has the advantages of reducing manufacturing costs and being suitable for mass production, and the performance of its finished head in mechanical properties such as tensile strength, abrasion and metal fatigue is almost equivalent to that of a forged finished head. However, as shown in Fig. 9, because the casting process is often accompanied by the formation of bad slag holes 84 (or sand holes, air holes) on the surface of the head primary embryo 83, when the surface of the head primary embryo 83 is insufficiently polished or When the polishing is excessive, the finished product of the head will cause problems such as residual slag holes 84 or distortion of the ruler, or poor fluidity of the molten metal. Γ cannot be filled in the ceramic shell outer mold 82 during casting. Poor formability after casting. In particular, for manganese and aluminum with poor casting properties σ to s [its viscosity is too high], the problem of the slag hole ^ is very heavy, and it may even affect the yield of the finished club head shaped by the material scale. . Furthermore, for example, gold such as 862 0 and 4 130, the flow f of the molten metal of the alloy material is not good, and the molten metal using the wax mold casting method described above cannot be filled in the ceramic shell outer mold 82. Therefore, a good initial embryo shape cannot be obtained. However, the metal materials described above have the property of low hardness. It is about 1 right to make it into a golf club head system. It has the characteristics of extravagant and extravagant. Its ductility is high, and it has several advantages that can be adjusted freely to the required angle according to the needs of the user.
