Abstract
A method for manufacturing a golf club head with a disparate metallic material provided on a hosel side of the head, which can improve degree of freedom in the design of a head. A head body is made up of a columnar material body 13 made from a forgeable metallic material such as copper and a disparate metallic member 12 as an axial member. The disparate metallic member 12 has its proximal end 12A inserted into a bore 14 formed along a center of axis of the material body 13, while its distal end 12B protruded in the axial direction X. The material body 13 is placed on a lower die 22 which is formed with a mold 21 defining a contour of the head body 11, and then an upper die is pressed thereto. Thus, hot forging process is carried out to form a golf club head.
Claims6
A method for manufacturing a golf club head, comprising the steps of:
- subjecting a metallic material to a hot forging, using a die so as to form a golf club head prototype having a hosel on one side of a face;
- and then
- subjecting a thus formed prototype to a finishing process,
- wherein said metallic material is composed of:
- a material body made from a forgeable material;
- and a disparate metal material provided integrally with said material body so as to protrude therefrom, said disparate metallic member having smaller specific gravity and different composition than said material body, and
- wherein said metallic material is subjected to hot forging with said material body being disposed in a face corresponding portion in said die, and said disparate metallic member being disposed in a hosel corresponding portion in said die.

- and then
- subjecting a thus formed prototype to a finishing process,
- wherein said metallic material is composed of:
- a material body made from a forgeable material, said material body having a bore;
- and a disparate metallic member provided inside said bore, said disparate metallic member having smaller specific gravity and different composition than said material body, and
- wherein said metallic material is subjected to hot forging with said material body being disposed in a face corresponding portion and a hosel corresponding portion in said die, and said disparate material being disposed in a substantially intermediate portion between said face corresponding portion and said hosel corresponding portion.
