Patent ID: 8214992

Claim:
A method for manufacturing a golf club head comprising: a step of preparing a non-flat metal face member which comprises a main portion forming at least a part of a club face for striking a ball and a turnback extending backward from at least a part of the peripheral edge of the club face; a step of preparing a metal head main body; and a step of welding the non-flat metal face member to the metal head main body, wherein the step of preparing said non-flat metal face member comprises: a process (a) in which a rolled metal plate having a constant thickness is prepared; a process (b) in which an in-process face material is cut out from the rolled metal plate after the process (a); a process (c) in which the face member is prepared by forming the turnback by subjecting the in-process face material to a press working after the process (b); a process (d) in which, in the outer surface of a corresponding-to-turnback region corresponding to the turnback, an inclined surface inclined to the inner surface of corresponding-to-turnback region towards the peripheral edge of corresponding-to-turnback region is formed by a cutting work carried out before the process (c) in a state of the in-process face material or in a state of the rolled metal plate so that the thickness of the corresponding-to-turnback region is continuously decreased towards the peripheral edge of the corresponding-to-turnback region.
