Method for making golf club head
First Claim
1. A method for making a golf club head, comprising steps for processing upper and lower shells of the golf club head, the steps including:
- a. providing a metal-based or non-metal-based composite material which has a necessary thickness and whose area and total width are large enough to make at least two unit shells in an alternate or non-alternate arrangement, as determined by widths and surface curvatures of the upper and lower shells of the golf club head to be pre-processed, in which a strip of excess material is reserved at a border between the two unit shells for constraining an extension force generated while the unit shells are formed;
.b. integrally forming the two alternately or non-alternately arranged unit shells through a forming process, wherein the extension force generated while the two unit shells are formed is constrained by the excess material at the border between the unit shells; and
c. cutting off the excess material from the two formed unit shells to produce the upper and lower shells of the golf club head, wherein the upper and lower shells have smooth ends of parts and close contact surfaces.

Abstract
A method for making a golf club head includes steps for processing upper and lower shells of the head. A metal- or non-metal-based composite material is provided which has a necessary thickness and whose area and total width are enough for making at least two unit shells, as determined by widths and surface curvatures of the upper and lower shells. A strip of excess material is reserved at a border between the unit shells. The two alternately or non-alternately arranged unit shells are integrally formed through a forming process, wherein an extension force generated while the unit shells are formed is constrained by the excess material to reduce deformation of the unit shells, so that the formed unit shells have flat cutting surfaces when the excess material is cut off, allowing the upper and lower shells thus made to have precise dimensions, improved ends of parts and close contact surfaces.
