Abstract:
1. A method of joining wax patterns for fabricating a golf club head, comprising the steps of: providing a prefabricated first wax pattern and a prefabricated second wax pattern, wherein the first wax pattern has a recess portion adapted for the second wax pattern to be embedded therein, a flange is formed on at least an edge of the recess portion, and the second wax pattern has a joining portion with a shape corresponding to that of the recess portion and a chambered receiving portion with a shape corresponding to that of the flange; embedding the joining portion into the recess portion; heating the flange to make the flange soften; and using a flattening tool to fold the flange over and into the chambered receiving portion such that the flange and receiving portion are melted into a whole, the joint surfaces of the first wax pattern and the second wax pattern are joined tightly with no gaps, and a single wax pattern is formed.
