Abstract
A method of forming a golf club head that is capable improving on the inertia properties of a golf club head all while also improving the Center of Gravity (CG) location is disclosed herein. More specifically, the method forms a golf club head that achieves a relative low Moment of Inertia (MOI) about the Z-axis (MOI-Z) as well as a relatively low MOI about the Shaft-axis (MOI-SA).
Claims5
A method of forming a golf club comprising the steps of:
- forming a frontal portion comprised of a crown return, a sole return and a striking face, comprised of titanium;
- forming a rear portion and a plurality of support members therein by:
- forming a wax rear portion comprised of a wax crown at an upper portion and a wax sole on a bottom portion;
- forming a plurality of wax support members;
- coupling the wax support members to an inner surface of the wax rear portion such that the wax support members extend from the wax crown to the wax sole and from a back edge toward a front edge of the wax rear portion, wherein a first wax support member is coupled to the wax rear portion near a central portion of the wax rear portion in a heel-to-toe orientation, to form a final rear wax;
- and
- using the final rear wax to cast the rear portion and the plurality of support members from titanium;
- and
- welding the rear portion to the frontal portion.
