Method for combining wax patterns for making a golf club head and combined wax pattern thereof

Abstract

A method for combining wax patterns for making a golf club head includes the steps of: prefabricating a first wax pattern and a second wax pattern to constitute a combined wax pattern, and at least one of connection surfaces of the first and second wax patterns providing a cutout portion to form an injection notch on a boundary line of the combined wax pattern; and inserting the first wax pattern and the second wax pattern into a mold assembly, and injecting liquid wax into the injection notch to form a wax-connection portion between the first wax pattern and the second wax pattern. Accordingly, the wax-connection portion is integrally connected between the first wax pattern and the second wax pattern to constitute the combined wax pattern.
