Abstract:
1. A manufacturing method for a golf club head, comprising the steps of: prefabricating a first wax pattern in a first molding assembly, the first wax pattern having a connecting portion; inserting the first wax pattern into a first mold cavity of a second molding assembly which has a configuration substantially corresponding to that of a first component of the golf club head; filling liquid wax into a second mold cavity of the second molding assembly which has a configuration substantially corresponding to that of a second component of the golf club head; cooling the liquid wax in the second mold cavity to form a second wax pattern joined to the connecting portion of the first wax pattern such that the first wax pattern and the second wax pattern are joint to constitute a hybrid one-piece design of the wax pattern of the golf club head; dipping the wax pattern of the golf club head in slurry to form a ceramic shell, and melting the wax pattern in the ceramic shell in dewaxing; and forming a casting in the ceramic shell in casting.
