Abstract
A method of assembly of construction and assembly of golf club head parts used to manufacture golf club heads primarily composed of strong plastic materials that can be formed by injection plastic molding processes in a minimum of two parts. Draft is practical for both molded parts to simplify mold making. A preferred plastic is polycarbonate. Internal reinforcement elements are designed and arranged to provide structural features to facilitate assembly and improve strength of bonds. Internal reinforcement elements may be molded as separate parts to join with the face and shell structure. A hosel, which is not considered part of the shell and which may be made of plastic or metal, is bonded into the golf club head parts described.
