Abstract A plastic golf club head is formed in two major parts, a body member and a faceplate. Complementary dovetail members are provided on the body member and face plate so that the faceplate may be founded by sliding it onto the body member. To prevent movement therebetween when in position, an insert plug is inserted in channels provided in both the body member and faceplate in mutual registry. One or more plugs and complementary channels may be utilized. The plugs may be of any desired cross section. However, when only one plug is utilized, it should preferably have a noncircular cross section such as rectangular to prevent rotational movement of the faceplate. Where two or more plugs are utilized, they may be of any cross section. A screw is inserted either through the faceplate and engaged by a threaded insert in the body member, or alternatively inserted through the body member and engaged in a threaded means provided either in the insert plug or in the body member. The structure permits ready changing of the faceplate to provide the club head with various striking contours and angles. The insert plugs are preferably of the same cross section as the entry ducts of the mold used for molding of the plastic heads, so that the ''''trees'''' from molding of the heads may be used for insert plugs.
A method for the manufacture of a golf club head of the wood type having a body portion and a faceplate which comprises the steps of: providing a mold cavity contoured for molding the body portion, containing a core member therewithin adapted to provide a channel extending within the body portion, and having an entry duct with the inner peripheral contour thereof complementary to the outer peripheral contour of said core member; introducing a molding composition into said mold cavity and said entry duct so as to form said body portion and an elongated plug within said entry duct; severing said plug from said body portion and using at least a portion thereof as an insert within said channel; affixing a faceplate to said body portion; and engaging said plug insert with said faceplate.
