Description

ABSTRACT:
A golf club head having a front surface with a substantially planar face, a lower edge and a ball impact area, is constructed with a composite core of metal and plastic, with the core being enclosed in an injection molded plastic sheath. The core may be formed of layers of metal and plastic, or an injection molded plastic having metal particles dispersed therein. The metal to plastic weight ratio is preferably from about 90:10 to about 10:90. For putter heads, the head also includes a resilient section in the front surface having a face flush with the front surface, a lower edge aligned with the front surface lower edge, and an upper edge below the ball initial impact area. An exposed section of the non-resilient core may serve as the initial striking surface, while a front section of the resilient sheath may serve as the second ball striking surface.
