Golf club
First Claim
1. A golf club head comprising:
- a main body having a hosel, a crown opening, a first sole opening, a second sole opening, and a face opening, the main body including a first thermoplastic material suitable for injection molding;
a composite crown insert joined to the main body and overlying the crown opening;
a composite sole insert joined to the main body and overlying the first sole opening and the second sole opening, the crown and sole inserts each including a polymeric material; and
a metal face plate frame joined to the main body and including a peripheral edge, the metal face plate frame being distinct from the main body and configured to receive a face plate;
wherein the main body comprises a first weight port located between the first sole opening and the second sole opening in an aft portion of the main body, and a second weight port located in a forward portion of the main body adjacent the face opening; and
wherein the main body is injection molded around the metal face plate frame and mechanically captures the peripheral edge of the metal face plate frame.

Abstract
In one embodiment the golf club head includes three main components, a frame component, a rear cap component, and a striking plate.
In another embodiment the club head may also comprise a front component, which is manufactured as a single unitary piece, and a rear cap component. The front component may also be overmolded by a thermoplastic polymeric outer portion which may or may not cover the striking face and which provides additional reinforcement at the load bearing sections of the club head and allows a more facile connection to the rear cap component.
In another embodiment, a club head having a main body, crown insert, sole insert and metal face plate frame is formed by forming the sole insert and crown insert from a polymeric material using a thermoforming or thermosetting process and then injection molding the main body over the sole insert, crown insert and metal face plate frame.
