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.

Claims

1. A golf club head having a face, sole, crown, heel and toe, the club head comprising:

a face component having surfaces defining the face, a sole return portion, a crown return portion, a toe return portion, and a heel return portion; and

a rear shell joined to the face component at the sole return portion, crown return portion, toe return portion and heel return portion, the rear shell comprising at least in part a polymeric material;

wherein the rear shell is joined to the face component by one or more of a crown insert, sole insert or skirt insert, the one or more inserts being overmolded by the rear shell and creating a discontinuity between the face component and rear shell to form a channel.

2. The club head of claim 1 wherein the face component is made of a metal or metal alloy.

3. The club head of claim 2 wherein the polymeric material is selected from the group of thermoset polyurethanes, thermoset polyureas, thermoplastic polyurethanes, thermoplastic polyureas, polyamides (PA), polyketones (PK), polyphenylene sulfides (PPS), polyphthalamides (PPA), thermoplastic urethane (TPU) and any combination thereof.

4. The club head of claim 1 wherein the rear shell is selected from the group of thermoset polymers and thermoplastic polymers.
