Abstract

A method for forming a fairway-type golf club head having a composite crown is disclosed herein. The method includes casting a subassembly, compression molding a crown component, and bonding the crown component to the subassembly.

Claims

1. A method for forming a fairway type golf club head, the method comprising:

casting a golf club head subassembly from a titanium alloy material, the subassembly comprising a face component and a sole component, the face component comprising a striking plate section and a return section, the return section having a bonding flange of approximately 0.200 inch extending rearward;

compression molding a crown component from a graphite compound, the crown component having a bonding flange;

bonding the crown component to the golf club head subassembly using an adhesive to create an unfinished golf club head; and

finishing the unfinished golf club head to create a fairway-type golf club head.

2. The method according to claim 1 wherein the bonding flange of the crown component does not overlap the bonding flange of the face component.

3. The method according to claim 1 wherein the face component further comprises a hosel.

4. The method according to claim 3 wherein the hosel is an interior hosel.

5. The method according to claim 3 wherein the hosel is an exterior hosel.

6. The method according to claim 1 wherein the fairway-type golf club head has seven grams of additional discretionary mass as compared to high performance golf club head construction.

7. The method according to claim 1 wherein the face component has a milled variable face thickness pattern.
