Abstract

A wood club head includes a hollow base, a top panel and a striking face. The base is integrally formed by casting and has a top opening and a front opening defined therein. A flange extends inwardly from a periphery defining the top opening. The top panel and the striking face are integrally formed together by forging. The top panel is welded onto the base and along an edge of the flange to cover the top opening. The striking face is welded onto the base to cover the front opening. Therefore, the present invention utilizes the advantages of casting and forging to create a high performance club head. Moreover, the welding between the top panel and the base is performed on the flange which extends substantially away from corner edges of the club head to prevent damaging of rigidity of the wood club head.

Claims

1. A wood club head comprising:

a hollow base integrally formed by casting, and having a top opening, a front opening defined to communicate with the top opening and a flange extending inwardly along a top periphery defining the top opening and an outer edge of the flange connects to an outer edge of the front opening so that the top opening and the front opening are in direct communication with one another;

a top panel and a striking face are integrally formed together, wherein the top panel is welded onto the hollow base along the outer edge of the flange to cover the top opening, and the striking face is welded onto the hollow base along the outer edge of the front opening to cover the front opening; and

wherein a thickness of the hollow base is not less than 1 mm, a thickness of the top panel is between 1 mm and 1.5 mm, and a thickness of the striking face is between 2.4 mm and 3 mm.

2. The wood club head as claimed in claim 1, wherein the top panel and the striking face are integrally formed together by forging a single metal piece.
