Benefits of technology

"The present invention is about a golf club head with a striking plate that has a larger region with a high COR (crystalline orientation region) for better performance. The striking plate has a first crystallization phase region with a larger elastic modulus than the second crystallization phase region, which is located inside the first region and extends from the striking surface to the interior of the striking plate. The second crystallization phase region has a lower elastic modulus, which makes the region with a high COR larger. The method of fabricating the striking plate involves heating and quenching the plate body to create the second crystallization phase region with a lower elastic modulus. The method is simple and cost-effective."

Problems solved by technology

Therefore, in the conventional design of striking plate of the golf club head, the thickness of the plate is reduced to increase the striking restitution capability, but meanwhile the durability of the striking plate is degraded.
The striking plate may be easily damaged after a long time of striking as the thickness is reduced.
How to simply and effectively increase the striking restitution capability of the striking plate without degrading the durability has become an urgent problem to be solved in the design of the golf club head.

Embodiment Construction

[0029]Referring to FIGS. 1 and 2, FIG. 1 is a schematic exploded view of a golf club head according to an embodiment of the present invention, and FIG. 2 is a schematic side view of the striking plate of FIG. 1. The golf club head 200 of this embodiment includes a head body 210 and a striking plate 220. The head body 210 has an opening 212. In this embodiment, the head body 210 may be a shell, and integrally formed by a common metal material (e.g., stainless steel) by way of lost-wax casing.

[0030]Alternatively, in other embodiments of the present invention, the head body 210 may be made of composite material of metal and high molecular plasticizing material or high strength fiber material (e.g., carbon fiber), and it is fabricated by the following steps. A crown (not shown) is separately prefabricated by injection molding or thermal compression molding, and then, the crown is embedded into another part of the metal shell. Alternatively, a carbon fiber pre-preg may be directly adhere...

Abstract

A golf club head including a head body and a striking plate is provided. The head body has an opening. The striking plate is disposed at the opening and has a striking surface. The striking plate includes a first crystallization phase region and at least a second crystallization phase region. The second crystallization phase region is located in the first crystallization phase region. The second crystallization phase region extends from the striking surface to an interior of the striking plate. The elastic modulus of the second crystallization phase region is smaller than that of the first crystallization phase region.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims the priority benefit of Taiwan application serial no. 95139354, filed Oct. 25, 2006. All disclosure of the Taiwan application is incorporated herein by reference.BACKGROUND OF THE INVENTION[0002]1. Field of Invention[0003]The present invention relates to a golf club head and a method of fabricating a striking plate, and more particularly to a golf club head with a striking plate having a crystallization phase region with a low elastic modulus and a method of fabricating the striking plate.[0004]2. Description of Related Art[0005]With the prevailing of sports in today's society, golf has become one of the favorite sports widely accepted by the mass, and more and more people are participating in the golf sports. Golf clubs can be classified into wooden clubs, iron clubs, putters, and so on according to various fields and usage.[0006]As for the wooden club, the golf club head is usually fabricated by first forming a he...
