Benefits of technology

[0007]The primary objective of the present invention is to provide a golf club head and a method for making the golf club head, wherein all part or partial of the changeable zone of the hitting face has a hardness different from (greater or smaller than) that of the hitting face, so that when the changeable zone is harder than the hitting face, the golf club head provides a greater hitting force on the golf ball due to the greater hardness of the changeable zone to increase the travel distance of the golf ball, and when the changeable zone is softer than the hitting face, the vibration is reduced and the travel direction of the golf ball is controlled by the golf club head to facilitate a user controlling the travel direction the golf ball.

Problems solved by technology

However, the whole part of the hitting face of the golf club head has the same hardness so that the hardness of the hitting face of the golf club head cannot be changed, thereby decreasing the versatility of the golf club head.

Abstract

A golf club head includes a hitting face and a changeable zone formed on a surface of the hitting face and having a physical feature different from that of the hitting face. Thus, all part or partial of the changeable zone of the hitting face has a hardness different from that of the hitting face, so that when the changeable zone is harder than the hitting face, the golf club head provides a greater hitting force on the golf ball due to the greater hardness of the changeable zone to increase the travel distance of the golf ball, and when the changeable zone is softer than the hitting face, the travel direction of the golf ball is controlled by the golf club head to facilitate a user controlling the travel direction the golf ball.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a golf club head and, more particularly, to a golf club head and a method for making the golf club head.[0003]2. Description of the Related Art[0004]A conventional golf club head has a hitting face to hit a golf ball so as to move the golf ball during a period of distance. When the hitting face of the golf club head has a greater hardness, the hitting face of the golf club head provides a greater hitting force on the golf ball so as to increase the travel distance of the golf ball. On the contrary, when the hitting face of the golf club head has a smaller hardness, the contact time between the hitting face of the golf club head and the golf ball is increased so that the travel direction of the golf ball is controlled by the golf club head to facilitate a user controlling the travel direction the golf ball. However, the whole part of the hitting face of the golf club head has the same har...
