Description

Preparation method and application of golf club head striking plate Technical Field The invention relates to the technical field of golf club head processing, in particular to a preparation method and application of a golf club head striking plate. Background The golf club mainly comprises a club body and a club head, wherein a club head striking panel is arranged on the club head, and the club head striking panel is a striking part contacted with the golf ball. In the related art, a golf club head striking plate is generally manufactured by adding a plastic back-off or bonding two pieces of finished plastic on a metal surface. However, adding plastic back-off on the metal surface can change the metal structure, reduce the metal strength and affect the resilience force, and the golf club head striking panel obtained by directly bonding two pieces of finished plastic has poor firmness and cannot ensure the thickness and flatness after bonding. The golf club head striking panels manufactured in the two modes are easy to cause unpredictable risks during striking, so that the striking effect is poor. Disclosure of Invention The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, the invention provides a preparation method of a golf club head striking plate, which can effectively ensure the strength, the firmness and the flatness of the golf club head striking plate.
