Method for Manufacturing a Striking Faceplate of a Golf Club Head

Abstract

A method for manufacturing a striking faceplate of a golf club head is disclosed in the present invention including the steps of preparing a plate material having an original thickness of 2-7 mm, where the plate material comprises a first surface and a second surface opposite to the first surface, and the first surface has a forming area and a peripheral area surrounding the forming area; pressing and shaping the plate material to form an uneven thickness structure at the forming area, where a maximal thickness is formed between the first surface and the second surface of the plate material, and the maximal thickness is larger than the original thickness of the plate material; and milling the second surface of the plate material obtained from the pressing and shaping step to form a striking face, where the weight of the plate material obtained from the milling step is 30-65% of the weight of the plate material of the preparing step.

What is claimed is: 
     
         1 . A method for manufacturing a striking faceplate of a golf club head, comprising the steps of:
 preparing a plate material having an original thickness of 2-7 mm, wherein the plate material comprises a first surface and a second surface opposite to the first surface, and wherein the first surface has a forming area and a peripheral area surrounding the forming area;   pressing and shaping the plate material to form an uneven thickness structure at the forming area, wherein a maximal thickness is formed between the first surface and the second surface of the plate material, and wherein the maximal thickness is larger than the original thickness of the plate material; and   milling the second surface of the plate material obtained from the pressing and shaping step to form a striking face, wherein the weight of the plate material obtained from the milling step is 30-65% of the weight of the plate material of the preparing step.   
     
     
         2 . The method for manufacturing the striking faceplate of the golf club head as claimed in  claim 1 , wherein the maximal thickness is 1.15-1.3 times of the original thickness. 
     
     
         3 . The method for manufacturing the striking faceplate of the golf club head as claimed in  claim 1 , wherein the pressing and shaping step further comprises arching the plate material, wherein the milling step further comprises milling the second face of the plate material to form the striking face as an arcuate shape having a radius of curvature of 160-600 mm, and wherein a center of curvature of the striking face is located at a side of the plate material adjacent to the first surface. 
     
     
         4 . The method for manufacturing the striking faceplate of the golf club head as claimed in  claim 1 , wherein the plate material is made of stainless steel, and wherein the original thickness and the maximal thickness are 2 mm and 2.3 mm, respectively. 
     
     
         5 . The method for manufacturing the striking faceplate of the golf club head as claimed in  claim 1 , wherein the plate material is made of Ti-alloy, and wherein the original thickness and the maximal thickness are 3 mm and 3.5 mm, respectively. 
     
     
         6 . The method for manufacturing the striking faceplate of the golf club head as claimed in  claim 1 , wherein the plate material is made of Ti-alloy, and wherein the original thickness and the maximal thickness are 3.5 mm and 4 mm, respectively. 
     
     
         7 . The method for manufacturing the striking faceplate of the golf club head as claimed in  claim 1 , wherein the plate material is made of Ti-alloy, and wherein the original thickness and the maximal thickness are 4 mm and 5 mm, respectively. 
     
     
         8 . The method for manufacturing the striking faceplate of the golf club head as claimed in  claim 1 , wherein the plate material is made of Ti-alloy, and wherein the original thickness and the maximal thickness are 5 mm and 6.2 mm, respectively. 
     
     
         9 . The method for manufacturing the striking faceplate of the golf club head as claimed in  claim 1 , wherein the plate material is made of Ti-alloy, and wherein the original thickness and the maximal thickness are 6 mm and 7.6 mm, respectively. 
     
     
         10 . The method for manufacturing the striking faceplate of the golf club head as claimed in  claim 1 , wherein the plate material is made of Ti-alloy, and wherein the original thickness and the maximal thickness are 7 mm and 9.1 mm, respectively.
