Method for Manufacturing a Cup-shaped Striking Faceplate of a Wood Golf Club Head

Abstract

A method for manufacturing a cup-shaped striking faceplate of a wood golf club head includes preparing a heat-compressing mold having a mold cavity, preparing a base plate having a first surface and a second surface opposite to the first surface, preparing a thermally expanding sheet, placing the base plate in the mold cavity by adhering the first surface of the base plate to an inner surface of the mold cavity, placing the thermally expanding sheet on the second surface of the base plate, and compressing the base plate and the thermally expanding sheet using the heat-compressing mold to form the base plate as the cup-shaped striking faceplate under heat compression. Thus, the cup-shaped striking faceplate is obtained. The cup-shaped striking faceplate includes a bottom wall and a lateral wall having a height of 5 to 40 mm.

         3 . The method for manufacturing the cup-shaped striking faceplate of the wood golf club head as claimed in  claim 2 , wherein a declined angle between the largest and smallest outer diameters of the lateral wall is equal to or smaller than 15°. 
     
     
         4 . The method for manufacturing the cup-shaped striking faceplate of the wood golf club head as claimed in  claim 2 , wherein the thermally expanding sheet has a thickness of 0.5 to 5 mm. 
     
     
         5 . The method for manufacturing the cup-shaped striking faceplate of the wood golf club head as claimed in  claim 2 , wherein the thermally expanding sheet has a Shore hardness value of 40 to 100. 
     
     
         6 . The method for manufacturing the cup-shaped striking faceplate of the wood golf club head as claimed in  claim 2 , wherein the size of the thermally expanding sheet is equal to or smaller than the size of the base plate. 
     
     
         7 . The method for manufacturing the cup-shaped striking faceplate of the wood golf club head as claimed in  claim 2 , wherein the base plate is a carbon fiber material. 
     
     
         8 . The method for manufacturing the cup-shaped striking faceplate of the wood golf club head as claimed in  claim 2 , wherein the base plate comprises a carbon fiber material and a metal sheet, wherein the metal sheet of the base plate is adhered to the mold cavity. 
     
     
         9 . The method for manufacturing the cup-shaped striking faceplate of the wood golf club head as claimed in  claim 8 , wherein the metal sheet is made of “6-4” type of titanium alloy. 
     
     
         10 . The method for manufacturing the cup-shaped striking faceplate of the wood golf club head as claimed in  claim 1 , wherein a declined angle between the largest and smallest outer diameters of the lateral wall is equal. to or smaller than 15°. 
     
     
         11 . The method for manufacturing the cup-shaped striking faceplate of the wood golf club head as claimed in  claim 1 , wherein the thermally expanding sheet has a thickness of 0.5 to 5 mm.
