Method for Producing a Contact Face of a Head of a Golf Club

Abstract

A method for producing a face plate of a golf club head includes preparing a plate material to be processed, with the plate material including a first surface and a second surface opposite to the first surface; pressing and shaping the plate material at least one time by using at least one mold, forming an uneven thickness structure on the first surface of the plate material; and milling the second surface obtained from shaping to form a striking face, obtaining a face plate for a golf club head. The method for producing a face plate of a golf club head includes forming the uneven thickness structure on the first surface of the face plate and then milling and modifying the second surface of the face plate, significantly reducing the waste material of the plate material to be milled and removed. The cutter wear rate of the milling machine is reduced, and the processing time is shortened, saving production costs and increasing yield.

1 . A method for producing a face plate of a golf club head comprising:
 preparing a plate material including a first surface and a second surface opposite to the first surface to be processed;   pressing and shaping the plate material at least one time by using a mold;   forming uneven thickness structure on the first surface of the plate material; and   milling the second surface to form a striking face and a face plate for a golf club head.   
     
     
         2 . The method for producing a face plate of a golf club head according to  claim 1 , wherein pressing and shaping the plate material comprises:
 pressing and shaping the plate material by using the mold with a simple curved face; and   pressing and shaping the plate material by using another mold with a more precisely curved face.   
     
     
         3 . The method for producing a face plate of a golf club head according to  claim 1  further comprising shaping the plate material by a further mold with a curvature and shaping the striking face to an arcuate shape, after milling the second surface. 
     
     
         4 . The method for producing a face plate of a golf club head according to  claim 3 , further comprising cleaning the first and second surfaces of the plate material by sand-blasting on the first and second surfaces of the plate material and removing oxides and/or impurities from the first and second surfaces of the plate material. 
     
     
         5 . The method for producing a face plate of a golf club head according to  claim 3 , wherein shaping the striking face to the arcuate shape comprises shaping the striking face with a radius of curvature of 160 mm-600 mm. 
     
     
         6 . The method for producing a face plate of a golf club head according to  claim 1  further comprising forming an anti-oxidation layer on each surface of the plate material before pressing and shaping the plate material. 
     
     
         7 . The method for producing a face plate of a golf club head according to  claim 3 , further comprising forming an anti-oxidation layer on each surface of the plate material before shaping the plate material. 
     
     
         8 . The method for producing a face plate of a golf club head according to  claim 3 , wherein shaping the striking face comprises shaping the striking face with a radius of curvature of 160 mm-600 mm. 
     
     
         9 . The method for producing a face plate of a golf club head according to  claim 3 , wherein shaping the plate material by the further mold with the curvature comprises:
 pre-molding the further mold with a curvature having a radius of curvature of 160 mm-600 mm; and   shaping the plate material by the further mold with the curvature having the radius of curvature of 160 mm-600 mm.   
     
     
         10 . The method for producing a face plate of a golf club head according to  claim 3 , wherein shaping the plate material by the further mold comprises shaping the plate with the further mold with the curvature of a radius of curvature of 160 mm-600 mm.
