Forging blank for a golf club head

Abstract

A forging blank for a golf club head is made by casting and includes at least one bending portion, a club head portion extending from an end of the bending portion, and a hosel portion extending from the other end of the bending portion. The angled bending portion of the forging blank reduces the deformation of the forging blank during a forging step that fills cinder holes in the forging blank. A golf club head can be manufactured with fewer forging molds without sacrificing the structure of the golf club head.

1 . A manufacturing method for a golf club head comprising the steps of: 
 forming a roughly shaped club head blank to have a bent portion in a casting procedure, said bent portion having a first end and a second end; and    shaping the club head blank for form a finished golf club head after the step of forming, the shaping being in a forging procedure.    
   
   
       2 . The manufacturing method for a golf club head as recited in  claim 1 , wherein the step of forming includes the roughly shaped club head blank having a club head portion extended from a first end of the bent portion.  
   
   
       3 . The manufacturing method for a golf head as recited in  claim 2 , wherein the club head portion has a substantially circular section.  
   
   
       4 . The manufacturing method for a golf head as recited in  claim 1 , wherein the roughly shaped club head blank includes a hosel portion extended from the second end of the bent portion.  
   
   
       5 . The manufacturing method for a golf head as recited in  claim 4 , wherein the hosel portion has a substantially circular section.
