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 forging blank for a golf club head, the forging blank being made by casting and comprising: 
 at least one bending portion having a first end and a second end;    a club head portion extending from the first end of said at least one bending portion; and    a hosel portion extending from the second end of said at least one bending portion.    
   
   
       2 . The forging blank for a golf club head as claimed in  claim 1 , wherein each of the club head portion and the hosel portion has a substantially circular section.  
   
   
       3 . The forging blank for a golf club head as claimed in  claim 1 , wherein the club head portion of the forging blank has a sectional area greater than that of the hosel portion, the club head portion of the forging blank being forged to form a body of a golf club head, the body having a striking face.  
   
   
       4 . The forging blank for a golf club head as claimed in  claim 1 , wherein the club head portion of the forging blank has a sectional area smaller than that of the hosel portion, the club head portion of the forging blank being forged to form a striking portion of a golf club head, further including a weight member bonded to a rear side of the striking portion to form a body of the golf club head.  
   
   
       5 . The forging blank for a golf club head as claimed in  claim 1 , wherein the forging blank is made of one of a Fe—Mn—Al alloy, an AISI 4130 steel, and an AISI 8620 steel.
