Clubface of a golf club and method for fabricating the same

Abstract

A manufacturing method of a clubface of a golf club reduces the amount of the metallic material used and enhances production. The manufacturing method includes the following steps: a metal powder and a binder are mixed to form a mixture; the mixture is shaped by a clubface mold to form a primary clubface; the primary clubface is then heated to a sintering temperature of the metal powder to form a clubface, before the clubface is finally compacted to make it stronger and increase the clubface's density.

1 . A manufacturing method of a clubface of a golf club, comprising: 
 mixing a metal powder and a binder to form a mixture;    shaping said mixture via a clubface mold to form a primary clubface;    heating said primary clubface to a sintering temperature of said metal powder to form a clubface; and    compacting said clubface.    
     
     
         2 . The manufacturing method of a clubface of a golf club as in  claim 1 , wherein said metal powder is titanium or a titanium alloy.  
     
     
         3 . The manufacturing method of a clubface of a golf club as in  claim 1 , wherein said binder is a macromolecule binder or an organic binder.  
     
     
         4 . The manufacturing method of a clubface of a golf club as in  claim 1 , wherein said mixing step comprises a step of providing a stirring machine for mixing and compressing said mixture.  
     
     
         5 . The manufacturing method of a clubface of a golf club as in  claim 1 , wherein said shaping step comprises a step of preheating said mixture to a point where the mixture takes on the characteristics of a fluid.  
     
     
         6 . The manufacturing method of a clubface of a golf club as in  claim 5 , further comprising a step of providing an injection molding machine to inject said mixture into said clubface mold.  
     
     
         7 . The manufacturing method of a clubface of a golf club as in  claim 1 , further comprising a step of dehydrating said binder in said primary clubface during the step of heating said primary clubface.  
     
     
         8 . The manufacturing method of a clubface of a golf club as in claim  1 , wherein said heating step further comprises a step of providing an ore-sintering furnace to sinter said primary clubface during the step of heating said primary clubface.  
     
     
         9 . The manufacturing method of a clubface of a golf club as in  claim 8 , further comprising a step of aerating a protective air into said ore-sintering furnace.  
     
     
         10 . The manufacturing method of a clubface of a golf club as in  claim 1 , wherein a range of said sintering temperature is two thirds of a melting point of said metal powder up to said melting point of said metal powder.  
     
     
         11 . A clubface a golf club produced according to the method of  claim 1 , formed by injection molded metal powder, comprising: 
 a main portion; and    a curved striking-surface, formed on a top surface of said main portion.    
     
     
         12 . The clubface of a golf club as in  claim 11 , wherein said curved striking-surface is formed with a plurality of protrusions.
