Method for Assembling Club Head and Shaft

Abstract

Disclosed is a method for assembling a club head and a shaft, comprising: an jointing step of jointing a blank element of club head and a blank element of shaft that are made of different materials to thus construct a blank element of golf club; a wrapping step of wrapping up the blank element of golf club with powder; and a constructing step of applying an isostatic pressing to the wrapped blank element of golf club to construct the blank element of club head, the blank element of shaft and the powder as a golf club.

What is claimed is: 
     
         1 . A method for assembling a club head and a shaft, comprising:
 a step of jointing a blank element of club head with a blank element of shaft that are made of different materials to construct a blank element of golf club;   a step of wrapping up the blank element of golf club with powder by used of a wrapping member; and   a step of constructing a golf club by applying an isostatic pressing to the wrapped up blank element of golf club to construct the blank element of club head, the blank element of shaft and the powder as a golf club.   
     
     
         2 . The method as claimed in  claim 1 , wherein the blank element of club head and the blank element of shaft are made of metals with different materials, alloys with different compositions, alloys with the same composition but with different ratios thereof, or metals/alloys made by different processes. 
     
     
         3 . The method as claimed in  claim 1 , wherein in the jointing step, the blank element of club head and the blank element of shaft are jointed by attaching their radial surfaces with each other or fastening with fastening portions with each other. 
     
     
         4 . The method as claimed in  claim 1 , wherein the wrapping step is processed by pre-forming the powder as an wrapped blank element, or by a vibration that fills the powder into the wrapping member. 
     
     
         5 . The method as claimed in  claim 1 , wherein the powder is a metallic powder. 
     
     
         6 . The method as claimed in  claim 1 , wherein the wrapping step further includes a sub-step of sealing that seals the wrapping member. 
     
     
         7 . The method as claimed in  claim 1 , wherein the wrapping member is made of a metallic material or a ceramic material. 
     
     
         8 . The method as claimed in  claim 1 , wherein the isostatic pressing is a hot isostatic pressing with a high temperature and a high pressure.
