Cold Headings

This process uses only cold workable metals, typically in wire form that is drawn through a mandrel to size and straightened.  It is then formed in a series of progressive dies upsetting features on the end portions of the blank. It is then cut off and often threaded in the same operation.  This process typically produces a near net shape workpiece, which means the final product is complete.   Sometimes requiring additional plating, heat treating, or machining.

-Close tolerances (+/-.002), net shape, minimal 

  scrap

-Low cost

-Rapid production rate        

-Continuous grain flow                        

-High strength        

-Reduced secondaries

-Thread rolling, knurling, and roll forming

-Heat treating, plating, assembly

-Ductile and crack resistant
