Cold heading

Cold heading has its origins in the work of nut and bolt making with the production of small parts. The cold heading process involves working the materials in a few hundredths of a second: a slug with an identical mass to the finished piece is sheared, then punched by several successive heads to obtain the final shape.

Advantages of cold heading:

  • no loss of material so the price of the finished part is not affected (unlike machining),
  • better mechanical performance of the part: cold heading maintains the structure of the material as it does not cut the fibres,
  • high manufacturing stroke rates: from 40 to 800 parts/minute,
  • suitable for mass production.
