Corrosionpedia Explains Cold Heading

The cold heading or cold forming process is a cost effective solution. The shape of the metal is altered to almost match the finished product under cold temperature conditions. Some industries prefer to perform cold heading procedures at ambient temperatures, although most perform it at cool temperature conditions according to the kind of metal used in the process and the strength of the machinery. There are three common techniques used during cold heading:

  • Forward extrusion
  • Backward extrusion
  • Upsetting

Some of the tools used during the cold heading process are:

  • Cold header
