Cold-forging is a manufacturing process that uses 100% of the raw material — metal wire — to form the final part.
The part is created through the deformation of this wire: it is struck several times, across multiple stations, without any material loss.
The slug — the cut wire — is formed within successive dies. Depending on the machine, there may be between 3 and 6 or 7 stations, corresponding to the number of times the part is struck.
The final part produced by cold heading is called a “blank.”

Which raw materials can be used?
Steel, copper, aluminum, and brass wire are commonly used.
It is also possible to produce simple stainless steel parts. However, when the part becomes complex, an additional heating station must be added to the machine.
To provide production finishes, several options are available, such as thread rolling.
