Processing Complete
Coil wire is cut into billets of a predetermined length.
A processing method to reduce the diameter of a material by pushing it into a mold that is thinner than the material.
A processing method that utilizes perforated dies to facilitate material displacement. It is used to form shapes wider than the original material diameter.
A processing method in which material is moved in the opposite direction of the force applied by the punch.
The completed part is ejected from the last die
High efficiency material utilization (high yield)
The high material utilization of cold forging allows for significant reductions in material waste (scrap) compared to machining for the same geometry.

Higher speed, more efficient production
Cold forming allows for high speed manufacturing (around 100 parts/minute) while still maintaining high precision and complex product geometries. No heating of the material is required.

Improved product strength by work hardening
Cold forming process design takes fiber flow lines (the crystal structure of metals) into account allowing for stronger more durable parts.

Cost reductions through customized manufacturing processes
If a customer design(toleranc es, geometry, number of components required, etc) is practical using cold forming, significant improvements in part unit cost and reduced process complexity are possible.
