Cold Extrusion – Forging

Either through intense pressure or a combination of pressure and temperature, it is possible to fabricate complex components which are so precise, with such an excellent surface finish, that they can be used without any further processing.

In addition to (closed die) forging, in which the glowing hot workpiece is shaped as quickly as possible through hammer strikes, in cold extrusion, the material is caused to flow in a cold state and is formed by the construction of the moulds.

A particular advantage of this is the consistent part tolerance. Further advantages are the cold work hardening of the material, which improves the quality of the workpiece, and the relatively low material input.
Together with our clients, we attempt to find the optimal process for each application.
