Cold forming / cold extrusion

When it comes to large quantities with precise production and the best possible cost efficiency, cold forming / cold extrusion is the ideal alternative to classic turned part production for screws, nuts, bolts or formed parts.

Cold forming / cold extrusion is a part of solid forming in which the material is enclosed in a pressing tool well below the recrystallization temperature and brought to flow and into its desired shape under the influence of high force. After the elastic recovery of the material, a plastic deformation remains due to the abrupt termination of the application of force, which ultimately results in your desired finished part.

In some cases, complex component geometries cannot be produced by multi-stage forming alone. These parts require mechanical reworking, such as turning, milling, grinding, etc., in order to achieve your perfect final geometry.

Numerous materials such as structural steels, heat-treatable steels, case-hardening steels, stainless steels, high-temperature steels or even aluminum and copper are suitable for cold forming/ cold extrusion.

Cold forming parts / cold extruded parts - economical precision parts

Rising raw material and energy prices and general cost pressure demand economical production processes. The abrupt forming can achieve shorter production times and produce large quantities more economically while using the same amount of material.

The result is material-saving and cost-reduced production with excellent surface qualities and high dimensional accuracy of your desired components.
