Cold extrusion features a massive forming process to produce both hollow and solid blanks in a multistage production process (multistage pressing).
The material is extruded there by application of a high pressure. An upper die presses the blank through a forming and cross-section-reduced die orifice - the mold.

ESKA has espacially focused on the manufacture with four - to six-stage presses and, therefore, is able to make products with complicated geometry and a high forming degree.
Advantages of cold extrusion process: - high dimensional stability
- excellent surface finish
- continuous fiber flow line thanks to forming
- efficient process for mass production
