In extrusion, a billet of the starting material is heated to forming temperature and placed into a pressing cylinder, where an extrusion punch presses the material through a die. This can produce a strand up to 60 m long. This process places great mechanical and thermal requirements on the extrusion equipment, such as dies, liners, stems, and pressing discs. 

For that reason, this equipment must be made of special materials that have a high heat checking resistance, thermal strength, and durability and that are resistant to erosion and high temperature corrosion.

For pressing heavy metals, we offer the following materials:
