Extrusion Process


The principle of extrusion is simple: 

A heated billet is pressed through a die with great force and the finished profile emerges from the die. Cooling takes place immediately, by air or water. To ensure that the profiles are straight, the profiles are stretched after cooling. At the same time, they are checked to ensure that all key functional dimensions are correct and that the surface quality is as desired. The profiles are then cut to the appropriate length. The material is then subjected to an appropriate heat treatment to bring it to its required permanent level of strength.
