Extrusion is a process that provides virtually unlimited opportunities for adapting product shapes. Costs are cut by using fewer components, which reduces the finishing process and simplifies assembly.

Extrusion is the introduction of aluminium into a container and forcing it at high pressure through the profiled opening of a die. The process actually begins with computer-aided design, which gives the profile its real added value. It is at this point that the shape details are defined to allow the quickest and most effective assembly with other parts and minimize fabrication time.

Low costs - The cost of dies is significantly lower than the tools used for conventional building materials and methods of production. The costs vary with the size and type of extrusion. Low die costs also make the extrusion technique interesting for the production of trials and prototypes.
