Extrusion allows even complex shapes of aluminum profiles to be manufactured. It is what makes this process so powerful. When manufacturing aluminum profiles, a billet is heated to the forming temperature of approx. 500 °C is pushed through a mold with an extrusion die. A recipient encloses the billet. The outer shape of the extruded profile is determined by the mold.

Mandrels are shaped in various ways making the production of hollow spaces and multi-chamber profiles possible as well. The extruded profiles of lengths up to ­55 meters are then stretched, sawed to manufacturing lengths, and then generally aged artificially in order to increase strength and stability.
