Extrusion allows even complex shapes of aluminium profiles to be manufactured. It is what makes this process so powerful.

The method
When manufacturing aluminium profiles, a billet heated to the forming temperature of approx. 500 °C­ is pushed through a mould with an extrusion die. ­A recipient encloses the billet. The outer shape of the extruded profile is determined by the mould.

Mandrels shaped in various ways make 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 stability.
