Extrusion allows even complex shapes of aluminium profiles to be manufactured.

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.
