Extrusion is a process of shaping a mass, bringing them out from an opening profiles for elaborate and complicated design. In the case of the aluminium extrusion, is carried out with alloys such as aluminium 6063-T5, 6063-T6, 6061-T6, 6005-T5, etc. Aluminium may be of first use, and also recycled.
The aluminium extrusion process consists of three phases.
Preheat
From a billet aluminium, primary or secondary, it starts casting parts up to 7 meters in length.
Extrusion
Aluminium billet, previously preheated and through an array, is passed to a high pressure between 1600 and 6500 tons. The opening of the matrix corresponds to the transverse profile extrusion, and has the desired pattern.
Cool down and stretch
When the profile leaves the press, this piece is cooled by air or water. Were stretched and cut into appropriate lengths
