Extrusion is the process, in which aluminum billet, with large force provided by the press, takes the shape of the mold by passing through the steel molds.
Aluminum extrusion is conducted in a hot environment. Billets are heated at 420-520 °C, molds should be heated to 450 °C and the profile temperature coming out of the mold is 500 °C. Profile is cooled upon leaving extrusion, cold stretching is carried out and is cut in the desired lengths. Then profiles are treated with heat in order to gain strength. During this process, the profiles are held at 185 °C for five hours.
Our factory has 8 extrusion pres lines with different strength and sizes, that varies between 6-7-8-10 inch, in order to meet profile production demands of different sizes. With the production capacity of 70,000 tons annually, we can manufacture EN AW 1050, 1070, 6060, 6063, 6463-6005 alloys, as well as special alloys such as EN AW 6082.
A wide range of aluminium profile products for the purposes of various sectors and uses, are carried out in our extrusion lines.
