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 2 of 6 inch 1250 tons, 1 of 7 inch 1650 tons, 2 of 8 inch 2700 tons and 1 of 10 inch 3500 tons, a total of 6 presses with different strength and size in order to meet profile production demands of different sizes. Our factory with the production capacity of 60,000 tons annually, 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.
