INEXAL, S.L. is dedicated to the first transformation of aluminum by extrusion. The aluminum extrusion process involves applying pressure to the aluminum cylinder (billet), passing to a mold (die) to achieve the desired shape. Each type of profile has its matrix and that matrix determines its shape. The billet is heated to facilitate its passage through the matrix, and it is introduced into the press. When extruded profiles exit the press through the matrix, they slide on a bench where they are cooled with air or water, depending on its size and shape, and the characteristics of the alloy involved and properties required. Then, they are stretched to obtain aluminum profiles straight and eliminate any tension in the material. Afterwards, they are cut into suitable lengths and artificially aged to achieve adequate strength.
