The extrusion process is a metal-forming, high production volume process that uses continuous cast billet that has had the external diameter machined to remove oxides and other casting impurities. During the extrusion process, long sections are produced as a heated billet of metal is pushed through a die. The shape of the section produced is determined by the opening in the die. With Extrusion, there are high forces applied to form the metal whilst it is heated to a plastic state, resulting in product with superior grain structure and mechanical properties (similar to forged parts). Extrusions usually have an excellent surface finish and relatively fine dimensional tolerances.
