The aluminum extrusion process is to heat the aluminum to a malleable state, usually between 350 and 500 Celsius degrees, depending on the alloy type. The heated aluminum billet is then placed in a chamber and high pressure is applied using a hydraulic press, forcing the aluminum through a specially designed mold, which determines the final shape of the extrusion. As the material exits the mold, it will cool and solidify to maintain the required shape. The extruded aluminum can be further machined, such as cut, CNC machined or polished to meet specific application requirements. This process is highly efficient and can produce complex shapes with excellent precision and surface quality, making aluminum extrusion ideal for the mass production of structural parts, frames, housings, radiators and other parts.
