Aluminum Extrusion is a metal forming process used for mass production of aluminum products with constant
cross section profiles such as rods, tubes, beams, wires, multi-porting tubes etc. The most commonly and widely
practiced type of extrusion in the industry today is the direct extrusion process, also known as the billet on billet
extrusion. In the direct extrusion process the hot aluminum billet is pushed through the profile opening of a die by
the ram in a hydraulic press with a force typically in the range of 1000-3500 ton (See Fig 1).
