Aluminium extrusion is the process of aluminium forming. The aluminium extrusion process uses the original form of aluminium, which is called the aluminium billet of the aluminium ingot. The aluminium billet is preheated to a specified temperature at which the aluminium becomes soft and malleable, and then forced through a mould or die that is designed to shape and form the aluminium material to different aluminium profiles with desired cross-section shapes.
