Aluminum extrusion is the metal analogy to thermoplastic extrusion. A billet of aluminum is heated and then placed into a press that consists of a hydraulic ram, a barrel and a die. The hot aluminum is then forced out through the shaped orifice to create a part with a constant profile
.

Process Characteristics
Part Cost - low Tooling Cost - low to moderate Production Rate - high AL is lightweight compared to other metals Secondary machining is fairly easy Good tolerance capabilities with aluminum Can approach the tensile strength of steel Accepts a wide variety of finishes
