Aluminum Extrusion is the process of using a press to push hot aluminum through a permanent tool, known as a die, to form a shape with a desired cross section. Because this process only utilizes compression and shear stress, complex designs from brittle materials are possible. Almost any geometrical shape and length is possible. Some industries using extrusions are: automotive, architecture & construction, electronics, elevators, medical, lighting, solar, truck bodies, and general industrial uses. Dimensional tolerances can vary depending on design, length and wall thickness requirements, and are determined by individual extrusion.
Shapes - extrusions can take on virtually any geometrical shape. Including, but not limited to:
