Aluminum extrusion profiles are part of an amazing number of manufactured products and a wide assortment of construction projects. They are essential to the lightweight, strong and corrosion-resistant components required for glasswork, windows, and doors, heat sinks, mechanical parts, framing and for parts used in a broad variety of engines, electronic motors, and industrial equipment and robotics – even the manufacture of heavy equipment, trucks, and railroad cars. Aluminum extrusion profiles are also important in the production of many different rods, pipes, channels, and conduits in a wide range of sizes used by in a variety of industries. |

What is Aluminum Extrusion?
Aluminum extrusion is a technique used to transform aluminum alloy into objects with a definitive cross-sectional profile for a wide range of uses. The extrusion process makes most of the aluminum’s unique combination of physical characteristics. Its malleability allows it to be easily machined and cast, and yet aluminum is one third the density and stiffness of steel so the resulting products offer strength and stability, particularly when alloyed with other metals.
What is the process of Aluminum Extrusion?
The process of aluminum extrusion consists of the following steps:
- After designing and creating the shape of the die, a cylindrical billet of aluminum alloy is heated to 800°F-925°F.
- The aluminum billet is then transferred to a loader, where a lubricant is added to prevent it from sticking to the extrusion machine, the ram, or the handle.
- Substantial pressure is applied to a dummy block using a ram, which pushes the aluminum billet into the container, forcing it through the die.
- To avoid the formation of oxides, nitrogen in liquid or gaseous form is introduced and allowed to flow through the sections of the die. This creates an inert atmosphere and increases the life of the die.
- The extruded part passes onto a run-out table as an elongated piece that is now the same shape as the die opening. It is then pulled to the cooling table where fans cool the newly created aluminum extrusion.
- When the cooling is completed, the extruded aluminum is moved to a stretcher, for straightening and work hardening.
- The hardened extrusions are brought to the saw table and cut according to the required lengths.
- The final step is to treat the extrusions with heat in age ovens, which hardens the aluminum by speeding the aging process.
