ALUMINIUM EXTRUSION

What is aluminium extrusion?
Aluminium extrusion is a technique used to transform aluminium alloy into objects with a definitive cross-sectional profile for a wide range of uses. The extrusion process makes the most of aluminium’s unique combination of physical characteristics. Its malleability allows it to be easily machined and cast, and yet aluminium is one third the density and stiffness of steel so the resulting products offer strength and stability, particularly when alloyed with other metals.

The Process of Aluminium Extrusion
The process of aluminium extrusion consists of the following steps:
• After designing and creating the shape of the die, a cylindrical billet of aluminium alloy is heated to 800°F-925°F.
• The aluminium 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 aluminium 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 aluminium extrusion.
• When the cooling is completed, the extruded aluminium 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 aluminium by speeding the aging process.
