Raw material requirements:
• Aluminium billet
• Aluminium extrusion machine
• Cooling technology
The process of aluminium extrusion consists of the following steps:
1. After designing and creating the shape of the die, a cylindrical billet of aluminium alloy is heated to 800°F-925°F.
2. 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.
3. Substantial pressure is applied to a dummy block using a ram, which pushes the aluminium billet into the container, forcing it through the die.
4. 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.
5. 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.
6. When the cooling is completed, the extruded aluminium is moved to a stretcher, for straightening and work hardening.
7. The hardened extrusions are brought to the saw table and cut according to the required lengths.
8. The final step is to treat the extrusions with heat in age ovens, which hardens the aluminium by speeding the aging process.
9. Additional complexities may be applied during this process to further customize the extruded parts. For example, to create hollow sections, pins or piercing mandrels are placed inside the die. After the extrusion process, a variety of options are available to adjust the colour, texture and brightness of the aluminium’s finish. This may include aluminium anodizing or painting.
