Aluminium extrusion is a technique that is brought to use in order 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. At 3E-PD, we are very well aware of its malleability which allows it to be easily machined and cast, which is why we use this property to the core in order to generate products of your liking, Moreover, aluminium is one-third the density and stiffness of steel, so the resulting products offer strength and stability too. When alloyed with other metals, you get a product of finest quality.
The Process of Aluminium 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 aluminium billet is then transferred to a loader in order to add a lubricant to prevent it from sticking to the extrusion machine.
- Substantial pressure is applied to a dummy block using a ram, thereby, forcing it through the die. To avoid the formation of oxides, nitrogen in liquid or gaseous form is added and allowed to flow through the sections of the die to increase the life of die.
- The extruded part passes onto a run-out table as an elongated piece that is now the same shape as the die opening. After cooling, the extruded aluminium is straightened and hardened. The hardened extrusions are brought to the saw table and cut according to the required lengths.
- Lastly, heating in age ovens hardens the aluminium by speeding the aging process.
