Aluminum Extrusion Cnc Machining Parts?are useful for electronics, medical equipment, industrial manufacturing, household appliances, LED lighting and military industries. Aluminum extrusion is a technology used to transform aluminum alloy into object with definite cross-section profile, which can be widely used in various applications. The extrusion process makes full use of the unique combination of physical properties of aluminum. Its ductility makes it easy to process and cast, while aluminum is one third of the density and rigidity of steel. Therefore, the product has strength and stability, especially when it is alloyed with other metals.
Our Aluminum Extrusion Cnc Machining Parts are well received by many people. The advantage of Aluminum extrusion is that it can flexibly create multiple cross sections, such as T-shaped slot, U-shaped slot, I-shaped slot, L-shaped slot, circular slot, square slot, etc. Another advantage of this method is that it is relatively cost-effective in batch production, because it can shorten the delivery time.?We can provide excellent extrusion tools and the best extrusion profile.

The Process of Aluminum Extrusion consists of the following steps
1.After designing and creating the shape of the die, a cylindrical billet of aluminum alloy is heated to 800°F-925°F.
2.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.
3.Substantial pressure is applied to a dummy block using a ram, which pushes the aluminum 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 aluminum extrusion.
6.When the cooling is completed, the extruded aluminum 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 aluminum by speeding the aging process.
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 aluminum’s finish. This may include aluminum anodizing or painting.
Usually, aluminum heat sink is designed with different lengths, noise levels, Speeds, widths, styles, height and weight, and the extruded heat sink is Typically made of aluminum alloys as 6061 and 6063. The most popular extruded Aluminum heat sink is designed with a flat aluminum base with vertical radiating Fins for increased surface area, thus providing better heat dissipation Performance.
