What important role is extrusion in aluminum profile processing?

The principle of aluminum profile extrusion

Aluminum profile extrusion is a plastic machining method that exerts external force on the metal blank placed in the container (extrude cylinder) to flow out of a specific die hole to obtain the desired section shape and size.

1. The extrusion used in aluminum processing is more malleable than by other processing methods such as rolling or forging. For some materials that must be rolled or forged for processing, such as 7075 alloys, it is also necessary to first squeeze the billet, can improve the structure to improve plasticity.

2. The extrusion not only can make the profile cross-section become different shapes, but also according to the mold of different more complex cross-sectional plane, increase the efficiency of use, reduce the cost of products, improve economic efficiency.

3. The extrusion processing flexibility is large, different molds extruded out of the profiles are not the same.

4. The extruded product accuracy is very high, the higher the mold quality, the greater the accuracy, the lower the loss.

5. The extruded aluminum alloy products are stronger and perform better than other aluminum alloy products.
