How does the aluminium extrusion process work?
A die is cast from the cross-section of the product you want to create. Then, a billet of aluminium is pushed through the die using a hydraulic ram, usually at an elevated temperature (hot aluminium extrusion). If the aluminium extrusion process is conducted at or below room temperature, it is considered cold extrusion. If the product needs to be hollow, most manufacturers use a hollow billet; however, since aluminium can be manipulated to some degree, it is also possible to reshape the material after the aluminium extrusion process is complete. The equipment required to conduct the aluminium extrusion process is not very complicated. A hydraulic ram and the materials necessary to create the die are all that is needed, and of course the billets of aluminium. A dummy block is also sometimes needed when using extrusion presses rather than dies. Rather than purchasing dies or extrusion presses, many business owners choose to hire aluminium extrusion manufacturers or suppliers to do the wo
