These processes include: rolling, drawing, forging, spinning, piercing and extrusion.
Regardless of whether aluminium has been found in its molten or solid form, the manufacturer will then pass it through either a hot working or cold working process to prepare it for their customers. When using the hot working process (the most popular of the two), a billet will be heated to a temperature of over 79 degrees Celsius, which will allow the aluminium to be easily distorted and placed into its desired shape.
The reason for the popularity of the hot working process over the cold working one can be fully realized when you compare aluminium extrusion to squeezing toothpaste out of its tube. It is much easier to extrude the metal when it is malleable, meaning that it must have been heated to a certain temperature.
Finally, the aluminium will pass through an extrusion and drawing process that runs almost parallel to each other. This is the final step in the whole extrusion process and is the step that gives the metal its entire shape. Deep drawing, for example, is used give the metal a cup, conical tapered, cylinder and seamless tube shape. For less curved shapes, Aluminium Windows Perth Prices the drawing process is skipped.
