What Is The Aluminium Extrusion Process?
Aluminium is one of the most popular metals in the world today. As a matter of fact, aluminium is the most abundant metal found on the earth’s crust. It is used for a variety of applications in the manufacturing industry. Aluminium is naturally found as bauxite and the metal can also be extracted from feldspar. The most popular extraction methods are Bayer’s method, Wohler’s method and the Hall Heroult process. Once the metal is extracted as a molten liquid, it can be solidified into any desired shape. However, this process is not easy and other fabrication methods have to be used. The non-technical term for the process that gives a proper shape to the aluminium metal is called shaping. If the extracted aluminium is in the form of a solid, mechanical working processes are made use of to give a proper shape to the metal. These processes include rolling, drawing, forging, spinning, piercing and extrusion. There are two types of mechanical working processes hot working and cold working. I
