Aluminum is one of the most used metals in today's society - it can be found across a number of industries, such as construction and commercial, and in a number of applications, such as beverage cans and appliances. When choosing a manufacturer of aluminium extrusion for supplying the metal that you use in your workplace, however, it is important that you carefully consider which one will be best for your needs.
The manufacturer will begin by removing the aluminium from deep within the earth's crust (either as bauxite ore or feldspar). Often, the Bayer's method, Wohler's method or Hall Heroult method is chosen to remove the metal in its molten form. It is then hardened and moulded into whatever shape the manufacturer desires. When the aluminium is extracted from the earth in its solid form, it will be passed through a number of mechanical processes that are designed to give the metal its desired shape. 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 aluminum 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, the drawing process is skipped.
Once you are satisfied with the processes and methods utilized by a potential manufacturer of anodized aluminum, you can begin submitting your orders with them. If, after your first delivery, you are still satisfied with the manufacturer based on the promptness of the order being filled and the quality of the aluminium that you receive, you can continue the relationship.
