Aluminium is a metal that is silver white in appearance and is found in abundance in earth’s crust. Properties like high strength, light weight, corrosion resistance and cheap price make it one of the most in-demand metal in industrial world. What Aluminium Extrusion means? However, it’s not aluminium but aluminium extrusions that are most useful in the industrial world. Aluminium Extrusion in Wikipedia is defined as: A process used to create objects of a fixed, cross-sectional profile. Ability to create complex cross sections and working with brittle materials as they are subjected to only compressive and shear stress are the two main advantages of extrusion over other processes. It also provides excellent surface finish to the finished parts enhancing the appearance significantly. Aluminium is one third the density and rigidity of steel allowing it to be bent into various shapes and casts without compromising on strength and stability. Aluminium Extrusion Process For making aluminium extrusions, first the design is created for making the die cast. A good design can go a long way in making an extrusion that is high in quality, provides maximum utility and uses minimum alloy material. To make useful and practical die design, die cast engineers and company engineers should work together. After die casting is done, extrusion is carried out either by hot chamber or cold chamber process. In hot chamber extrusion, the material is heated before it is loaded into the chamber where the die is already placed. To push the material out of the die, pressure is applied. For prevention of formation of oxides in extrusion, liquid nitrogen is added. Cold extrusion is done at room temperature. Here also pressure is applied for pushing material out of the die cast. This process gives faster and stronger extrusion and better surface finish compared to hot extrusion process. Once the extrusion is ready and cooled off (in case of hot chamber process), it is brought to the table and cut into desired lengths. Finally, hardening and ageing of aluminium is carried out by heating it in ageing ovens. What are the Benefits of Aluminium Extrusion Aluminium extrusions have no welded joints, and are therefore stronger and can be moved around with ease. This also makes the assembly of extrusions simple and straight forward. Extrusions have a smooth surface finish and make for an attractive design and also eliminate the need for paint. The extrusions have multiple usages in automotive, retail, construction, display, stage setting, marquees and many other sectors. Vendors of Aluminium Extrusion Today, many companies across the world make aluminium extrusions. However, care should be taken to go for a manufacturer who understands the specialized skills required for the process. A well-designed die cast can reduce its cost and increase utility of extrusion. In addition, using right combination of alloys increases utility and improves productivity of machinery where it is placed. China is fast becoming a major hub for aluminium extrusion manufacturers. Renowned names like P&A International have set up advanced facilities for aluminium extrusions and die casting in China and cater to the requirements of industries all across the globe. Being in China allows them to provide high quality of extrusions at affordable prices. Aluminium extrusion has changed the way humans interact with metals. When considering vendors for extrusion ensure that, they have the expertise and the team to provide true value extrusions.
