The creation of objects cross-sectional profile is referred to as extrusion. It usually involves pushing a material through a die with the desired shape. The deformation of an alloy by forcing it through a die using pressure to create a new shape is known as aluminium extrusion. The element is among the elements that are most abundant on earth coming in third after oxygen and silicon with a composition of about 8%. It has a number of properties like being soft, ductile, and malleable among other properties. Its amazing qualities allow for it to be cast, machined, drawn, and extruded. In addition, it also has a silvery look and a non-magnetic nature.
As earlier mentioned, the extrusion process is quite complex as it involves a series of procedures. The first step involves the design of shape of the die. One the desired shape has been created, an alloy of cylindrical shape is heated at temperatures of about 800F-925F. After this has been done, it may be then transferred onto a loader. A lubricant is then applied so as to avoid sticking onto the extrusion machine.
The second step involves application of pressure. A large amount of pressure is applied to a dummy block, which then forces the metal billet into the container and into the die. Nitrogen that is either in liquid or gaseous form is then induced through the sections of a die. This is done so as to prevent the formation of oxides.
A run-out table allows the extruded material to pass through as a piece that is now the same shape as the die. Cooling fans then cool the metal extrusion created. Once this process is complete, it may be moved to a stretcher where it might be straightened and hardened. They are then placed on the saw table where they are carefully cut into the desired lengths.
The final step involves the application of heat. Using heat treatments, the extrusions are brought into age ovens where hardening takes place. Depending on the colors or texture needed, adjustments can be performed here so as to get the desired finish. The process is widely used because this way various shapes and sizes of aluminium can be obtained.
This process has witnessed quite a number of changes most especially concerning growth and development. A series of new methods are being put into use so as to make the process more effective. The metal in itself is applied in many areas. Many items are made using the metal. These items may include household products like utensils, packaging containers, foils, watches, streetlight poles, and other numerous products.
It can be most preferred in the manufacturing industry because it has a low density and is also able to resist corrosion. Another great feature is that it does not ignite easily. For these reasons, many industries such as the transportation industry, aerospace as well as construction industries make use of this metal. In addition, it may also be used in the fabrication process of superconducting qubits due to its ability to conduct both thermal and electrical charges.
The metal is durable in addition to having an attractive appearance; this is why it is also widely used in making of communication gadgets such as smartphones among others.
