Extrusion is the process whereby objects of cross-sectional profile are created. The process involves a series of complex procedures. Aluminium extrusion is therefore, the process of taking aluminium alloys and shaping them into objects with a cross-sectional profile. Being one of the most abundant elements, it makes up about 8% percent of the earth crust. It has numerous properties such as being ductile and malleable, soft and lightweight. It can also be non-magnetic and has a shiny silvery appearance. Its lightweight nature allows it to be cast, drawn, and extruded.
The process of extruding it is quite complex and involves a number of steps, the first one being designing and creating the shape of die. After the completion of this, an alloy having a cylindrical shape is heated at high temperatures of between 800F and 925F after which it may be transferred to a loader. In order to prevent it from sticking to the extrusion machine, a lubricant is applied.
The next step involves the application of tremendous pressure onto a dummy block. This pressure is responsible for forcing the element into the die. When this element comes into contact with oxygen it tends to form oxides. In order to prevent this, nitrogen either in gaseous or liquid form is passed through sections of a die.
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.
