The Process of Aluminium Fabrication

Aluminium Fabrication Process

Aluminium products have an essential role to play in the everyday lives of people. This is mainly because of its lightweight property that comes with outstanding durability. However, the process of manufacturing aluminium is not as easy as throwing it in the trash. Before aluminium is made ready for household use, it has to go through harsh techniques that involve a series of heating and purification. Browse through following steps to know more about aluminium fabrication process 

Refining and smelting are the two methods that give a definite answer to a question –

What is the Aluminium Fabrication Process  

The refining process involves mixing of bauxite with caustic soda. The mixture is crushed and processed to create a slurry containing ore particles. Under the next step, the slurry has to pass through an extreme heat and heavy pressure which helps to dissolve the aluminium compound. The liquid is then filtered in the tank where impurities are easily settled at the bottom and the primary solution is pumped through the filters.  


The process of smelting is trickier than other processes involved in the fabrication of aluminium.  In this method, the aluminium solution is exposed to electric current thereby allowing oxygen and aluminium particles to separate very quickly. The small molecules of oxygen are attracted towards carbon rod that results in the formation of carbon dioxide. On the other hand, the fresh and refined aluminium particles get settled at the bottom of the pot.  

One of the important objectives of manufacturing companies is to gain top quality aluminium from different types of material. The source mainly involves raw aluminium as well as recycled materials supplied from various production plants. To achieve the finished product as per specification is given by customers, there are several tricky processes involved in the fabrication of aluminium. Computer Numerical Control (CNC) machining is a useful technique that helps to mould and cut the aluminium in almost any shape according to the dimensions entered into the software. This technique is beneficial to produce complicated engine equipment and aircraft parts that demand high precision.  

The technique of cold pressing lets aluminium to get any particular shape of your choice. The process in which aluminium slug is moulded into the desired form by applying extreme pressure with the help of hydraulic. The technique is followed when metal is in a cool state and this is the reason why it is also known as cool stamping. 

When it comes to producing aluminium in complex form, aside from getting a  the method of tapping and drilling is highly effective. The metal is shaped into the microns of desired dimensions and the process is usually controlled via a computerised system. The parts which are manufactured using this technique mainly involve tyre rims, automotive tools, and camshafts. Most of the by-products achieved in the fabrication of aluminium are also used in industries such as ceramics and detergent.  

On the virtue of constant evolution observed in the manufacturing industry, the modern process of aluminium fabrication is more of an art rather than a taxing job. Today, most of the highly advanced equipment and machinery available in the industry that made few impossible things possible with minimum efforts.
