Metals have been an indispensable part of our daily life—both ferrous and non-ferrous metals aid our industries. Aluminium is one of the most popular metals in the category.  The casting process for it is generally classified under Mould casting or Ingot (slab) casting. However,you can’t use aluminium directly after extraction. Depending upon the industry, aluminium has to be cast to make a final product. In short, aluminium casting is the pouring of molten aluminium into the desired moulds. It isn’t as simple as it sounds. There are various ways in which mould casting is done. Three methods are used and known more than the others. 

• Die casting : Die usually refers to a steel mould in this case. This process involves pressure. Die casting is done under high as well as low-pressure conditions depending on the manufacturer. Molten aluminium is poured into a steel mould by applying pressure. This method is usually adopted when there is a need for mass production. It delivers uniform products. This method demands the right machinery and infrastructure.
• Permanent mould casting : As the name suggests, a permanent mould is used in this case. A stable core is also present in the steel or other metal mould. Sometimes, if the core is impossible to remove after formation, a semi-permanent core is used. Permanent mould castings are chosen because the moulds made are more reliable than the other methods.
• Sand casting : This process involves a semi-permanent mould in the process. The cast is pressed into a unique sand mixture to make the mould. It aids in the secure replication of a casting. This is used to make small batches of products. It also comes in handy when intricate designs have to be copied. The process for making the mould is straightforward and easy compared to the other methods. The only downside is that the mould can’t be used for very long.

Aluminium casting is no doubt a powerful technique bearing an element of versatility in it.That’s the reason it is often used in manufacturing semi- or finished products having intricate shapes. The domain is continually developing to satisfy more specific needs of the users and to penetrate new markets.
