An insight into Precision Aluminium Die Casting

Posted by sunainaram on September 1st, 2015

Casting is a manufacturing process by which a liquid material is usually poured into a mould, which contains a hollow cavity of the desired shape. The liquid metal is then allowed to solidify, so that it takes up the shape of the mould when it comes completely solid. The solidified part is known as a casting, which is ejected or broken out of the mould to complete the process.

Precision die casting has been used since in the ancient period, to make jewellery and other small products. In the recent years, however, this manufacturing technique is used for manufacture of automobile spare parts and electronic items. The best part of using aluminium die casting for manufacturing spare parts is that you can produce even the smallest of parts with the utmost precision. This manufacturing technique allows manufacturers to embed minute details into the cast design, which is reflected in the final product. Like for example, the logo of the company can be embedded in the cast design. When the molten metal solidifies, the logo is marked on the cast. So, the manufacturers don’t have to spend extra time and effort to add the company logo to the finished product. If all the details are meticulously noted when the cast is designed, then the manufacturer will be able save money on the entire production process.

Aluminium alloys are popularly used in most die casting techniques as it is easy to cast and offers durable results. Plus, aluminium is a non ferrous metal. The adoption of Aluminium die casting method comes with a bundle of benefits. Aluminium metal is a very light weight metal to cast, and it offers high dimensional stability for complex shapes and thin walls. It has good mechanical properties such as high thermal and electrical conductivity. Above all, it retains strength at high temperatures and it is also corrosion resistant.

Precision casting techniques have made manufacturing processes much easier than before. They are now widely used in a lot of manufacturing industries for faster and better production of products. Die casting technique is preferred by most manufacturers as it reduces metal wastage, which again adds to their profit levels. Scores of other alloys of zinc, lead, tin and other metals are also used in die casting. This versatile manufacturing technique has brought about a sea change in the production line of a number of components and spare parts.
