Aluminium Die Casting – Efficient, Durable and Versatile

Metal die casting is a process that is being used in a number of industries for efficient and effective product manufacturing. This process involves melting a metal and forcing it to pass through cavities or chambers at high pressure and then allowed to cool. After the metal cools, it takes up the shape of the die cast. This method reduces time and effort required in manufacturing a number of products. Though a number of non-ferrous materials are used in die casting, aluminium is generally preferred in a range of applications.

There are many benefits of using aluminium die castings. First, this metal is lightweight and is highly corrosion resistant, which makes it suitable for use in a variety of applications. Moreover aluminium is strong, stiff, hard and has a high strength to wait ratio. All the features make it highly suitable for use in automobile part manufacturing. Its high thermal and electrical conductivity make aluminium a great choice for telecom and computing industries. These attributes also make this metal perfect for use in electrical housings and connectors. Above all, aluminium has good EMI and RFI shielding properties, so it is suitable for use in the manufacture of handheld devices. Plus, aluminium retains its strength even at very high temperatures. So, even if it is melted and then cooled, it will not lose its original attributes. All these features make this metal perfect for die casting.

There are basically two methods used for die casting - hot chamber or cold chamber. While die casting aluminium, the cold chamber method is preferred over the hot chamber method as aluminium may react with iron when it is heated to a very high temperature. In the high pressure aluminium die casting, a separate chamber is used to melt the metal. When the metal alloy reaches the molten stage, the required amount is slowly transferred into the cold chamber, and into the hydraulic piston. Using this technique, high number of casts with high-quality casts can be produced over time. Different types of aluminium alloys are used in various manufacturing processes. The most commonly used alloys are A380, 413 and 383.

High pressure aluminium die casting is a versatile technique that is not only efficient, but also allows manufacturers to design and create high-quality durable die casts.
