Aluminium Die Casting


Aluminium die casting is a remarkably affordable and reliable process that can produce parts of any size. In this blog post, I will provide you with more information about this great fabrication method and all you need to know.

What is Aluminium die casting?

Aluminium die casting is a metal casting process that uses molten aluminium. The liquid aluminium cools and hardens to form the desired shape, which can be used for many small precision castings from one pour.

How does the process work?

An injection molding machine injects molten aluminium under pressure into a silicone mold. After the metal has been injected, it is then left to cool for hours before being removed from the cavity and recycled again. All of this happens in an aluminium company like the aluminium die casting company in Malaysia, which specializes in die castings that are used by other companies around the world.

Benefits of die casting

  • Aluminium die casting is a low-cost manufacturing process that produces components in various shapes, sizes, and volumes at fast rates. A good example of this would be the bottle cap from your favorite soda brand – it’s likely been created with aluminium dies
  • Near-net shape castings reduce the need for secondary machining and can eliminate or minimize any internal features in a component, which makes them more cost-effective than other manufacturing methods.
  • The castings are hermetically sealed by liquid aluminium alloys, which protect them from wear and tear.
  • Aluminium is a lightweight, corrosion-resistant metal that can be used for many purposes. The metal is conductive and offers excellent heat transfer, while also allowing for low-cost production of custom parts due to its high level of automation in the process.
  • You can create multiple pieces of aluminium die castings in just one production cycle. Compared to other methods, this means faster processing time and lower cost per unit for the customer.
  • Aluminium die casting is not only environmentally friendly, but it also provides recycling and reusability benefits.

What materials are used for die casting?

The aluminium alloys that you’re most likely to find are molten salt, electric arc furnace, and intermediate purity. The first is the cheapest because it melts at room temperature; the second is for high-end applications where the pureness of metal matters more than cost (such as in aerospace); the third one has a middle ground – not too expensive but still good quality.

Types of aluminium die cast

Aluminium die-casting is a process that has been used for decades in the automotive industry. However, it’s not as simple as you might think. There are many different types of aluminium alloys and each one has its application to meet your demands.

Alumax D and Hypereutectic are two popular options that can be combined with other metals such as copper or steel depending on what type of durability you need from an alloying agent

How to choose the right material for die casting

The process of die casting starts with a metal alloy, typically an aluminium one. When the molten alloys are poured into the mold and allowed to cool down, they form inside it without damaging the part. This is when removed from its cavity after about 20 minutes in most cases, but depending on how complex or intricate your design is this may take longer or shorter.
