Aluminium die casting is an economical and reliable process for producing small to medium-sized metal parts. It has several advantages over other casting processes, such as reduced setup costs, good dimensional stability, and the ability to make near-net shapes.
This article will provide you with more information about aluminium die casting so that you can determine if it’s right for your application.
What is Aluminium die casting?
Aluminium die casting is a metal casting process that uses an aluminium alloy. The molten aluminium is poured into the mound, which then cools and hardens to form the required shape. A large number of small precision castings can be made from one pour.
How does it work?
An injection molding machine injects by injecting the molten aluminium under pressure into a mold cavity. After this, a runner system spreads the liquid metal around the mound and it is then left to cool for a while. All of this is done in an aluminium company like the famous aluminium die casting company in Malaysia.
What are some advantages of Aluminium die casting?
· Production of near-net-shape castings. This reduces the need for secondary machining because you can reduce or eliminate any internal features in the component.
· Aluminium die casting is less expensive than other methods of manufacturing cast components such as sand and permanent mold processes.
· Durability is another advantage because the castings are hermetically sealed by liquid aluminium alloys.
· Corrosion-resistant and lightweight are two other benefits of using Aluminium die casting.
· Conductivity and excellent heat transfer are additional benefits of using Aluminium die casting.
· The processing time for aluminium dies castings are much faster than other methods because you can produce multiple parts at a time with just one production cycle.
· Recycling and reusability are also two other benefits of using Aluminium die casting.
What materials can be used for Aluminium die casting?
The aluminium alloy that you’re going to find the most common is a molten salt aluminium alloy because it’s very low in cost and it melts at room temperature. The second one would be an electric arc furnace alloy. The third one would be an intermediate-purity aluminium alloy, and those are used for the high-end aerospace applications where you want to make sure that the material is pure enough.
How to choose the right material for die casting?
For starters, checking the cost is the first thing to do. If you’re making a lot of parts, the aluminium alloys are going to be much more economical and they can also have higher strength-to-weight ratios because aluminium has a lower density than steel.
How long does it take for die casting?
The process of die casting starts with a metal alloy, typically an aluminium alloy. The molten alloys are poured into the mold and allowed to cool so that they can be removed from the cavity without damaging the part. This takes about 20 minutes in most cases but depending on how complex or intricate your design is this may take longer or shorter.
Types of aluminium die cast
There are a lot of different types of aluminium die-cast and each one has an application in the automotive sector. The two most popular alloys, Alumax-D and Hypereutectic aluminium are used for everything from engine blocks to transmission housings to suspension parts. These high-strength alloys can be combined with other metals.
