Aluminum Die Casting: A Comprehensive Guide on Die-Cast Aluminum Process

If you’re designing aluminum parts, it’s important to consider the manufacturing process. Among all the processes of forming aluminum, aluminum die casting is the go-to solution.Get more news about Aluminum Die Casting Auto Parts,you can vist our website!

Aluminum is a lightweight alloy with high dimensional stability. So, aluminum die casting is a popular manufacturing process to create complex shapes and designs with a thin wall section. Therefore, they are a popular metal in various industries.

This article will help you understand the basics of the die-cast aluminum process. Let’s take a deeper look into the process.
What’s the Aluminum Die Casting Process?
Die casting aluminum is a manufacturing method to create metal parts. An aluminum bar should be heated and melted entirely at a high temperature and then forced into the pre-shaped mold cavity to create desired metal parts.

The aluminum die casting process uses the casting machine’s cold chamber. The reason for melting aluminum in a cold chamber machine is that the high molten aluminum temperature would damage the machine if the injection mechanism is submerged like the hot chamber process.
In the cold chamber machine, the melting pot is separated and the molten aluminum alloys then are ladled from the pot into the die under high pressure. After injecting the molten aluminum, it takes a while to solidify. Then, you need to separate the two halves parts of the mold to reveal the aluminum cast part.

The end product comes out with a smooth surface. Most of the time, the finished products don’t need minimal machining and move into the delivery stage quickly. Moreover, the die-cast mold is recycled to manufacture the same parts before it deteriorates. Therefore, aluminum die casting is an ideal manufacturing process for large-scale production. And that is why manufacturers prefer to die casting this and it is popular in various industries.
Aluminum casting has extensive surface finish options. The dimensional stability is another big advantage of the aluminum die casting process. Moreover, they are versatile, and you can use them for nearly any industry.

When preparing for aluminum alloy die casting, picking the right alloy is your first important task. Let us give you some ideas on different common die-cast aluminum alloy properties to assist you.

For example, the A390 alloy has a high hardness and excellent wear resistance, but the flexibility is lower than all other alloys. Consequently, they are appropriate for applications like automotive engine blocks.
