Die Casting with Aluminum: An In-Depth Guide to the Die Casting Process of Aluminum

What is the process of aluminum die casting?

A die casting aluminum component is a manufacturing technique that uses an aluminum bar that is heated and melted entirely at a high temperature and then forced into a pre-shaped cavity of the mold to form the desired metal part.

As in the hot chamber process, aluminum is melted in the cold chamber of the casting machine. This is because the high temperature of the molten aluminum would damage the injection mechanism in a hot chamber machine.

Cold chamber machines separate the melting pot from the die, which is then filled with molten aluminum alloys under high pressure. It takes a while for the aluminum to solidify after injection. To reveal the aluminum cast part, you need to separate the mold’s two halves.  

Most of the time, the finished products don’t require major machining and can be delivered quickly. Furthermore, die-cast molds can be recycled to manufacture the same parts before they deteriorate.

Therefore, aluminum die-casting is an ideal manufacturing process for manufacturing large volumes of aluminum. Because of this, aluminum die-casting has gained popularity in many industries and Aluminum Parts Manufacturer prefer to die-cast aluminum for large volumes of production.

Advantages of Aluminum Die-Casting

Die casting aluminum offers a number of surface finish options and dimensional stability. Additionally, they are versatile and can be used in nearly any industry.

The following are some of the benefits of aluminum casting:

  1. Tensile strength is good
  2. Surface finishes that are excellent
  3. Impurities and porosity are reduced
  4. Raw materials with low costs
  5. Precision in thickness (less than 1.5 thickness is achievable)
  6. Molecular structure ensures dimensional tolerance without microcracks
  7. Longevity
  8. Pressure and airtightness
  9. Complex parts can be produced
  10. Chemical and mechanical properties of many alloys to choose from

Designing Aluminum Die Casting Parts – 3 Factors to Consider

During the aluminum die casting process, manufacturers need to take some precautions.

Mold Design

The first big thing is the mold design. The mold needs to be efficient so that melted aluminum can be injected and built parts can be produced effortlessly. A parting line (the line that separates two halves of each mold) should be considered by the designer before finalizing the plan.

Wall Thickness

Additionally, you should consider the wall thickness of the parts. With automation technology and sophisticated machines, there is no minimum thickness level. However, it is best to choose a consistent thickness for better results.

The Location of Injection Point

Next, you should consider where the injection point is located. It is possible to add more than one injection point if there is any chance that the melted aluminum will solidify before reaching every crevice in the die. It also helps to create cavities.
