The aluminium die casting process consists of several key stages, each crucial to ensuring high-quality parts are produced. The process begins with the creation of a mold and ends with post-processing activities that prepare the part for its final application.
The die or mold is the most important element in the process. It is typically made from high-grade steel to withstand the high pressures and temperatures involved in die casting. The mold consists of two halves: the cavity (where the molten aluminium will be injected) and the ejector (which pushes the finished part out).
Before casting, the die is lubricated to ensure smooth release of the part once it has solidified. Preheating the die is essential to prevent thermal shock and ensure even cooling of the molten metal.

Aluminium ingots are melted in a furnace and heated to around 700°C (1,292°F). Once the aluminium reaches the desired temperature, it is injected into the mold under high pressure (typically between 1,500 and 25,000 psi). This pressure ensures that the molten aluminium fills all the intricate features of the mold, avoiding defects like porosity or voids.
