Aluminum die casting is a highly efficient manufacturing process widely used to produce complex, high-precision metal parts with excellent surface finish and dimensional accuracy. Predominantly employing high-pressure techniques, it has become indispensable in industries requiring lightweight yet strong components, such as automotive, aerospace, electronics, and consumer goods.
Overview of the Process
Aluminum die casting involves forcing molten aluminum alloy into a reusable steel mold (called a die) under high pressure. This method allows for rapid production of intricate shapes that would be difficult or costly to achieve with other manufacturing techniques.
The most common variant is high-pressure die casting (HPDC), which uses pressures ranging from 1,000 to over 20,000 psi. For aluminum, the cold-chamber process is standard because aluminum's higher melting point (around 660°C or 1,220°F)
