Molten metal is forced into a mold in Die casting or aluminum die casting, which is a metal casting process. Dimensionally accurate precision metal parts are produced by it that have a flawlessly smooth finish. Its ability to produce detailed parts makes it a perfect choice for mass production products. From non-ferrous metals such as magnesium, copper, aluminum, zinc, lead, pewter, and tin die castings are made.

In die casting, the two methods are hot or cold chamber. On the type of metal and the part the process that is used generally relies on. In metals that have a high melting point such as alloys of aluminum, brass, or copper the method of the cold chamber is used. Metals that won’t dissolve when heated such as zinc, lead, and magnesium alloys, the method of hot chambered die casting is used.

The process of die casting is quite efficient, economical and it offers a broad range of shapes and components. Parts that are produced have a long life and are visually appealing giving designers significant benefits.

Complex shapes with close tolerances that need no after production processing are produced at the high speed of die casting. There is no requirement for additional tooling or shaping. The final Lighting die casting part that is produced is heat resistant with high tensile strength.

Different Metals Used in Die Casting

In die-cast, the type of metal needed depends on its final use. Because of its lightweight and corrosion resistance, Aluminum is used for automobile and truck parts. During and after the melting process metals for casting must be able to maintain their properties and characteristics. The types are:

• Zinc

• Lead

• Brass

• Aluminum

• Stainless steel

• Tin

• Magnesium

• Carbon steel

• Bronze


In metal casting, zinc is the easiest metal to cast. It can easily be plated, has high ductility and impact strength. The low casting temperature of zinc usually results in minimal thermal shock, which helps in extending the life of die casting tools more than 10 times when compared to aluminum dies.

Due to zinc's bearing properties bushing and wear inserts in component designs can be eliminated, and in heavy-duty industrial applications, it outperforms bronze. The furniture die casting part is used popularly.
