DIE CASTING

Quality DIE CASTING Service

Aluminum die casting is a manufacturing process where molten aluminum (or aluminum alloys) is forced under high pressure into a steel mold or die to produce complex, precise, and durable components. This method is widely used in various industries, including automotive, aerospace, electronics, and consumer goods, because of its efficiency and the excellent material properties of aluminum.

Process of Aluminum Die Casting

Die Preparation:

  • The steel mold is cleaned, lubricated, and pre-heated.

Injection:

  • Molten aluminum is injected into the mold cavity under high pressure.

Cooling:

  • The aluminum solidifies quickly within the die.

Ejection:

  • The part is ejected from the mold.

Trimming:

Excess material (like gates or runners) is removed from the cast part.

True. The final metal parts are plane, defined, and textured-surfaced. Aluminum has such properties perfect for casting as corrosion resistance, lightweight and strong and good thermal conductivity.
You can produce a variety of attractive shapes with accuracy.

Not ideal for low-volume production due to high initial tooling costs.Limited to parts that are relatively thin-walled.May develop porosity, which can weaken the part in some cases.
