Gravity Die Casting Manufacturers

What is aluminium gravity Die casting ?

Aluminium Gravity casting is a permanent mold die castings process, normally someone also call it low pressure die casting; it is one type of metal die casting process. furthermore A process for casting a molten metal into a mold to obtain a casting products. Since a metal type mold can be poured hundreds to thousands of times,Therefore, metal casting mold need to be reusable; that’s point difference with sand casting.

Metal casting is suitable for large batches production of non-ferrous alloy castings; such as aluminum alloys and magnesium alloys with complex shapes, and also suitable for the production of castings, ingots, etc. for steel and with metal insert.

The molten Aluminium alloy material is usually poured into the die by hand, relying on the weight of the molten metal. Filled with cavity, Venting, Cooling, Mold opening to get products, You can find the Aluminium gravity die casting process step by step
