Aluminum Gravity Castings

Gravity casting is a casting process used for non-ferrous alloy parts. Also, we called Permanent Mould, the process is typically used on aluminum and zinc.

Advantages

There are many advantages to gravity castings. It offers good dimensional accuracy, a smoother cast surface finish than sand casting, and improved mechanical properties compared to sand casting. Gravity castings also provide faster production times compared to the other processes. Besides, the mold/tooling cost is much cheaper than Die Casting, it is approximate only 30% cost compare to die casting tooling.

Our company has ourselves engineers team to design gravity casting tooling and have an internal tooling workshop to machining the tooling/mold, which will greatly help clients to improve the casting quality, shorten the 1st article sample approval time and save the tooling cost.

Benefits

Gravity casting

  • is cost effective
  • produces good quality components
  • offers process control
  • is best for creating small scale parts
  • does not require a large machine to inject the metal
  • needs much less start up cost than die casting
  • lends itself to more material types

Alloys and Size Range

For small volume orders and designs with undercut, we can provide gravity castings made of aluminum alloys such as A356, A360, A413.2, or others (e.g., copper).

The maximum size of gravity castings we can provide is 1,200 mm x 1,200 mm, the maximum weight is 30 kg.
