Gravity die casting equipment has a vertical or horizontal mould opening, or tilting technology with 0/90 ° or 0/120 ° tilting provides an alternative. With tilting die-casting, the metal flow at the die inlet is controlled by the tilting angle and speed of the die.

The goal is to fill the die with minimum turbulence through one or more channels to reduce oxidation and foaming. This minimises porosity and inclusions, giving optimum metal characteristics in the final casting.

Gravity die casting was one of the very earliest processes to be invented for metal and light alloy die casting. In this process which can be fully automated, the molten metal is poured directly from a ladle into a semi-permanent or permanent die.

One of the advantages of tilting gravity die casting is that it can produce dense, high quality castings with excellent mechanical attributes like strength and stiffness.
