Gravity die casting is one of the first metal and light alloy die casting processes invented. In this process, which can be fully automated, molten metal is poured directly from a ladle into semi-permanent or permanent molds.
The goal is to fill the mold with minimal turbulence through one or more channels to reduce oxidation and foaming. This minimizes porosity and inclusions, providing optimum metallic properties in the final casting.
Gravity casting equipment can have a vertical or horizontal mold opening, or tilting technology with a 0/90° or 0/120° tilt offers an option. In tilt die casting, the metal flow at the die entrance is controlled by the tilt angle and speed of the die.
