This process is almost universally selected for high-pressure die-casting components in zinc alloys. Metal is melted in a crucible with a hollow protrusion on one side, (generally called a gooseneck), located into the entrance to the die. A force pump mechanism, which has one end submerged in the molten metal, injects the molten metal into the die. A runner system allows the metal to enter the component cavity or cavities through one or more ingates. Overflow runners may be provided to improve integrity and surface finish as appropriate.
