In this process, a metal moulddie is mounted on above a sealed furnace containing molten aluminium metal. A riser tube connects the bottom of the die to the molten metal bath. the sealed furnace containing the molten metal is pressurised (typically 3-35 psi), and the metal is forced up into the moulddie slowly at a steady predeternmined rate. It is important to determine the rate of filling to avoid entrapment of air and turbulence giving homogenous defect free parts. The pressure is usually given to feed the defects like shrinkage normally associated with casting process.

Gravity Die Casting is a process in which molten metal is poured in a metal mould (usually of iron) under the working of gravity. Since the metal enters the mould under the infulence of gravity the process is called as Gravity Die Casting (GDC). Permanent mold is another name for Gravity Die Casting primarily used in USA and Canada.
