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 influence 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.

Compared to sand castings, gravity die casting permits the production of more uniform castings, with closer dimensional tolerances, superior surface finish, and improved mechanical properties.

Metals that can be cast in gravity die casting include Aluminium, Magnesium, Zinc and copper alloys, and hypereutectic Gray Iron.

Dr. Dinesh & Ramesh Engineers (DRE) are experts at producing pressure tight, leak proof, intricate shaped large gravity die castings. We are able to achieve parts from 0.5 kg to 100 kg in gravity die casting.
