A form of die casting is Gravity die casting from an aluminum die casting tooling manufacturer. For creating high-volume parts and repeatable medium, it is perfect. Permanent mold is often involved in this process. From high-pressure die casting, it is different. For parts that have higher structural requirements are slightly larger, and heavier, it is used rather than high pressure die casting.

Molten metal as with other forms of die casting is formed into a shape with the help of a mold cavity. To produce the same part, this method allows a single set of dies to be indefinitely reused. As the cost of casting machinery and the metal dies can be high, this is fortunate. Because of their excellent strength and surface finish, Gravity die castings are desirable.
