Able to cast parts with high mechanical properties and good surface finishes, this process is also known for its good dimensional repeatability and a reduced need for machining, effectively lowering production costs.

Part sizes that can be casted using permanent mold or gravity die casting range from 50 grams (0.5 ounces) to 70 kilograms (150 pounds).

The tolerances for permanent mold or gravity die casted parts are noted as follows:
