Choosing Between Permanent Mold and Die Casting

Posted by Hill and Griffith Company on Jan 22, 2020 8:00:00 AM

The metal molds used in die casting and permanent mold casting help drive cost, material choice and casting soundness, but each process offers unique advantages.

Excerpt from the November 2014 issue of Casting Source

The permanent mold and die casting processes share a common ground. While the molds used in sand molding, investment casting and lost foam casting are expendable, metal die casting and permanent molds are used repeatedly. The material and manufacture of the metal molds make initial tooling costs more expensive than the other processes, but if the volume of production is high enough, this cost difference can be overcome. Permanent mold and some types of die casting also offer superior mechanical properties because the metal mold acts as a chill.

Despite the similarities, each process may better suit a particular application, depending on the property requirements, casting size, production rate and design complexity.
