Die Cast Gear.JPG

Using our in-house tooling department, we cut a hard tool from steel.

Molten metal is injected into the cavity under high pressure filling thin walls and small features. The metal solidfies very quickly and the die is opened to eject the casting(s). The tooling can be single or multicavity depending on part size and quantity requirements. Expected tool life can vary based on the tooling material and part geometry.

Die casting eliminates the cost of labor and materials for single use molds and is the most economical method for making high quantities of parts in a short time. American made die castings can are often cost competitive with foreign made parts, with superior lead times, quality, and shipping costs. Tooling for die casting is designed to last for thousands of shots without degradation.

Die casting is often a natural progression for RPM parts to move from prototyping and small volumes, to production and higher volumes. Our die casting service is offered through a strategic partnership with a local partner foundry. 

Advantages: Most consistent geometry; durable tooling can produce thousands of parts; can rapidly produce hundreds or thousands of castings; excellent option for production parts. 





I had success with Prototype Casting several years ago when I previously worked at a defense contractor.   Recently, when I needed a large casting for a new medical device, Prototype Casting again delivered  top quality parts.   Their team was knowledgeable, easy to work with and extremely responsive to my quality and schedule needs.    I want to thank Karl and the team for helping me to succeed with my project.
