Our Metal Casting Processes

Offering Rapid Prototype, Low-Volume Rubber Plaster Mold, or Sand Castings in as quickly as 5 days.

We strive to produce a perfect pour every time. Saving our customers time and money.

Rubber Plaster Mold vs Investment casting

Rubber Plaster Mold Castings

Our most popular casting method.  RPM castings use a rubber mold as the “die.” This type of casting is an exceptional alternative to permanent mold, investment, or die-casting providing almost identical results with a huge cost-saving advantage.

Match plate sand casting

Sand Castings

This is a great alternative to die casts and permanent mold castings. We can accomplish smooth surface finishes of Ra 120-220 similar to die cast results without heavy upfront cost.

Quality Metal Castings and Machining 

Part geometry, quantities requirements, and turn-around are factors that determine the optimal process to be used to produce your part.

Our capabilities range from simple to complex part designs that are beyond the technical capability of most other prototype and low-volume production suppliers.

We metal cast and machine “real” prototypes, and because of the quality of our metal castings, most customers use our prototypes as their low-volume production parts.

Industries We Serve
