What They're Saying
“ProtoCAM's turnaround times are exceptional, and their prices compared to others are always better. There's a lot more value added in working with ProtoCAM.” — Matthew Bellenoit, B. Braun Medical
“There are many companies in the rapid prototyping business that are automated and there’s no personal interface. That's the big difference between ProtoCAM and other companies.” — Jim Eldon, Design Associates
“When we need to make a change, ProtoCAM always accomplishes it accurately. We see the results we planned on consistently. They do a very good job providing quality products.” — Rory Kiphart, Biomet
“I’ve worked with a lot of different rapid prototype houses and I've consistently ended up back at ProtoCAM. Quality is key and they deliver consistently. They’ve given us a significant advantage over our competitors.” — Dan Dunham, XOS
“ProtoCAM's best attribute is their attention to detail and customer service. Their willigness and desire to keep in touch with me is impressive, and physical walkthroughs ensure me quality standards are being met.” — Todd Frick, Clair Brothers Audio Systems
In urethane casting a liquid material is poured into a mold containing a hollow cavity in the shape of the part, then allowed to solidify. The technique allows for the creation of small quantities of production-ready parts without the added expense of machine tooling.

About Urethane Castings
Urethane casting (or polyurethane casting) is ideal to rapid prototype short-run production of pieces made from a plastic injection molded resin. Often performed after an RTV mold (also called a room temperature vulcanization mold) is made from a stereolithography (SLA) prototype, urethane casting is a cost-effective way to reproduce production-ready parts in small quantities.
After a mold is created, urethane casting material – synonymous with polyurethane casting material – is injected into the mold’s “void.” This allows for near-perfect copies of the original prototype to be created. We have low durometer urethanes that can be very soft, but we can also make stereolithography molds and inject silicone rubber into it.

Urethane casting provides:
- Accuracy: A high degree of accuracy is maintained in the copy – including surface finish.
- Versatility: Parts without draft, or with undercuts, can be reproduced. Likewise, different materials can be used with the same mold, making it possible to test designs with a variety of material properties.
- Speed: Several parts can be created per shift once the mold is complete.
