Make your project possible

Harness cutting edge technology to take your project from prototype to production

Manufacture a spectrum of cast urethane parts with high levels of geometric complexity and detail and without costly tooling requirements. During the urethane casting process, resin is poured into a silicone mold which is then left to cure in a vacuum chamber to form a solid part. The speed of urethane casting tooling production makes the process ideal for low to medium volume production runs and for the rapid manufacture of prototype parts.

Get your urethane casting project started today. Upload your CAD file to our Cloud Manufacturing Platform™ to receive a quote, work with our engineers to optimize your design, and move to production when you’re ready. You can specify the post-processing and finishing options you need for your parts, along with any inspection requirements. When your order is ready, we’ll package and ship the finished parts to you.

Urethane casting applications

Urethane parts are used in an array of industrial applications, including:

Consumer testing

Cast urethane prototypes are used widely for consumer testing purposes, enabling manufacturers to explore varieties of size, strength, material, and color quickly and cost-effectively.

Bridge tooling

The flexibility of the urethane casting process makes it ideal for bridge tooling, enabling parts production at a lower volume while production tooling scales up.

Joints casting

Urethane casting is ideal for manufacturing strong, durable mechanical joints with overlapping features.


The precision and consistency of urethane casting makes it particularly effective in the production of 3D logos and letters.
