Let’s make your CAST URETHANE parts. Right now.
Reduced cast urethane costs by 60%
Made possible with Fast radius
Every day we’re working with the world’s leading product manufacturers to make the parts that matter most to their businesses.
Common Cast Urethane Applications
Cast urethane is often used in low to medium volume part production. It can also be a smart option for prototyping components, as a new tool can be cured quickly for each design iteration.
Joints
Ideal for producing mechanical joints with overlapping features.
Logos
3D logos with raised or recessed lettering.
Prototyping
Low up-front cost and quick turnaround times.
Low volume production runs
Producing plastic components needed in small quantities.
