What is Vacuum Casting?

Vacuum casting or urethane casting is a low-volume manufacturing process where silicone molds replicate master models to produce precise polyurethane or resin parts under vacuum, ensuring minimal air bubbles and high fidelity.

Cost-effective for prototypes and small production runs
High surface detail and smooth finishes
Multiple material options including flexible, rigid, and transparent
Rapid turnaround, ideal for design validation
