What is Urethane Casting?
Urethane casting, also known as vacuum casting, is a manufacturing process used to create high-quality plastic parts by pouring liquid polyurethane resin into a silicone mold under vacuum pressure. The vacuum removes air bubbles and ensures smooth surfaces, accurate details, and strong mechanical properties.
This process is widely used for functional prototypes, product validation, and low-volume production runs. A master model typically produced by CNC machining or 3D printing—is used to create the silicone mold, allowing fast tooling and cost-efficient manufacturing compared to injection molding.
At XY Machining, our engineers carefully manage mold design, resin selection, and curing cycles to deliver repeatable, production-quality polyurethane parts.
