Vacuum Casting

Vacuum casting prototyping is a versatile manufacturing technique used to create high-quality prototypes and small-batch production parts. The process involves producing a master model, typically through CNC machining or 3D printing, and then creating a silicone mold around it. Liquid polyurethane or other casting resins are then poured into the mold under vacuum conditions, eliminating air bubbles and ensuring precise, defect-free parts. The result is a prototype that closely replicates the appearance, texture, and functionality of injection-molded components—but at a fraction of the cost and lead time.

This method is especially suited for design validation, functional testing, and low-volume production, making it a popular choice across industries where speed, quality, and cost-efficiency are essential.
