What is Vacuum Casting
Vacuum casting is a rapid prototyping and small-batch production process for plastic and resin parts. Using a silicone mold derived from a master model, liquid polyurethane or other engineering resins are poured under vacuum to create high-detail, precise, and functional parts. This process ensures minimal air bubbles, smooth surfaces, and excellent dimensional accuracy
When to Use Vacuum Casting
Vacuum casting is ideal when you need:
- Functional prototypes for testing form, fit, and function
- Low-volume production of parts (typically 10–1000 units)
- Quick turnaround without investing in expensive metal tooling
- High-detail parts that replicate the look and feel of final products
