Vacuum Casting (Silicone Mold)
Professional Silicone Mold Vacuum Casting Service | Low-Volume Rapid Production
What is Vacuum Casting?
Vacuum Casting (Silicone Mold Casting) is a high-efficiency rapid manufacturing technology for small-batch production. It uses 3D printed master parts to make flexible silicone molds, then casts polyurethane (PU) parts under vacuum environment.
This technology is perfectly suitable for 10 - 500 pieces production, with performance close to injection molding, but with lower mold cost and shorter lead time, widely used for product prototyping and small-batch manufacturing.
Key Advantages
Low Cost
90% lower cost than steel mold, ideal for small-batch production without expensive investment.
Fast Lead Time
7-15 days rapid delivery, mold making + casting completed in short time, speed up your project.
High Precision
Smooth surface, clear details, tolerance up to ±0.1mm, same as injection molded parts.
