Custom Silicone Vacuum Casting Plastic Parts with ±0.1mm Tolerance and 7-10 Day Production Cycle

Our silicone vacuum casting process begins with creating a high-precision master model using 3D printing or CNC machining. Liquid silicone is poured around the master in a specialized frame, vacuum-degassed to eliminate bubbles, then heat-cured to form the mold. Precisely proportioned liquid plastic materials (polyurethane resins) are injected into the mold under vacuum conditions to ensure uniform distribution and bubble-free results. After heat curing, parts are removed, deburred, finished, and surface-treated to achieve the final product.

• Short 7-10 day production cycle eliminates complex metal tooling requirements
• Cost-effective for small batches with reusable silicone molds
• High dimensional accuracy with ±0.1mm tolerances and smooth surface finishes
• Wide material compatibility including rubber, TPU, and flexible resins
• Full customization of colors, surface textures, and functional properties
• Vacuum casting ensures minimal bubbles and consistent quality

• Automotive: Interior components, dashboard housings, air vents, exterior prototypes
