Product Description
Custom Silicone Vacuum Casting Process
Crida silicone vacuum casting plastic parts utilize silicone molds and vacuum environments to manufacture high-quality plastic components. This advanced process is ideal for small batch production and rapid prototyping applications across various industries.
Manufacturing Process
The process begins with creating high-precision prototypes using 3D printing or CNC machining. These prototypes are then placed in specialized frames where liquid silicone is injected after vacuum degassing. Once solidified, the silicone mold accurately replicates even the most intricate details of the original prototype.
Two-component polyurethane (PU) resin is precisely mixed and vacuum degassed before injection into the silicone mold under vacuum conditions. This ensures complete filling, eliminates bubbles and shrinkage marks, and guarantees dimensional accuracy. After curing, parts undergo post-processing including trimming and polishing to achieve final specifications.
Key Features & Advantages
- Cost-Effective: Low-cost silicone molds reduce initial investment compared to traditional injection molding
- Rapid Production: Complete process from prototype to finished product typically takes only a few days
- Material Versatility: Polyurethane resin can simulate various plastic properties including PC transparency and PP fluidity
- High Precision: Tolerances controlled within ±0.05mm for accurate dimensional reproduction
- Superior Surface Quality: Vacuum casting eliminates bubbles for smooth, polished surfaces
- Design Flexibility: Easy design modifications through prototype adjustments without expensive mold changes

Application Areas
Low-Volume Production
Ideal for production quantities that don't justify injection mold tooling investment. Perfect for first-run production parts that can be completed weeks before production tooling readiness.
Advanced Prototyping
Cost-effective design modifications with relatively inexpensive tooling. Same molds can utilize different materials for comprehensive design testing.
Market Testing
High-quality finish and end-user functionality make urethane cast parts perfect for consumer testing, user evaluation, and concept model development.
Packaging & Shipping
Secure Packaging
Parts are carefully wrapped with bubble film and pearl cotton for protection. High-precision components receive custom EVA lining or foam molds to prevent movement during transit. Moisture-sensitive items are sealed with desiccant for international shipping protection.
Global Logistics
Multiple shipping options including DHL, FedEx for express delivery, and sea/air freight for larger quantities. Complete customs documentation provided for smooth international clearance.
