Custom Precision Silicone Vacuum Casting Parts for Medical Devices with ±0.05mm Tolerance and 40°C Curing

Crida silicone vacuum casting is an advanced manufacturing process ideal for small batch production and prototyping. The process begins with creating a master mold from 3D design data using CNC machining or 3D printing technologies like SLA and SLS. For complex structural components, 3D printing ensures precise detail reproduction.

Silicone molds are then created by evenly pouring silicone around the master mold, removing air with vacuum equipment, and curing in a 40°C oven for 8-16 hours depending on mold size. The vacuum casting process involves injecting resin into the vacuum cavity mold under computer control, followed by secondary curing. Small parts cure in 1-3 hours while larger components require 3-6 hours before demolding.

• Cost Efficiency: Requires only one silicone mold versus multiple metal molds for injection molding, significantly reducing tooling costs
• Material Versatility: Uses affordable silicone and polyurethane resins with low energy consumption
• High Precision: Achieves ±0.05mm tolerance with bubble-free vacuum environment production
• Rapid Production: Short design-to-production cycle with mold reusability for quick market response
• Design Flexibility: Accommodates complex shapes, undercut structures, and various sizes
