OEM Silicone Vacuum Casting Service with ±0.01mm Tolerance and 50-100 Parts per Mold for Automotive and Medical Applications

Our advanced 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 model in a specialized frame, placed in a vacuum environment to eliminate bubbles, then heat-cured to form durable silicone molds. Precisely proportioned liquid plastic materials like polyurethane resin are injected into the mold under vacuum conditions to ensure uniform distribution and bubble-free results, followed by heat curing and final finishing processes.

• Cost Efficiency: Silicone molds can be reused 50-100 times, significantly reducing production costs compared to traditional injection molding
• High Precision: Exceptional dimensional accuracy with tolerances of ±0.01mm to ±0.1mm
• Rapid Production: Fast turnaround from model creation to finished parts for quick product iteration
• Material Flexibility: Compatible with ABS, PP, PC, POM, PMMA, NYLON, TPE, TPU and other materials
• Surface Quality: Superior finish options including polishing, texture, glossy finish, painting, and silk printing

• High detail restoration with excellent surface finish and stable dimensional accuracy
• Low mold cost with simple manufacturing processes and material savings
• Short production cycle without complex mold opening procedures
• Material flexibility with various polyurethane resins and epoxy resins
• Vacuum environment molding for bubble-free, dense parts with enhanced mechanical properties
• Wide application range including automotive accessories, medical devices, electronic housings, and consumer products

Silicone vacuum casting parts serve multiple industries including automotive (interior components), medical devices (high-precision instrument accessories), consumer electronics (enclosures with excellent texture), aerospace, marine, sporting goods, cultural arts, jewelry design, and scientific research equipment. This process enables rapid prototyping, small-batch production, and customized parts manufacturing across various sectors.

Parts are protected with anti-static pearl cotton or bubble film, placed in customized hard paper boxes with shape-fitting grooves, and secured in high-strength five-layer corrugated outer boxes with protective corner guards and appropriate labeling.

We verify order details before shipping and select appropriate logistics methods (international express, air, or sea). Customers receive tracking information and we monitor shipments to ensure timely delivery with proper customs clearance handling.
