From silicone compounds to finish parts
We transform high-performance silicone compounds into precision-engineered parts through advanced manufacturing processes of Compression Molding, Overmolding or LSR Injection Molding. Our complete production workflow ensures superior quality from material selection to final inspection.
Material Preparation Stage
Raw silicone compound inspection (viscosity, hardness verification) Vacuum degassing (30-60 minutes at 0.5-1.0 bar) Precision color mixing (Pantone matching ±0.5ΔE)
Injection/Compression Molding
LSR Injection: Low-pressure injection (15-100 bar) Cure time 15-90 seconds (depends on wall thickness) HCR Compression: Pressure range 50-150 bar Cure time 2-10 minutes
Post-Curing Process
Tunnel oven treatment (200°C × 4 hours) Accelerated aging testing (optional)
Secondary Processing
trimming (±0.1mm accuracy) Plasma surface activation (40-60 W/min) Adhesive bonding (medical-grade adhesives)
Quality Control
100% dimensional inspection Mechanical testing (Shore hardness, tensile strength) Cleanliness validation
Packaging
Anti-static packaging (ESD-safe options) Sterile barrier systems (for medical devices) Barcode tracking system
