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)

01

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

02

Post-Curing Process

Tunnel oven treatment (200°C × 4 hours) Accelerated aging testing (optional)

03

Secondary Processing

trimming (±0.1mm accuracy) Plasma surface activation (40-60 W/min) Adhesive bonding (medical-grade adhesives)

04
Silicone Mould

Quality Control

100% dimensional inspection Mechanical testing (Shore hardness, tensile strength) Cleanliness validation

05
