In-hose curing risk caused by rapid curing
硅胶注塑成型
Silicone injection molding is used to produce seals, gaskets, membranes, keypads, lenses, and encapsulated components that demand high dimensional stability and consistent material performance. Liquid Silicone Rubber (LSR) offers excellent thermal stability, chemical resistance, and elasticity, making it ideal for applications requiring durability and biocompatibility. However, LSR materials are shear-sensitive and fast-curing, demanding precise control over mixing ratio, temperature, pressure, and injection timing. A reliable silicone injection molding system ensures void-free filling, clean cavity separation, and consistent shot volume, enabling defect-free production and long-term component reliability.
Key Challenges in Silicone Injection Molding
Ratio deviation and incomplete mixing
Air entrapment and void formation
Temperature fluctuation and viscosity drift
Our Solutions
NEXGEN’s silicone injection molding system is engineered for accurate, stable, and contamination-free processing of liquid silicone rubber and other two-component elastomers. The system integrates metering pumps and precision mixers to maintain perfect ratio accuracy and smooth flow control. With temperature-regulated feed units and vacuum-assisted degassing, it guarantees bubble-free injection and clean cavity separation. Designed for automated manufacturing, the system ensures:
- Precise ratio metering and homogeneous mixing of LSR materials
- Bubble-free injection and uniform cavity filling
- Clean cutoff with no leakage or drooling between shots
- Reduced material waste and improved process sustainability
