Liquid Silicone Rubber Custom Component Solutions
What is LSR Molding?
Liquid Silicone Rubber (LSR) injection molding is a process where liquid A & B components are precisely mixed, injected into a mold, and thermally cured to create high-performance silicone parts. Unlike traditional rubber, LSR offers:
✔ Ultra-low shrinkage (∼0.1%)
✔ Exceptional durability (heat, chemical & UV resistant)
✔ Medical & food-grade safety (FDA, LFGB compliant)
LSR Double Injection: The Next-Level Advantage
Combine LSR with thermoplastics or other materials via two-shot molding for:
✔ Seamless bonding – No adhesives needed, just ultra-strong, leak-proof assemblies
✔ Multi-material flexibility – Soft-touch grips + rigid structures in a single cycle
✔ Cost-efficient production – Reduced assembly steps, higher consistency

LSR Molding Technology
🔹 Standard LSR Injection – Seals, gaskets, soft-touch components
🔹 Special LSR Formulations – High-temp, electrically conductive, or optically clear silicones
🔹 Overmolding:
- LSR + Plastic – Enhanced grip & sealing (e.g., toothbrush handles)
- LSR + Metal – Vibration-damping, airtight assemblies (e.g., sensor housings)
- LSR + Glass – Medical & optical applications (e.g., lenses, lab equipment)
- LSR + Electronics – Waterproofing & shock absorption (e.g., wearables, connectors)
