Revolutionary Multi-Material LSR Molding Technology
We integrate Liquid Silicone Rubber (LSR) with plastic, metal, PP and even three-material hybrid structures in a single shot. Our new process unlocks next-generation product designs with higher sealing, durability and design freedom.
What Makes Multi-Material LSR Molding So Powerful?
Multi-material LSR molding combines Liquid Silicone Rubber with one or more substrates—such as PC, PP, nylon, stainless steel, aluminum or electronic inserts—into a single integrated part. Instead of separate components and glue, our new process achieves direct bonding during injection.
This advanced process delivers:
- Zero-gap sealing and high waterproof performance
- Excellent chemical and temperature resistance
- Thin-wall and complex 3D geometries
- Integrated soft + hard structures in one part
- Stable and repeatable quality for mass production
We Support All Key Multi-Material LSR Combinations
From simple LSR + plastic overmolding to complex three-material integrations with metal and PP, our new process helps you build stronger, safer and more compact products.

Why Multi-Material LSR Outperforms Traditional Assembly
Compared with traditional glue bonding and screw assembly, our multi-material LSR process delivers a higher-performance, cleaner and more reliable solution.
1. 100% Leakage-Proof Structure
Direct bonding during injection molding ensures ultra-tight sealing performance, significantly reducing the risk of leakage and failure.
2. Ultra-High Durability
Excellent resistance to chemicals, cleaning agents, high and low temperatures, UV and repeated sterilization cycles.
3. Complex Structures, Zero Assembly
Soft and hard parts are formed together in one piece, reducing components, labor, assembly time and long-term maintenance costs.
4. Perfect for Mass Production
Automation-friendly process ensures consistent quality, short cycle times and stable performance for large-volume orders.
