Briefing
High-precision silicone overmolded metal parts with strong bonding, and durable LSR insert molding for custom OEM projects.
Detailed
Product Overview
Silicone overmolded metal components are produced by bonding stainless steel or alloy inserts with liquid silicone rubber (LSR) through precision injection molding. This hybrid structure delivers high mechanical strength, soft-touch protection, vibration damping, sealing performance, and long-term durability.
At SiliconePlus, we specialize in LSR overmolding and metal insert molding for industrial, medical, electronics, and smart device applications. Our advanced LSR systems ensure strong bonding, tight tolerances, and highly repeatable quality for demanding OEM/ODM projects.
Key Benefits

Surface treatment + high-flow LSR ensures permanent chemical adhesion
No delamination, peeling, or cracking even under long-term stress
2. Precision Injection Molding
Dimensional tolerance up to ±0.02 mm
Suitable for complex geometries, deep grooves, thin-walled parts, and custom inserts
3. Excellent Temperature & Chemical Resistance
Operating temperature: –40°C to 200°C
Resistant to oils, chemicals, aging, oxidation, and environmental stress
4. Safe and Certified Materials
Medical-grade, food-grade, or industrial-grade LSR available
Compliant with ROHS, REACH, FDA, LFGB, UL requirements
5. Wide Application Range
