Description
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.
