Custom OEM LSR Overmolded Plastic Components Waterproof Dustproof Corrosion-Resistant Silicone Parts with Soft-Touch Finish

Our custom OEM liquid silicone rubber (LSR) overmolded plastic components are engineered to deliver superior durability, sealing performance, and tactile comfort. Designed for demanding industrial and medical applications, these silicone overmolding solutions combine rigid plastic substrates with soft, high-performance silicone to create reliable, long-lasting components.

In many industries, traditional plastic parts face critical challenges such as poor sealing, discomfort during use, vulnerability to environmental exposure, and limited durability. Our LSR overmolding technology effectively solves these issues by integrating soft-touch silicone with strong structural materials.

Poor sealing → Upgraded waterproof and dustproof protection

Hard surfaces → Enhanced ergonomic soft-touch feel

Environmental damage → Excellent resistance to chemicals and corrosion

Short lifespan → Improved durability and mechanical performance

We use premium-grade liquid silicone rubber, known for its outstanding properties:

Excellent biocompatibility (optional medical-grade)

High resistance to temperature, UV, and chemicals

Long-term elasticity without deformation

Non-toxic, odorless, and environmentally safe

Our precision LSR overmolding process ensures seamless bonding between silicone and plastic substrates such as PC, ABS, or nylon. With advanced injection molding and multi-shot technology, we achieve:
