Custom Automotive LSR Overmolding Silicone Parts Waterproof Liquid Silicone Rubber OEM Solutions for Connectors Sensors and Auto Electronics

In modern automotive engineering, components are required to perform reliably under extreme temperatures, moisture exposure, vibration, and chemical environments. Traditional materials often fail to meet these demanding conditions, leading to sealing failures, reduced lifespan, and costly maintenance.

At SiliconePlus, we provide advanced Liquid Silicone Rubber (LSR) overmolding solutions designed specifically for automotive components, delivering superior sealing, durability, and long-term reliability.

Our automotive silicone parts are manufactured using high-performance LSR combined with engineering substrates (plastic or metal) to achieve optimal functionality.

Excellent thermal stability (-40°C to 200°C+), UV resistance, and anti-aging performance. Maintains elasticity even in harsh environments.

Compatible with PA, PBT, PC, metal inserts, and other engineering materials for structural strength and conductivity.

Using precision liquid injection molding (LIM) technology, we achieve seamless encapsulation and strong bonding without adhesives.
