Meet Rilong Precision Mold at Embedded World 2026, Stand 3A-366.
The automotive industry is undergoing rapid innovation, driven by the need for lighter, safer, and more durable materials. Among these, Liquid Silicone Rubber (LSR) has emerged as a game-changing material, offering unparalleled properties that meet the rigorous demands of modern vehicles. In this blog, we’ll delve into the diverse applications of LSR in the automotive sector, complemented by exclusive production and product photos showcasing LSR over-molding technology.
Why LSR? Key Advantages
LSR is a versatile material with exceptional properties that make it ideal for automotive applications:
- Thermal Stability: LSR maintains its performance under extreme temperature ranges (-50°C to 200°C), making it perfect for components exposed to engine heat or cold climates.
- Durability: It offers excellent resistance to UV, ozone, and weathering, ensuring long-lasting performance.
- Flexibility and Elasticity: Its superior elasticity allows for precise sealing and vibration absorption.
- Biocompatibility and Safety: LSR is odorless, non-toxic, and complies with stringent automotive standards.
- Precision Manufacturing: Its compatibility with advanced molding techniques like over-molding and multi-shot molding enables the production of complex components with high accuracy.
Applications of LSR in the Automotive Sector
1. Seals and Gaskets
Seals and gaskets are crucial for maintaining the efficiency and safety of automotive systems. LSR’s resistance to extreme temperatures and chemicals ensures reliable sealing in:
- Engine components
- Lighting assemblies
- Battery enclosures for electric vehicles
2. Vibration and Noise-dampening
To enhance ride comfort, LSR is used in anti-vibration components. Its elasticity reduces noise and vibration effectively, improving the overall driving experience.
3. Interior Touchpoints
LSR’s soft touch and durability make it an excellent choice for buttons, knobs, and touchpads in vehicle interiors. These components not only provide tactile satisfaction but also withstand repeated use.
4. Optical Applications
High-transparency LSR is widely used in lenses for automotive lighting and sensors, such as ADAS (Advanced Driver Assistance Systems). Its optical clarity ensures reliable performance in critical safety systems.
5. Overmolded Parts
LSR’s compatibility with other materials enables over-molding applications, where LSR is molded over plastic or metal substrates to create hybrid components. This technique is often used in:
- Connectors
- Handles
- Protective covers
Behind the Scenes: LSR Overmolding Process
Our manufacturing facility employs state-of-the-art LSR over-molding technology to produce high-quality automotive components. Here’s an overview of the process:
