In the fast-evolving landscape of smart devices, traditional optical materials like glass and plastic are increasingly falling behind. Glass lenses are heavy and fragile, while plastic optics often warp or degrade under high temperatures. To meet the demands of next-generation applications, YEJIA introduces a transformative solution: LSR overmolded optical silicone lens technology — a game-changer in modern optical manufacturing.

YEJIA’s breakthrough integrates liquid silicone rubber (LSR) seamlessly with plastics and metals, creating high-performance, durable optical components. Already deployed in cutting-edge applications such as ADB high/low beam automotive headlights, this innovation is setting a new benchmark across industries including automotive, consumer electronics, and medical devices.

Silicone Optics: The Future of High-Performance Light Control

Silicone optics are rapidly becoming the material of choice for demanding optical applications. Thanks to its unique molecular structure, optical silicone delivers:

✓ Exceptional Light Transmission

With over 94% transmittance, optical silicone lenses rival the clarity of glass while outperforming conventional plastic lenses that only achieve 85–90%.

✓ Extreme Temperature& Environmental Resistance

From -40°C to 150°C, YEJIA's silicone lenses maintain their shape and optical integrity — solving fogging, yellowing, and deformation issues in automotive and outdoor environments.

✓ Radical Manufacturing Efficiency

By leveraging LSR injection molding, production cycles for complex light guide silicone matrix components can be reduced by up to 70%, with manufacturing costs slashed by up to 50%.

YEJIA’s advanced LSR overmolding technique transforms silicone into a resilient yet precise optical solution — ideal for applications where flexibility, clarity, and durability are essential.

Automotive Optics Reinvented: Durable, Smart, and Reliable

Traditional modular headlight systems are prone to failure under thermal stress and vibration. YEJIA’s silicone optics overmolded with engineered plastics provide seamless encapsulation, eliminating gaps and weak points.

Proven Performance:

1. 78% reduction in headlight failure rates (validated by leading Chinese EV manufacturers)
2. Withstands temperatures up to 150°C
3. Fully compliant with IP69K for high-pressure wash durability

YEJIA's optical silicone lens technology ensures that smart lighting systems remain reliable, even in the harshest road conditions.
