UV Resistance Anti-yellowing Silicon Optics Made by LSR Injection Molding

Product Information

Applications of Anti-UV Silicon Optics

Anti-UV silicone optics are primarily used for outdoor and specially designed LED lights due to their anti-yellowing and heat resistance properties. This silicone material can withstand prolonged exposure to UV light without changing color. Additionally, it can endure temperatures ranging from -40 to 150 degrees Celsius. In some specially designed LED lights, using plastic lenses can lead to burning and yellowing over time, while silicone optics remain unaffected.

Features of Optical Liquid Silicone

Optical silicone is a high-performance liquid silicone rubber material with the following features:

• High Light Transmittance: Provides excellent clarity and allows maximum light passage.

• Temperature Resistance: Maintains performance across a wide temperature range, ensuring durability in various environments.

• UV Resistance: Effectively withstands ultraviolet light exposure without degrading or yellowing.

• Low Density: Lightweight, making it suitable for applications where weight is a concern.

• Low Refractive Index: Minimizes distortion and enhances optical clarity.

• Anti-Shock: Offers superior shock absorption, protecting sensitive components.

• Flame Resistance: Resists ignition and minimizes flame spread, enhancing safety.

• High Flexibility: Can be overmolded with other materials, allowing for the creation of sharp angles, undercuts, and intricate micro-structures.

  
  

Why Choose YEJIA to Customize UV Resistance Silicon Optics?

Manufacturing silicone optics requires manufacturers to possess skilled mold design and mold-making experience, particularly due to the tight tolerances and optical surface finish requirements. For LSR molding, not only must the production environment be clean, but the LSR molding machines also need to be of high precision. YEJIA has imported world-class mold-making equipment and many experienced experts from Japan, Korea, and China. Additionally, we have Class 100,000 clean production workshop for LSR molding and imported Arburg LSR molding machines. With top-notch technical and production capabilities, YEJIA has established itself as a leading manufacturer of silicone optics in China.

Production Process of LED Lighting UV Resistance Silicon Optics

The production process for silicone optics begins with tooling design. When customers provide YEJIA with 3D and 2D product drawings, we evaluate the feasibility of production and discuss mold design with them. Once the Design for Manufacturing (DFM) report is confirmed, we proceed with mold manufacturing. After the mold is finalized, we initiate LSR injection molding for mass production, which includes gate removal and post-curing processes. In addition to the thorough inspections conducted at YEJIA, customers will perform functional tests alongside us. As a partner, YEJIA is committed to supplying the highest quality products to help our customers establish a strong reputation in the market.
