Product Description
Anti-Yellowing, UV Resistance LSR Overmolding Custom Silicone Lens Manufacturer in China
The silicone lens is made of high quality, ultran transparent and flame resistance optical silicone materials, processed by ARBURG LSR injection molding machines in Class 100,000 clean production workshop. With 94% light transmittance, the optical silicone rubber has great fluidity and low viscocity, which can help to achieve complex designs. As a product designer, you may want to do a lightweight design, overmolding will be a very helpful technics, not only can lower the product weight, but also reduce the assembly processes.

Overmolding Silicone Lens Optical Performance
The light transmittance for most optical silicone lenses are over 94%. The overmolding silicone lens has super excellent weatherability, under harsh conditions, the color keeps stable and the product is without any deform. It's UV resistance, anti-yellowing and flame resistance, after 3000 hours 85℃/ 85% aging testing, the silicone lens is no changing. Temperature resistance can be from -40 to 150 Celsius degrees. Becuase of these characteristics, the optical silicone lens is getting popular.

FAQ
Q: Why you should choose our factory to be your partner for LSR injection molding silicone lens? A: With a professional optics doctors and masters to offer technical support, from the very beginning to evaluate the feasibility of your design to mass production. Also, our factory has many advanced and imported mold making equipment, silicone injection molding and performance inspection equipment. |
Q: What's optical silicone? A: Optical silicone is a bi-component ultra-transparent liquid silicone rubber material, with very good optical properties and flame resistance. Under long-term harsh environment, for example, under high temperature or UV radiation, the color keeps stable and the optical clarity maintains. In addition, the excellent processing properties enable it to be manufactured to tight tolerance complex or micro-structure optical parts, which brings new possibilities for cutting-edge technology in LED high-powered automotive lighting and electronics. |
Q: What's the advantage to choose optical silicone to make silicone lens? A: Comparing to Plastic, the properties of light transmittance, anti-yellowing and weathering resistance are better. Comparing to Glass, the optical liquid silicone is easy to shape, the fluidity makes the complex or micro-structure designs moldable. |
Q: Can you design silicone lens? A: For now, we just do OEM designs. Our team is unable to do the product design. |
Q: What should I offer to custom silicone lens? A: Please offer us 3D drawing and performance requests. |
Q: Can I visit your factory? A: Yes, should any interest, highly welcome to visit our factory. |
