Product Description

UV Resistance LSR Molding Silicon Optics Factory

Our factory specializes in producing high precision and premium qulaity LSR injection molding and overmolding silicon optics, which are widely used for automotive headlights, indoor and outdoor LED lighting. For over a decade, we've been the top manufacturer of silicon optical lenses. 

LSR Molding Silicon Optics

LSR molding silicon optics is also called LSR molding silicon lens, LSR silicon condensor, made of ultra transparent optical silicone, processed by liquid injection molding. The light guide pins are difficult to process, because each pin has different angle. Yejia silicone has been producing various silicon optics for automotive headlights, as it's an important optical component for ADB (Adaptive Driving Beam) lighting, and we've supplied liquid silicon optics to many famous automotive makers. If you're looking for custom silicon optics, welcome to contact us.

Product Specification

This silicone optics is made of no-yellowing and high light transmission optical silicone, produces in class 100,000 clean production workshop and class 10,000 light performance inspection clean room. With professional engineering team, advanced mold making team, imported ARBURG LSR injection molding machines, our factory aims to be the leader of silicon optics manufacturer.

LSR Molding Silicon Optics


Q: What's the advantage to choose LSR rubber to make silicon optics?

A: Comparing to Plastic, the properties of light transmittance, anti-yellowing and weathering resistance are better. Comparing to Glass, the optical silicone is easy to shape, the fluidity makes the complex or micro-structure designs moldable.

Q: What's the level of your clean production workshop?

A: Currently, for Liquid Injection Molding, the workshop is Class 100,000, while for plastic, our factory has Class 10,000, or even Class 1,000 clean workshops.

Q: Can you design the LSR molding silicon optics?

A: For now, we just do OEM designs. Our team is unable to do the product design.

Q: What should I offer to custom LSR silicone optics?

A: Pls. offer us 3D drawing and performance requests.

Q: Can I get samples of injection molding silicon optics?

A: Yes, samples can be provided for quality checking, shipping costs to be paid by customers.
