Premium Polycarbonate Headlight Lens Supplier | Geqin Auto Parts

As a professional polycarbonate headlight lens supplier, Foshan Geqin Auto Parts provides high-quality optical solutions for modern vehicle lighting systems. Our PC lenses offer exceptional impact resistance combined with 90%+ light transmission for optimal performance. The lenses are manufactured using precision molds with optical-grade surface finishes (Ra <0.05μm). We utilize UV-stabilized PC formulations that maintain clarity and prevent yellowing under prolonged sun exposure. Our production process includes stress-relief annealing to ensure long-term dimensional stability. The lenses feature precision-molded alignment elements for accurate positioning in headlight assemblies. We offer various surface treatments including abrasion-resistant hard coatings (up to 4H pencil hardness) for exterior applications. Our quality control includes comprehensive photometric testing to verify beam pattern compliance with ECE/SAE standards. The lenses demonstrate excellent resistance to automotive chemicals including washer fluids and road salts. We can produce lenses with complex geometries including integrated light guides or decorative elements. All lenses undergo rigorous environmental testing including thermal cycling and vibration resistance evaluations. Our technical team provides full support from design concept to production validation.
