High-Quality PC Plastic Parts for Vehicle Lighting | Geqin Auto

Our PC plastic parts for vehicle lighting combine optical performance with automotive-grade durability. These components utilize high-quality polycarbonate formulations with 90%+ light transmission and excellent UV stability. We manufacture complex optical elements including headlight lenses, light guides, and reflector housings with precise optical surfaces. The parts feature impact resistance exceeding 60 kJ/m² (IZOD) to withstand stone impacts on roadways. Our processing techniques minimize internal stresses to prevent stress cracking in harsh environments. The components maintain dimensional stability across automotive temperature ranges (-40°C to 120°C). We offer various surface treatments including hard coatings for abrasion resistance and anti-fog treatments for interior surfaces. Our quality control includes photometric testing to verify optical performance meets regulatory standards. The PC parts demonstrate excellent resistance to automotive chemicals including washer fluids and road salts. We can produce components with integrated mounting features for simplified assembly. All parts undergo rigorous environmental testing including thermal cycling and vibration resistance evaluations. Our technical team can develop custom solutions for unique lighting applications or styling requirements.
