Plastic Laser Welding for Automotive Interior Ambient Light Housings

Date：2026-03-20 14:30 Source：daokedao Browse：5

Automotive interior ambient lights enhance cabin comfort and aesthetics, requiring high optical clarity, uniform light output, and seamless design. These housings are made of transparent plastics like PMMA and PC, demanding a welding process that preserves transparency and avoids visible welds. Traditional ultrasonic welding leaves visible seams, while hot plate welding may cause material yellowing. DaokeDao laser welding produces seamless, invisible welds that maintain high transparency (transmittance ≥93%) and uniform light output (uniformity error ≤4%). The non-contact process avoids surface scratches and material yellowing, preserving long-term optical performance. It forms a strong bond (shear strength ≥16MPa) that withstands vibration and temperature changes (-30°C to 70°C). Our systems support complex 3D light housing designs, with fast cycle times (8-11 seconds per unit) and high-volume production (up to 125 units/hour). By improving ambient light quality, DaokeDao laser welding helps automakers enhance vehicle interior aesthetics and user experience.
