Plastic Laser Welding for Automotive Interior Roof Light Housings

Date：2026-04-15 09:33 Source：daokedao Browse：24

Automotive interior roof lights provide cabin lighting, requiring seamless appearance, reliable sealing, and uniform light emission, adapting to cockpit temperature changes and vibration. Traditional ultrasonic welding affects internal lamp beads, leading to uneven light emission, while adhesive bonding has poor durability. DaokeDao laser welding adopts a low-heat non-contact process, zero damage to internal LED lamp beads, ensuring uniform light output (uniformity error ≤4%). The weld is seamless and beautiful, consistent with the roof texture, enhancing interior refinement. The sealed structure (IP65 rating) blocks dust and moisture, maintaining long-term lighting stability. The equipment supports miniaturized housing welding, cycle time 7-10 seconds per unit, suitable for mass production of interior accessories suppliers, helping automakers improve interior detail quality and user experience.
