Daoke Dao Laser Welding for Automotive Door Control Module Plastic Housings: Waterproof & Durable

Date：2026-02-25 14:47 Source：daokedao Browse：27

Automotive door control modules are installed in door panels, and their plastic housings require waterproof and durable welding to adapt to the humid environment inside the door and long-term use. Traditional welding has poor sealing and weak welds, leading to water intrusion and module failure. Daoke Dao plastic laser welding equipment provides comprehensive protection for door control module plastic housings. The hermetic weld seam achieves IP65 waterproof standards, effectively blocking rainwater and moisture intrusion. Suitable for ABS and PC plastic materials, the welds have high tensile strength (≥25MPa) and impact resistance, ensuring the module can withstand long-term vehicle vibration and minor collisions. The low-heat process avoids damage to internal control circuits. Compliant with IATF 16949 standards, it integrates into automated door panel assembly lines with a welding cycle of 10 seconds per unit. The equipment supports customized plastic housing sizes, adapting to different door designs. Daoke Dao helps auto electronics manufacturers improve product durability. Contact us for waterproof test reports.
