Plastic Laser Welding for Automotive Door Window Regulator Housings

Date：2026-04-16 14:05 Source：daokedao Browse：3

Automotive door window regulators control the lifting and lowering of door windows, requiring compact structure, good sealing, and anti-vibration performance, protecting internal gears and motors from dust and moisture. Traditional ultrasonic welding introduces vibration that misaligns internal components, leading to jamming and abnormal noise, while mechanical assembly has poor durability. DaokeDao laser welding adopts a non-contact, zero-vibration process, suitable for PA and ABS regulator housings, forming a continuous and dense weld with shear strength ≥17MPa. The narrow heat-affected zone (≤0.3mm) ensures the dimensional accuracy of the housing (tolerance ≤±0.02mm), ensuring smooth window lifting and lowering. The weld meets IP65 protection grade, effectively blocking dust and moisture, adapting to harsh vehicle environments. The equipment supports flexible production, with quick parameter switching for different vehicle models, cycle time 7-10 seconds per unit, suitable for mass production of door component suppliers, reducing product failure rates and improving user experience.
