Plastic Laser Welding for Automotive Door Check Strap Housings

Date：2026-04-23 13:50 Source：daokedao Browse：21

Automotive door check straps control door opening angle, requiring high strength, wear resistance, and anti-vibration performance, protecting internal components from dust and moisture. Traditional ultrasonic welding introduces vibration that misaligns internal mechanisms, leading to door sagging and abnormal noise, while mechanical assembly has poor durability. DaokeDao laser welding adopts a non-contact, zero-vibration process, suitable for PA and ABS check strap housings, forming a continuous weld with shear strength ≥19MPa. The narrow heat-affected zone (≤0.3mm) ensures dimensional accuracy (tolerance ≤±0.02mm), ensuring smooth door operation. The weld meets IP65 protection grade, blocking dust and moisture, adapting to harsh vehicle environments. The equipment supports flexible production, quick parameter switching for different door models, cycle time 7-10 seconds per unit, suitable for mass production of door component suppliers, reducing product failure rates.
