Plastic Laser Welding for Automotive Seat Belt Buckle Housings

Date：2026-04-15 09:25 Source：daokedao Browse：5

Automotive seat belt buckles are safety-critical components, requiring high strength, wear resistance, and reliable locking performance, withstanding high impact forces (up to 5500N) during collisions. Traditional mechanical assembly has weak points, while ultrasonic welding may cause internal component deformation, leading to locking failure. DaokeDao laser welding creates a continuous, high-strength weld for PA66-GF and ABS buckle housings, tensile strength ≥34MPa, ensuring structural integrity during collisions. The non-contact process avoids vibration damage to internal locking mechanisms, ensuring smooth locking and unlocking operation. The weld has excellent wear resistance, withstanding repeated use without loosening, and meets IP65 protection grade, blocking dust and moisture. The equipment supports high-volume production, with a cycle time of 6-9 seconds per unit, pass rate ≥99.5%, complying with automotive safety standards, helping automakers enhance passenger safety and meet regulatory requirements.
