摘要

Torsional Ultrasonic Welding. Faurecia, Nanterre, France, is aproducer of bumpers employing the Soniqtwist process of torsional ultrasonic welding supplied by Tclsonic AG in Bronsch-hofen, Switzerland. The company uses this technique to integrate into varnished bumpers sensor fixtures of polypropylene (PP), some of them including shares of ethylene propylene dien rubber (FPDM), serving for the purpose of distance control and parking assistant. This way, also the headlamp cleaning units are fixed, which sit in the body below the Xenon headlamps. This welding process generates weld lines so strong they meet strength requirements of 250 to 300 N. The sonotrode does not penetrate the bumper's lower material layers during welding.
