Thin-wall Technology Bumpers Customer Case

Lightweight construction is an important trend in the automotive industry. As well as cutting down on weight, it enables significant cost savings. However, traditional welding methods struggle to meet requirements in applications which involve wall thicknesses of less than 3 mm and demand high-quality Class A surfaces. It is against this background that torsional ultrasonic technology, often also referred to as high-frequency friction welding, is gaining increasing acceptance as a joining process of the future. The SONIQTWIST® technology developed by Telsonic is now being used in series production in the automotive industry: Magna Exteriors, a multinational tier 1 supplier of exterior products and systems, has been using SONIQTWIST® to produce bumpers in thin-wall technology since the middle of 2017.
