Torsional Welding of PDC Sensors to Thin Wall Fascia


This is the first application of torsional welding (spin & ultrasonic welding combined) on automotive fascias. It allows welding of PDC brackets without localized thickening of wall stock on 2.5 mm, thin wall, molded fascias. An adjustable TPO material with high melt flow, high stiffness/ impact allowed for less material to be used resulting in a 10% reduction in mass for a 7% weight savings with $122,000 direct cost savings in three years. Cycle times were improved and there was no weld read through resulting in a quality appearance. Future applications or this process include fascia support brackets, fog brackets and more.
