Location: Michigan, USA Customer: Suppliers of automotive welded assemblies Growth driver: Elimination of costly hand sorting Case study Requirement Metal stampers fabricating welded assemblies for automakers need to weld studs to sheet metal parts for assembly. Occasionally a stud with no threads gets welded to a part, requiring costly hand sorting and rework. Sheet metal stampers attempted to use technologies like laser or proximity sensors to detect problems, but while they could often detect the presence of a stud, they were not sensitive enough to detect threads. The industry needed a detection method sensitive enough to detect missing threads on a stud and durable enough to withstand extreme operating conditions. Solution The Automation Solutions experts at IMI Precision Engineering used their unique, proven steel-faced inductive sensor technology to develop the only stud detector in the industry with sufficient sensitivity and range to detect both the presence of studs and whether they are threaded or not. The IMI Norgren Stud Thread Detector helps users eliminate scrap caused by missing or unthreaded studs. It also eliminates hand sorting, a quality control process that can cost an average of $20,000 every time it is required.
