The BMW Group Plant Leipzig is introducing a terahertz-based measurement system for plastic exterior components in series production. At the heart of the system is the terahertz measurement system Irys, developed by das-Nano specifically for industrial inline inspections. The system enables contactless, non-destructive measurement of multi-layer paint systems and delivers real-time data. Sensors mounted on two robots in the existing end-of-line measurement cell are automatically and precisely positioned in relation to the component, where they measure the thickness of the individual paint layers. Measurements take only seconds and achieve accuracy down to the micrometre level.
