Testing system, plastic headlight lenses

Portfolio: Measurement and Test Engineering
Industries: Automotive


For the ZKW Group, HEITEC develops and constructs innovative, fully automatic production lines with ultra-modern automatic testing systems for plastic headlight lenses.


The automatic testing system, equipped with state-of-the-art sensors and image processing components, ensures 100% optical testing combined with surface and volume inspection for plastic headlight lenses. Light transmission testing and dark-field testing reveal faults such as dark points, inclusions, streaks, air pockets, scratches and flow lines. The system is designed to allow four different lens types to be tested with no change of tool.
