Optical and mechanical measuring systems

With our high-performance sorting systems, we check your fasteners in every imaginable way.
In doing so, we draw on the expertise of Vester / Kistler , with whom we have been developing and using sorting systems for more than 30 years. We also rely on systems from LAW-NDT . Recently, CCM has also been our partner for sorting technology.
