Caddy rear axle, VW Braunschweig

At the Volkswagen plant in Braunschweig, we implemented an automated production line for VW Caddy rear axles. The sequence includes incoming paint racks, transfer of the parts to the processing machines, and the output of the finished parts. The system checks quantities and sorts out defective parts; a job manager optimally adjusts the production sequence.
