Now it's time for some colour.
First the car bodies must be degreased and other dirt removed. As part of the pre-treatment, aluminium parts are lightly sandpapered, in order to enable a perfect coating. The bodies receive their first corrosion protection in a CPD bath (cathodic dip coating).
Then the base coat is applied. This filler smoothes out any unevenness. After the base coat and the final coat, the clear coat is applied to give the bodies their shine.
A paint shop incorporates conveyor technology, various dip tanks as well as numerous robots for applying the individual paintwork. In between, there are evaporation zones and drying and baking chambers. Heat generation, water treatment, paint tank maintenance, exhaust air and fresh air supply are absolutely vital for reliable operation.
Here sensors from ifm, with their high standards of repeatability and switch point stability, help the operator to ensure the high quality of the painting process in series production.
