Fully automatic and enviromentally friendly paint stripping of skid cross member connection by means of inliner eddy current

Another German OEM has chosen the eddy current paint stripping system for the maintenance of cross member connections of the skids of its E-Coat and painting line. Pursuant to the manufacturing conditions at BMW Leipzig, we suggested the implementation of an inline paint stripping concept.


Coating OFF Inline for cathodic dip painting skid pins

In the cathodic dip painting of car bodies, painting of the tools necessary for the process such as the body skid is unavoidable. The contacts must be decoated regularly to maintain the electrical conductivity of the skid to the body.

The eddy current process enables inline decoating in every run through, this achieves an optimum process stability in cathodic skid painting.

The skids can stay in circulation much longer without having to be taken out of the line for external overall decoating. External decoating costs as well as transport and logistics for this are reduced considerably.

Burning of the bodies at the contacts to dissolving of the body in the cathodic skid painting bath with the associated belt downtimes can therefore be reliably avoided.

A decoating plant consists of an eddy current station, a brush station, the control unit and air filtration which are interconnected by energy supply lines.

Decoating by the eddy current process is suitable for most types of paints, rubber, adhesives and foams and offers the user several advantages.

No fresh water and waste waster pipes or chemicals are required. The same applies for washing or phosphatising processes. The system can be integrated into existing painting lines, reduces the energy consumption and enables decoating of partial areas.

The system has an amortisation time of less than one year for automobile manufacturers. This was achieved by the improved process stability and therefore less touching up to be done on cathodic skid painted bodies.
In addition the external decoating costs as well as transport and logistics for this are considerably reduced. The production costs could also be reduced by dispensing with manual cleaning times.
