Paint stripping of wheel calottes

THE CONVINCING ALTERNATIVE FOR CONVENTIONAL PROCESSING METHODS FOR PAINTED SURFACES OF YOUR WHEEL CALOTTES IN THE PROCESS OF PAINTING YOUR RIMS

The current coating process of wheels usually includes the performance of four steps:

masking, painting, drying and unmasking.

Before painting the rim, a robot inserts the balls or plugs in the holes (wheel calottes). These need to be removed again after the painting process. Afterwards the balls/ plugs must be cleaned and replaced from time to time.

In the course of laser processing, the up to now performed steps are reduced to three steps:

painting, drying and laser stripping.

The results are:

  • clean transitions (from the coated to the de-coated area)
  • no fraying of the coating and
  • clean metallic contact surfaces of the wheel calotte.
  • There will be no reworking.

The product quality is increased immensely; some companies stipulate the de-coating by laser during the coating process for certain types of wheels becuase no other treatment achieves simliarly precise, clean edges.
The wheel hub can be treated as well.

The SLCR system includes a paint stripping system which can be designed with up to three stations for 600 / wheels / h (5 calottes). The SLCR laser systems can be operated as standalone systems as well as be integrated in existing production lines.

 

The system is part of the registered utility model 20 2017 107 037.9

Overall, the paint stripping of wheel nut calottes by SLCR lasers offers numerous advantages, for example:
 

  • Elimination of the process steps "Masking and unmasking"
    • no balls or plugs
    • no cleaning of residues
  • Improved painting quality

  • Reduced operating and production costs (plug purchase and cleaning)

  • Reduced work effort (expensive masking and unmasking are eliminated)

  • Highest processing quality

  • Contactless and gentle processing

  • Optimal transition to the coated area

  • Reliable reproducibility of the work results (improvement over the wear of the plugs)

SLCR Lasersystems for surface treatment

Industrially fully developed and proven SLCR laser systems impress with their excellent machining quality, reliable reproducibility of the work results and economic efficiency. The removal of organic coatings by laser opens up innovative solutions and the possibility to edit surfaces directly in the production line. The SLCR technology is also setting new standards in rim manufacturing. Due to de-painting of the wheel nut calottes by SLCR laser technology, the complex masking of this functional area is eliminated. This saves money and improves product quality!
