In many industries surfaces are being coated with cathodic dip (CDC) or powder coatings. Such paints provide the durability and anti-corrosion properties needed in manufacturing of cars or other surfaces facing outdoor climate.
However, certain areas of such parts need to be free of any coating to assure good welding or adhesion behavior, tight mechanical fit or a blank metal surface for electrical connections.
A common process to avoid coatings on these bond interfaces is to mask such areas before coating and remove the masking afterwards. This is a tremendous waste of resources, difficult to automate and environmentally questionable.
The use of laser paint stripping systems allows to coat the parts without masking and selectively remove the coatings on the bonding interfaces in a subsequent process.
