Laser Paint Stripping and Laser Coating Removal
LASER PAINT STRIPPING & LASER COATING REMOVAL
Paint systems designed for the most demanding climates and operating conditions are not meant to be removed easily, but in the assembly and bonding processes selective paint removal is required. Read more on how lasers eliminate the messy and expensive masking before dip or spray coating.
SELECTIVE LASER COATING REMOVAL AND LASER PAINT STRIPPING
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.
SUCH A MASKLESS LASER DECOATING HAS MANY ADVANTAGES
simple blanket coating without masking
elimination of manual masking / demasking operation or expensive masking automation
consumable free process - no tapes, no films
combination with oxide removal or surface structuring for enhanced bonding performance TYPICAL APPLICATION AREAS FOR LASER PAINT REMOVAL AFTER MASKLESS COATING INCLUDE
Welding preparation e.g. in manufacturing of EV battery trays
Decoating of bearing bushes e.g. in wheel manufacturing
Ground connection terminals e.g. for cabinets or household goods
