Laser Marking on (Multilayer) Lacquers -
Day & Night Marking
Day/night design switches in a component take-up system
Challenging coating layer removal on plastic parts with multilayer lacquers. The individual color or coating layers were removed from the component with a high degree of precision, in order to ensure that the basic material to be backlit becomes visible. The adjustment that is carried out on different coating layers and colors is implemented with application-specific laser parameters that are easy to adjust.
The individual switches are automatically detected directly in the take-up process by means of a high-precision, camera-guided coating layer removal procedure, after which they are processed.
Red plastic button
Extremely challenging, since the complicated lacquer removal takes place on a red machine button. The color and coating removal on the red plastic is technically very challenging because the red lacquer that is to be removed is not optimally absorbed in case of infrared lasers. If one overcomes this challenge, one can say that one has achieved a very high-contrast and extremely effective marking.
Silver-gray painted control element made of plastic
Coating layer removal from a painted plastic component. The upper, in this case silver, layers of color/lacquer layers are removed with precision using lasers; the orange layers underneath are visible as markings.
