“Precise paint removal” .
One of the significant Hungarian paint manufacturers undertook the placement of lighting signs on painted plastic casings.
The client’s problem:
All of us know the pictograms on the buttons in the cars which are visible day and night. Such pictogram captures are made by painting the transparent plastic part to black, then the required figure or text is engraved on the surface by laser. Laser vaporises the paint layer, but does not damage plastic. Thus, in the dark, a LED light placed behind the cover lights the button and the information becomes visible. Great quality dye houses rarely own precision laser engraving machines, therefore they have to find a servicing partner for such works.
Folprint Laser Engraving’s solution
Folprint Laser Engraving experts ran tests on the provided samples and searched for the ideal settings in order to remove paint without damaging the transparent plastic surface which later would be lit by a LED lamp. Series production started following the tests and the client returns to us regularly for laser marking works. In the below picture the battery icon is being marked by a laser.
If only the upper layer has to be removed, in case of specific surfaces, laser engraving is the best solution.
