How to Laser Marking on Film and Paint

December 24th, 2021 | Comments Closed | Blog

Laser marking on films has completely replaced screen printing in the production of parts in many areas of application, primarily for the so-called “Day / Night”. With the laser, the amount of material is removed and therefore the engraving depth can be precisely controlled. Laser marking can also accurately set the size of the engraving lines and improve the detection of angles, which will also greatly increase productivity лазерная гравировка на стекле.

Laser Marking on Paint

The laser is capable of very accurately removing and carbonizing thin layers of paint on various materials. You can mark paint in three different ways:

• Ablation: the laser beam removes paint from the surface of the material partially or completely, depending on the desired effect, creating a depression in this area.
• Carbonization: in this case, the laser beam burns the paint and, as a result, makes it darker.
• Toning: This is the rarest case that depends on ink and laser and causes discoloration without ablation or carbonation.

Laser Marking on Films

Some types of films are directly marked with a laser, and some types of films can also be cut. An example of such laser marking is peel-off film marking, which allows marking with very high speed and contrast and simultaneously cutting off for final use by the end-user. During laser cutting, there is no mechanical effect on the film, because the process proceeds without touching it, and the result is much higher quality. The laser allows you to cut accurately and in record time, leaving clean-cut edges. Another advantage of the laser is its performance when working with multilayer films, as it allows you to cut several layers at the same time.

Application on Day / Night films

The so-called Day / Night laser marking application is applied to various types of backlit plastic components. This process is widely used in the automotive industry (for example, for switches and interior buttons of automobiles) and in consumer electronics. The laser performs a selective ablation process, removing surface layers from the part until the desired effect is achieved.
