The majority of plastic materials can be marked with excellent results. Using different wavelengths and different laser sources, depending on the type of plastic you wish to mark, permanent, quick, high-quality, and traceable markings can be achieved in seconds.
You can easily mark on keyboards, electronic components, automotive parts, printed circuit boards, plugs, id tags, and tools.
It is important to note that different plastics react differently to the laser marking process and therefore you should always test a material sample
In the foaming process, the laser beam melts the plastic surface on a localized area and then creates small gas bubbles on the material after it cools down. The gas bubbles reflect light in a diffused way. Afterwards, the gas that has accumulated inside increases the volume of the material, creating a foamed plastic. The part that has been laser marked looks brighter than the area around it and appears to be upraised from the surface achieving optimal results.
Laser carbonization always produces a darkening of the material that has been marked. Plastic bonds are broken and carbon is released during this process. The resulting discolouration ranges from grey to bluish-grey to black. Carbonization is used on clear plastics and organic materials (paper, packaging, wood and leather), with a resulting chromatic effect that changes from clear to dark.
Plastics absorb the light from the laser. Colour pigments and carbon in plastics are destroyed and vaporize as a result of localized heating. Depending on the composition of the material, the discolouration may be clearer or darker. The dark plastics turn white where they were marked while clear plastics turn grey or black.
