Plastic

        Lasers mark plastic components not only permanently and flexibly, but also very environmentally and material friendly. This is due to the fact that - compared to conventional marking procedures - no templates or consumables such as ink are required. Laser markings on plastic surfaces are always smudge and abrasion resistant.

        The key to laser marking plastics is achieving sufficient absorption of the laser beam into the material. In metals, most of the beam is reflected, while in plastics, transmission, diffuse reflection, and absorption are more important. The low heat conductivity in plastics means low energy losses during marking. Plastics can therefore be marked much faster than metals.

        Plastics are materials that pose several challenges to many marking systems. The main objective of marking systems is the long-term legibility of markings, but ink, for example, has inherent limitations. Moreover, not all plastics are the same. The varying properties and additives in plastics often require individualized marking solutions. Lasers are much more flexible in coping with such challenges, tolerating even minor surface soiling.The laser achieves even the most intricate markings which are high-contrast, clean, and without any smudges.
