Laser marking on plastic Speaking about plastics means referring to derivatives from very different chemical compositions, which influence the performance of the processes applied to them, including … Laser marking can be one of the most successful ways to mark or engrave plastics -- over labels, printing, and other alternatives -- when you are using the right type of laser marking machine for your application. Our high-performance engraving materials are offered in over 300 color combinations. Laser engraving plastic demands both scientific and creative approach. Buttons in vehicle interiors are an example of markings achieved by layer ablation. One of the key features that makes plastics so difficult to mark successfully is the wide variety of compounds available, including polycarbonate, polyethylene, and silicone; furthermore, common fillers, extenders, and additives as well as colors. The laser radiation of the Endurance semiconductor (diode) lasers melts the upper layer of the processed material, which allows to engrave or cut samples of acrylic, plastic, and rubber up to 10 mm thick. Advantages of TRUMPF machines, Entire overview Laser inscriptions on plastics neither fade nor rub off so remain perfectly legible even after years. 020 6675 9899, pdf - Non-contact laser marking is very fast as well as abrasion, heat and acid resistant, and many different plastics can be marked or engraved with a laser. The laser marking of plastics basically involves three separate processes: changes in color, alterations to surfaces and the ablation of layers.>. To achieve high legibility and marking quality, it is recommended to mix laser-sensitive additives into some industrial plastics. Laser Printing on Plastic Our laser marking additives can be used in polyolefins like PP, HDPE, PS, ABS, PC, TPU, PET, PBT, Nylon, PVC and TPE etc. VCSEL solutions & photodiodes, Entire overview These lasers often achieve better results than standard systems with wavelengths of 1,064 or 1,030 nm. Since lasers with different wavelengths are available, the wavelength can be optimized for the respective material. Online Magazine, Entire overview 7 MB, Entire overview VCSEL solutions & photodiodes, Entire overview Advantages of TRUMPF machines, Entire overview Fiscal year figures 2019/20, Laser welding systems and the arc welding cell, Entire overview TRUMPF provides you with a complete solution for your specific application. Polyethylene is an important plastic used in packaging and bottling industries. Applications, Entire overview Cold and non-contact laser marking means that the component surface remains virtually unaffected. Please note that up until revocation, the legal validity of consent-based processing remains unaffected. This behaviour is also used in the laser welding of plastics, during which one welding partner absorbs the laser beam and the other welding partner is transparent for the laser beam.

The low heat conductivity in plastics means low energy losses during marking. Services, Entire overview UV Laser Marking Machine : Well-suited for marking heat-sensitive materials, including a number of plastics, from HDPE and silicone to polycarbonate and polyethylene. As the material does not burn or carbonize, it is referred to as "cold marking" with high surface qualities. For day and night designs, lasers with high pulse-to-pulse stability are available to ensure precise and homogeneous layer ablation. Even after multiple cleaning cycles, these scales remain clearly legible and are highly resistant to temperature and environmental factors. The varying properties and additives in plastics often require individualized marking solutions. Laser marking plastics offers fast, non-contact processing which helps maintain the integrity of the material. Laser marking on plastics in the medical and automotive industry Its versatility and its relatively low cost make plastic a universal material. How do I Ensure High-Quality Laser Marks?
