Machines & systems, Entire overview Laser marking of plastics has many advantages of traditional marking methods like ink, dyes and paints. Since lasers with different wavelengths are available, the wavelength can be optimized for the respective material. Our plastic marking systems come in a variety of sizes … Press releases, 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. Do you want to keep or change the selection? The marking process produces such … Discoloration is caused by the break-up of chemical compounds. 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 … These lasers often achieve better results than standard systems with wavelengths of 1,064 or 1,030 nm. For laser marking plastics, the laser selectively melts the matrix material, creating gas bubbles which become trapped during cooling. The varying properties and additives in plastics often require individualized marking solutions. “Laser Marking” of plastics is a noncontact digital process whereby indelible information is applied onto a target substrate surface with minimal material penetration. 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.
