Laser Marking

Laser marking on plastics is the largest body of work on this site: how fiber, UV and CO2 lasers interact with polymers, why some resins mark with no help and others need laser-sensitive additives or masterbatch, and how to set the process window for permanent, high-contrast marks. The articles below cover specific materials such as nylon, ABS, polycarbonate, PPS and polyolefins, marks on textured and matte surfaces, the choice between marking, engraving and etching (and cutting versus engraving), process parameters, troubleshooting, and the compliance side of UDI and traceability codes. Start with the laser marking services page for the engineering offer, or use the laser marking chart to check a resin before you read further.
