Laser engraving, which is a subset of laser marking, is the practice of using lasers to engrave an object. Laser marking, on the other hand, is a broader category of methods to leave marks on an object, which also includes color change due to chemical/molecular alteration, charring, foaming, melting, ablation, melting, and more.
The technique does not involve the use of inks, nor does it involve tool bits which contact the engraving surface and wear out. These properties distinguish laser engraving from alternative engraving or marking technologies where inks or bit heads have to be replaced regularly.
Laser Marking is focused on providing top value solutions for automotive, metal tools, medical, electronics and packaging. Datalogic offers high level technology in marking equipment based on FIBER, DPSS, GREEN, UV and CO2 lasers.
