Laser Engraving

Laser engraving 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, and more.


Laser engraving is a process that vaporizes materials into fumes to engrave permanent, deep marks. The laser beam acts as a chisel, incising marks by removing layers from the surface of the material. The laser hits localized areas with massive levels of energy to generate the high heat required for vaporization.


Laser engraving technology is typically used to engrave metal workpieces or wood that will be exposed to various types of wear or surface treatments.

The most outstanding feature of this process is its ability to engrave 2D codes that keep high readability rates after post-process treatments. Those treatments can include shotblasting, e-coating and heat treatments, addressing the most complex traceability issues.
