Laser Marking and Engraving Terms

Engraving

Engraving-Example.jpgA process where material is actually removed or vaporized, then recast to create depth in the material. The measured depth for engraving is greater than one thousandth of an inch.

Etching

Ablation

Ablation Example.jpgThe process of removing coatings like anodization, black oxide, plating, masking, or insulation via irradiation from a laser beam.

Annealing

Anneal Example.jpgThe process by which the surface of a material is heated to just below its melting point in order to create oxide layers on the surface.

Color Change

Color Change Example.JPGThis mark type uses the energy of the laser beam to alter the molecular structure of the piece, making a visible change in the color of the plastic substrate without damaging the surface of the material.

Foaming

Foaming Example.jpgThis mark uses the energy of the laser beam to alter the molecular structure of the piece, making a visible change in the color of the substrate, without damaging the surface of the material. Foaming is similar to color changing, however the process actually raises the level of the material so it appears like a foam on the surface of the plastic.

Polish (Burnish)

Polishing Example.jpg

Polishing is a process where the laser’s intensity is reduced to ensure the lightest marking intensity possible. This creates a mirror-like oxidized surface layer without removing any actual surface material.
