Are there different kinds of laser engraving?
Stain Mark / Surface Mark: On metals and a few plastics, this is generally a permanent dark mark with no surface texture. This is often utilized on medical components and devices that must have a non-disrupted surface, or, in the case where customers want the smooth look and feel of the marking. Dark Laser Engrave: In this case, your gear is actually engraved past the surface leaving an oxidized, dark, textured mark, the laser vaporizes material. This procedure requires wiping vaporized material away from the engraving. Clean up passes may be run to remove the dark oxidization color from the engraving. “White” or “Frosted” Etch: Particularly used on highly reflective and polished parts the laser lightly disrupts the surface of the component, leaving a mark that appears white or “frosted”. Deep Engrave: Deep engraving is a process where the laser engraves to depths greater than .002″. A depth of .030 can be achieved with deep engraving, with the cost depending on the depth required.
