Laser Marking Applications

Generally, there are four different kinds of laser marks: annealing, engraving, etching, and carbonization. They are defined by whether or not material is displaced during the laser marking process and how much material is displaced during the reaction.

When laser marking, a laser beam is concentrated on the surface of a part to generate heat. Once the beam hits the material's surface, the material converts the energy into heat after absorption. The heat produces a permanent mark, either by discoloring the surface of the part or displacing material, creating depth. 

Laser marks can be used to create a company logo, a manufacturing code, a date code, a serial number, a 2D data matrix mark, or any type of mark required for regulatory compliance.
