Principle of laser marking machine

Laser marking is to use a laser beam to make permanent marks on the surface of various substances. The effect of marking is to expose the deep material through the evaporation of the surface material, or to "carve" the traces through the chemical and physical changes of the surface material caused by the light energy, or to burn off some materials through the light energy, so as to show the required etched patterns and characters
