Principle of Laser Marking
Laser marking technology is a new type of non-contact, pollution-free and damage-free marking process. It integrates laser technology, computer technology and mechatronics technology. It is currently the most widely used advanced manufacturing technology in laser processing technology. The principle of laser marking is to use a high-energy-density laser to locally irradiate the workpiece, so that the surface material vaporizes or undergoes a chemical reaction of color change, thereby leaving a permanent mark.
