A marking method that uses the laser generated by the laser marking machine to irradiate the workpiece locally, so that the surface material vaporizes or undergoes a chemical reaction of color change, thus leaving a permanent mark. Its working principle is that a high-energy continuous laser beam is generated by a laser generator. When the laser acts on the printed material, the atoms in the ground state jump to a higher energy state; Atoms in a higher energy state will soon return to the ground state. At this time, excess energy will be released in the form of photons or quanta, which will be converted from light energy into heat energy, so that surface substances will melt or even vaporize instantly, thus forming graphic traces.
