Laser marking is a marking method that uses a high-energy-density laser to locally illuminate a workpiece, causing a chemical reaction of the surface material to vaporize or undergo a color change, thereby leaving a permanent mark.
The focused ultra-fine laser beam is like a tool, which can remove the surface material of the object point by point. Its advanced nature is that the marking process is non-contact processing, without mechanical extrusion or mechanical stress, so it will not damage the processed object. Since the laser has a small size after focusing, the heat-affected area is small, and the processing is fine, it is possible to perform a process that cannot be achieved by conventional methods.
