2022-12-1934800In laser marking, the extremely thin laser beam after focusing is like a cutter, which can remove the material on the surface of the object point by point. Its progressiveness lies in that the marking process is non-contact processing, which does not produce mechanical extrusion or mechanical stress, so it will not damage the processed object; Beca...
2022-12-1934800The basic principle of laser marking is that a high energy continuous laser beam is generated by a laser generator. The focused laser acts on the substrate material, making the surface material melt instantaneously, or even vaporize. By controlling the path of the laser on the material surface, the required graphic marks are formed. Three methods o...
