The laser marker uses a laser beam to make permanent marks on the surface of various materials. The effect of marking is to expose deep material through the evaporation of surface material, thereby engraving exquisite patterns, trademarks and text. laser marker are mainly divided into CO2 laser marker, semiconductor laser marker, and fiber laser marker. And YAG laser marker, laser marker is mainly used in some occasions requiring finer and higher precision. Used in electronic components, integrated circuits (IC), electrical appliances, mobile communications, hardware products, tool accessories, precision equipment, glasses and watches, jewelry, auto parts, plastic buttons, building materials, PVC pipes.
