The laser marking machine uses a laser beam to make permanent marks on the surface of various materials. The effect of marking is to expose deep materials through the evaporation of surface materials, thereby engraving exquisite patterns, trademarks and texts. Laser marking machines are mainly divided into CO2 laser marking machines, semiconductor laser marking machines, and fiber laser marking machines. the current laser marking machine 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.
