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