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 requiring more precise and higher precision. Used in electronic components, integrated circuits, electrical appliances, mobile communications, hardwre products, tool accessories, precision equipment, glasses and watches, jewelry, auto parts, plastic buttions, building materials.
