The effect of marking is to expose the deep material through the evaporation of the surface material, so as to engrave exquisite patterns, trademarks and characters. Laser marking machines are mainly divided into CO2 laser marking machines, semiconductor laser marking machines, and fiber laser marking machines. Used in electronic components, integrated circuits (IC), electrical appliances, mobile communications, hardware products, tool accessories, precision instruments, glasses and clocks, jewelry, auto parts, plastic buttons, building materials, PVC pipes.
