Laser marking is the use of a laser beam to permanently mark the surface of various substances. The effect of marking is to expose deep substances through the evaporation of surface substances, or to "engrave" traces through chemical and physical changes in surface substances caused by light energy, or to burn off some substances through light energy, displaying the desired etched patterns and text.

A laser marking machine uses a laser beam to permanently mark the surface of various substances. The effect of marking is to expose deep layers of material through the evaporation of surface materials, thus carving exquisite patterns, trademarks, and text. Laser marking machines are mainly divided into CO2 laser marking machines, semiconductor laser marking machines, fiber laser marking machines, and YAG laser marking machines. Laser marking machines are mainly used in situations that require more precision and precision. Applied to electronic components, integrated circuits (ICs), electrical appliances, mobile communication, hardware products, tool accessories, precision instruments, glasses and watches, jewelry, automotive accessories, plastic buttons, building materials, PVC pipes.
