The most common laser marking machines on the market are mainly CO2 laser marking machines and YAG laser marking machines. Later, YAG laser marking machines were gradually replaced by semiconductor laser marking machines, becoming the model with the largest market share of laser marking machines. In addition, there are high-end end pumped laser marking machines, fiber laser marking machines, ultraviolet laser marking machines, and so on.

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.
