According to the difference of lasers, Laser marking machines comprise
lamp-pump YAG laser marker,
DP Diode side-pump laser marker,
fiber optic laser marking system,
co2 laser marker etc. YAG, DP, fiber-optic marking machines are mainly used in marking many materials, such as Metals, alloys, oxides, ABS, epoxy resin, printing ink etc; while co2 laser marker is mainly application in wood, paper, PVC, ABS, epoxy resin, EP, Acrylic, leather, glass and so on.
The marking machine is using laser beam to reveal the substance in-depth through evaporating the substance on the surface, or make imprints "engraved" after chemical or physical change of the substance on the surface happen becauce of the energy of the ray, or make figures and characters we need after the beam burns part of the substance. its advantages are Non-contact, no supplies, high precision, convenient, flexible, high-speed and environmental protection.
