The difference of laser marking machines: Fiber, CO2 and UV(图1)

Laser marking machines can be roughly divided into three types, according to the different light sources. Today we will briefly understand their basic knowledge.

Fiber laser marking machine

Fiber laser marking machine is a marking equipment that uses a fiber laser to strike a laser beam on the surface of a variety of different materials. The surface material is physically or chemically changed through light energy, thereby engraving permanent marks such as patterns, trademarks and texts. . Its components include: fiber laser, laser galvanometer, field lens, industrial computer, display, cabinet, control switch, power supply, ruler and lifting shaft, etc. MOPA laser marking machine also belongs to the type of fiber laser marking machine.

CO2 laser marking machine

The CO2 Laser Marking Machine uses a gas laser with an infrared light band of 10.64μm. The CO2 gas is charged into the high-pressure discharge tube to generate glow discharge, which causes the gas molecules to release the laser, and the laser energy is amplified to form a pair The laser beam for material processing, the laser beam vaporizes the surface of the processed body to achieve the purpose of carving.

UV laser marking machine

UV Laser Marking Machine uses a 355nm UV laser to strike a laser beam on the surface of various substances, and directly break the molecular chain of the substance through a short-wavelength laser, thereby engraving patterns, trademarks and texts, etc. Permanently marked marking equipment.
