What materials are laser marking machines suitable for?

The Laser marking machine uses laser beam to mark the surface of various materials with permanent mark. The marking effect is to expose the deep material through the evaporation of the surface material, thereby engraving exquisite patterns, trademarks and characters. The laser marking machine types mainly have CO2 laser marking machine, fiber laser marking machine and UV laser marking machine.

Different type of laser marking machine is used for different materials. Fiber laser marking machine uses fiber laser to output laser beam, the beam quality is good. Compared with other types of laser marking machine, they have longer life span and can be used for processing various metals and non-metallic materials, especially for marking high hardness, high melting point and brittle materials.

UV laser marking machine belongs to the series of laser marking machine, but it adopts 355nm UV laser, the machine uses three order intracavity doubling frequency technology. Compared with infrared laser, 355 UV laser focusing spot is very small, it can greatly reduce the mechanical deformation of the material and has little processing heat influence. Therefore, it is mainly used for ultra-fine marking and engraving, especially suitable for applications such as marking food, medical packaging materials, micropores, high-speed division of glass materials, and complex pattern cutting of silicon afers.

The Co2 laser marking machine is a laser galvanometer marking machine that uses CO2 gas as the working medium. CO2 laser uses CO2 gas as medium, CO2 and other auxiliary gases are charged into the discharge tube, and add high voltage to the electrode, the glow discharge is generated in the discharge tube, the gas emits a laser with a wavelength of 10.64um. The laser energy is amplified and vibrated, after the scan of galvanometer and the focus of F-Theta lens, under the control of the computer and the laser marking control card, it can mark the image, text, numbers and lines on the workpiece according to the user's requirements.

Co2 laser marking machines mainly mark non-metallic materials, such as leather, fabrics, wood, resin plastics, bamboo products and so on.

The laser marking machine developed and manufactured by Shenzhen Sun Laser Technology Co., Ltd. is maintenance-free. The laser does not require any maintenance, and does not need to adjust or clean the lens, has a long service life. The whole set of equipment has the advantages of simple operation, convenient design, easy operation and easy maintenance, which can shorten the process, reduce the occurrence of bad items and improve production efficiency.
