Is fiber laser or UV laser better for laser marking machine?
UV laser has an unshakable position in the plastic marking industry
Ultraviolet laser has a small focus spot, low thermal influence and high speed
Today, let’s discuss together: Is it better to use optical fiber for laser marking machine or UV?
Fiber laser marking machine and ultraviolet laser marking machine are different types of laser processing equipment, and their core components, processing principles and application fields are quite different. Below, let's make a specific comparison:
The laser used in the fiber laser marking machine is a fiber laser with a wavelength of 1064nm; the laser used in the ultraviolet laser marking machine is an ultraviolet laser with a wavelength of 355nm. As we all know, the shorter the wavelength, the smaller the laser spot, the higher the accuracy, the smaller the heat-affected zone during processing, and the finer the processing effect. Therefore, UV laser processing is cold processing compared to fiber laser processing. This determines their application areas: fiber laser marking machines are mostly used for laser marking on various metal surfaces, and ultraviolet laser marking machines are mostly used for ultra-fine non-metal processing, such as packaging surface marking for cosmetics, medicines, and food. Mark.
Therefore, the guide for purchasing a laser marking machine is: when purchasing a laser marking machine, it is necessary to analyze the actual production situation in detail. Such as plastic, data cable, power adapter, UV laser marking machine with finer marking effect can be selected.
Finally, the editor recommends a high-efficiency ultraviolet laser that takes both speed and effect into consideration: RFH Expert Ⅱ 355nm ultraviolet laser. It is the standard configuration of current ultra-fine UV laser marking equipment.
RFH Expert Ⅱ 355nm UV laser pulse width <14ns@30K, beam quality M2<1.2, spot ellipticity>90%. Its power control system is independently developed by the RFH Ph.D. team, which can update the power control system functional modules in time, and improve the functional modules according to laser requirements, and technically ensure the stability of the system, so it can maintain the stability of the system under extreme conditions in industry and scientific research. Consistent and stable performance. At the same time, it has an internal cavity self-purification system, which makes the laser long life and stable operation. It has a unique Q-switching control technology to meet the control needs of various laser applications, which can help laser marking manufacturers improve their competitiveness and make efficient profits.
After 12 years of hard work, RFH has won high recognition and good reputation from users in all walks of life at home and abroad, and has established an excellent brand image in the nanosecond laser industry.
