Feng Rui laser engraving laser marking technology is one of the largest laser machining applications. Laser marking is high tobacco and alcohol use laser marking machine energy density laser illumination of a workpiece, so that the surface material vaporization or color changes in chemical reaction, thus leaving a permanent mark marking method. Laser marking can play a variety of characters, symbols and patterns and so on, the character size can be orders of magnitude from millimeters to microns, which have special significance for security products. Fine laser beam focused by as tools, surface material can be removed by point, its nature that the labeling process is non-contact processing, no mechanical compression or mechanical stress, it will not damage to be processed goods; the After the laser focus size is small, the heat affected zone, fine processing, so you can complete some conventional methods can not achieve the process. Feng Rui laser fiber lasers used in laser marking advantages: good beam quality, close to the diffraction limit. TEM00 fundamental transverse mode output, M2 close to 1, the beam divergence angle of 0.24mrad; high pulse repetition frequency, output power stability, single-pulse energy fluctuations of less than 1%, enabling high speed laser marking, spot size can be precisely controlled, depth, shape; high efficiency, plug efficiency up to 20% conversion efficiency up to 70%; environmental adaptability, continuous work under high-vibration, high-humidity environment; no water cooled, small size, high efficiency, high reliability, long maintenance-free use of cost savings.
