Keyboard features secure shell laser engraving machine, protecting free, is currently the most sophisticated skills gas lasers, the most widely used, cost-effective products Apple phone shell symbol laser engraving machine, attributed to the second generation of non-metallic laser marking machine. For non-metallic materials were only symbolic. Laser module life of up to 30,000 hours, the whole one-time investment, 5 years free protection, no supplies. Fiber laser marking machine strengths and defects produced in the selection of the laser fiber laser marking machine, good beam quality, high electro-optical conversion efficiency. Advantages: Very good beam quality, higher accuracy, no supplies. Defects: Quote relatively high semiconductors. Laser marking marking process because you do not touch the workpiece and better than traditional approaches to chemical corrosion and other mechanical stamping spark carved. Laser marking for data to be processed can be a useful addition to the needs of the absorption of the laser wavelength outside without any special needs, and the workpiece without loss undisturbed without distortion, but also because of the selection process design and computer-controlled flexible. Selection of laser marking high degree of automation and processing process did not pollute the environment.
