C.S.O. uses laser fibre marker for printing of all metallic and most of the plastic materials. The biggest advantages of the laser fibres is undoubtedly the long service life of the key laser component and low power consumption while retaining maximum marking efficiency. Further advantages of this type of laser are the installation dimensions and air cooling. The fibre lasers are characterised mainly by high quality and precision of the laser jet with a diameter of up to 0.06 mm. Thanks to the high quality of the fibre lasers, lower performances suffice for quality printing of the materials. Most often, the customers demand the description of the part number, sometimes also the manufacturing batch, etc.
