Printing Plate Lasers Marking Machine

This state-of-the-art fully automatic Laser Marking Machine is engineered specifically for the printing and plate-making industry, addressing a critical post-production need. Once the intricate plate-making process is complete, printing rollers must be accurately and permanently identified with relevant content information at both of their ends. This identification is not merely for inventory management but is crucial for press operators to swiftly and correctly select the designated roller during high-speed printing operations, thereby minimizing setup time and preventing costly errors on the press floor.

Designed with versatility in mind, this robust machine accommodates a wide range of standard roller specifications to suit diverse production environments. It seamlessly handles rollers with outer diameters ranging from 100 mm to 400 mm, lengths between 350 mm and 1700 mm, and a maximum weight capacity of 50 kilograms. This comprehensive size range effectively covers the vast majority of rollers used in high-volume ink printing applications, from commercial packaging to publication printing.

The key operational feature lies in the electric Z-axis movement mechanism. We employ an 800W servo motor paired with a gear reducer to support printing rollers weighing up to 50 kilograms and precisely drive them to target positions. This enables symmetrical and positionally accurate marking. These markings must meet exceptionally stringent requirements: under the harsh lighting conditions common in printing shops, they must provide sharp contrast against metal substrates for instant visual recognition. Additionally, some printing facilities incorporate QR codes for scanning with barcode readers during material receipt, enabling more digitalized and traceable quality management.

To meet these stringent requirements, the equipment is equipped with a high-performance 50W Raycus Mopa Fiber Laser. The advanced MOPA (Master Oscillator Power Amplifier) architecture enables precise control of pulse parameters, efficiently and reliably generating deep gray permanent marks with depths ranging from 0.1 to 0.3mm. This process delivers not only high contrast but also sufficient depth to withstand wear, solvent erosion, and friction in printing environments. Consequently, end users can easily and accurately locate, match, and verify the correct cylinder for each printing job, thereby optimizing workflows and enhancing overall operational efficiency.
