Ultrasonic metal welding machine is specially used for the welding of metal workpieces, which has the advantages of good conductivity. Ultrasonic plastic welding machine is specially used for the welding of plastic workpieces, which has the advantage of high speed. These two welding machines are ultrasonic welding machines, which are used in all walks of life according to the classification of welding materials. Today we mainly talk about the application of ultrasonic metal welding machine in the printing industry and its working principle.

When the ultrasonic metal welding machine starts welding, it destroys the oxide layer on the metal surface through tangential vibration, which makes the metal surface rough, the friction increases sharply, and the rough surface continues to expand. Its tangential vibration effect will be better than that of ultrasonic plastic welding machine. The crystal clusters of metal matrix materials are sheared and extruded, and the local temperature rises sharply. In the intermediate stage of ultrasonic metal welding machine, the softened Crystal Cluster surrounds the damaged oxide layer particles and mixes them into clusters. At this time, the welding metal can be plastically deformed by increasing the pressure, which is generally thinner. It should be noted that when the ultrasonic welding machine presses the welding materials, it should pay attention to the strength. Excessive force may cause the materials to be welded through. In the later stage of ultrasonic metal welding machine, when the vibration stops, the temperature drops sharply, the crystal cluster can be cooled quickly, and the impurities with low melting point can be refined and fused with the crystal cluster.

The above is the principle of ultrasonic metal welding machine used in the printing industry, cutting and welding through the vibration generated by the welding machine. It can solve the disadvantage that the ultrasonic plastic welding machine can not weld metal, and fuse the metal workpieces quickly and highly. Ultrasonic welding machine provides exquisite welding services for all walks of life because of its advantages of ultrasonic technology. By expounding the principle of ultrasonic metal welding machine in the printing industry, we have a clear understanding of ultrasonic technology. We hope that the future technology can be continuously improved and better serve the printing industry.
