The second generation of plastic gear transmission, because the plastic gear in the injection molding, shrinkage and other processes are difficult to accurately master, resulting in the accuracy of the gear itself is not high, in high-speed operation, the noise is large, because the plastic parts are brittle, poor toughness, easy to appear tooth breakage.

3rd generation metal sprockets: Silent operation, low energy consumption, efficient cutting, and convincing functionality thanks to the perfect coordination of the various components of the cutting system.

The fourth generation shredder transmission mechanism is metal gear transmission, and the metal gear overcomes the above defects, but due to the uncontrollable technology and maintenance of the installation accuracy of the metal mechanism, the lubrication conditions at the gear meshing, and the lubrication effect of long-term operation.

The fifth-generation diamond sealing movement adopts alloy steel material, quenching treatment of metal tools, and complete CNC machine tool processing technology to ensure the installation accuracy of the transmission part, so that the wear is reduced to a minimum, and the product quality stability and noise are reduced. Quality assurance: super strong all-steel all-metal gears, special steel roller cutters, high-quality and high-strength motors.

The sixth-generation high-tech multimedia series shredder has high technical content, can shred a large number of optical discs, floppy disks, tapes, videos, etc., and has a knob panel with a protective film to ensure the functions of forward, backward, stop, and stop when full of paper.

The eighth generation On the basis of meeting the multi-function and high performance, the shredding capacity, confidentiality level and service life of the shredder have been strengthened by leaps and bounds.
