Computer control system, touch-screen and simple operation, fast and accurate. Hydraulic control system absorbs domestic and foreign advanced technology using energy saving low noise devices. Dual fuel tanks, four posts with precise self-balancing to ensure the consistance of each cutting depth. Manual hydraulic cutting operation, press the button once to finish one cycle without any disadvantage of imtermittent cutting many time. Differential cutting design, die quickly descends, when it moves closing to cut mould then changes to automatic slow cutting, which can eliminate the error between upper and lower layer. Eco-friendly materials such as PET, PP, OPS, EPE, ABS will not have rough edges or uncutting edges. It can avoid some waste powder sticking on the food boxes. Ad Hoc cooled rotary encoder systems and devices make the positioning of knife mold more accurate and stable.
