MT-A710 hot-cut type knife-holder adopts the air pressure design to control the downstroke, equip with a special heating blade that can process the slitting and melt simultaneously. The knife-holder is provided with small dimension, rapid rise/ cool down temperature and highly stable slitting quality. Unlike conventional heating methods, MT-A710 can be heated to the required temperature within 1 minute, savings in warm-up time significantly. It can also be cooling down to the room temperature within a few minutes, to prevent the operator from inadvertently touching the blade to get hurt. MT-A710 can also be operated with MT-A710C the temperature controller optionally. MT-A710C using the SSR method by PID controller, can control the working temperature much precisely, ensure the consistency of the slitting quality.
