MT-A710 hot-cut type knife-holder adopts the air pressure design to control the downstroke, equipped with a special heating blade that can process the slitting and melt simultaneously. The knife holder is provided with compact dimensions, rapid rising/cooling temperature, and highly stable slitting quality. Unlike conventional heating methods, MT-A710 can be heated to the required temperature within 1 minute, significantly saving warm-up time. It can also be cooled down to 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 more precisely, ensuring the consistency of the slitting quality.
