Thermocutter with Standard Handle

These hot knife Thermocutters feature an electrically (110 or 220VAC) heated blade designed for cutting all thermoplastics easily and effortlessly. Heats up instantly. Transformer steps voltage down to a safe level. Cuts through material up to 5 inches thick.

This hot knife Thermocutter is designed for continuous, industrial operation— including on-off batch production, use at a central work station or on-site.

The Zetz-24 can be set for on/off operation or continuous use with the flip of a switch.

The cutting handle is connected to the base unit by a 9½ foot long 3-line electrical cable. Two lines are for AC power. The on/off switch in the handle electronically actuates the controller in the base unit on the third line using very little power. This 3-line cable design decreases temperature buildup in the handle.

Blades are changed quickly and easily. Temperature of the blade is adjusted by the variable controller on the base unit. This ensures that the blade is evenly heated to the temperature suitable for the application.

For automatic operations requiring the cutting blade to be built in, there is a special robotic handle available at the same price.

Choose the blade to suit the purpose. These blades are designed so that heat is concentrated along the cutting edge in order to achieve the optimum cutting temperature. Prior to insertion in the material to be cut, the temperature of the blades will be between 100°C and 800°C, depending on the type of blade and the thermocutter used. The temperature to the blade cools down as it enters the material. The temperature depends on the thermal properties and heat conductivity of the material being cut and determines the cutting speed. The cutting edge is evenly heated because of the design of the blade's cutting flanges.

Blades with model numbers in green are only for use with the Zetz-24 and 25 Thermocutters.
