Jaye Heater's Extruder Mica Band Heater is designed for heating the barrels, dies, and other cylindrical components of plastic extrusion equipment. The heater uses mica insulation and a resistance heating element to provide efficient and uniform heat transfer around the extruder barrel.
Mica band heaters are widely used in plastic extruders because they offer good electrical insulation, stable heating performance, and a compact structure. The heater can be customized in diameter, width, voltage, wattage, terminal type, and mounting configuration to match different extruder designs.

Plastic extrusion requires stable barrel temperatures to keep the material in the correct processing condition. An improperly heated barrel can cause uneven melting, unstable extrusion, and inconsistent product quality.
An Extruder Mica Band Heater provides several advantages for this type of application:

Mica band heaters are commonly installed around the barrels of plastic extruders to heat and maintain the processing temperature of thermoplastic materials.
They can be used for different extrusion processes, including:
Some extrusion dies and cylindrical processing sections also require external heating. A customized mica band heater can be manufactured to fit the required diameter and heating area.
The heater helps maintain a stable temperature around the processing section, which is important when consistent material flow and forming conditions are required.
Mica band heaters can also be used on other plastic processing equipment where a cylindrical metal surface needs controlled external heating.
Typical applications include:
