Audited Supplier Industrial Barrel Mica/Ceramic/ Nozzle Band Heater For Extruder Injection Molding
1-Ceramic Band Heater:
Ceramic band heaters are made of helically wound nickel chrome resistance coil precisely stretched and strung through steatite ceramic cores forming a flexible heating mat.
It is then placed in flexible stainless steel housing with ceramic fibre insulation. These heaters are very flexible and can be fitted easily. Durable, ceramic band heaters provide excellent energy efficiency with their built-in ceramic fiber jackets.
Unlike mica band heaters, ceramic heaters transfer heat through conduction and radiation and do not require tightening around the cylinder. Flexible, these heaters come in a wide variety of terminal styles, and with different clamping mechanisms, holes and cutouts.
Features:
1. Nickel-chrome wire in a outer wall composed of interlocking ceramic tiles
2. Inside medium-high temperature heaters up to 1200° F
3. Outside shell temperature: 350° - 450° F
4. Built-in ceramic fiber insulating mat
5. Stainless steel jacket
6. Minimum diameter: 60mm
7. Minimum width: 25.4MM
8. Thickness: 12mm
9. Broad range of terminal types and thicknesses of ceramic fiber insulation mats
