We offer ceramic band heaters for plastic injection moulding machines. They both have their specific uses and careful selection should be made to ensure long life and premature failure.
Ceramic band heaters are widely used in industrial applications for heating cylindrical surfaces.
-
Construction:
- A ceramic band heater consists of interlocking ceramic brick tiles with a spiral-wound nickel-chrome resistance coil.
- These durable heaters are assembled like a brick wall, with the heating core placed inside the ceramic tiles.
- The assembly is covered by a ceramic fiber insulating mat and a stainless-steel jacket.
-
Temperature Range:
- Ceramic band heaters can operate at temperatures up to 1200°F (650°C).
- They are commonly used in injection molding, blow molding, and extrusion processes.
-
Heating Mechanism:
- Ceramic band heaters transmit heat through both conduction and radiation.
- The element winding heats the ceramic blocks, which then radiate energy into the barrel and conduct energy by being in contact with the surface.
- Fit is not as critical as in other types of bands.
-
Advantages:
- Excellent dielectric strength at high temperatures and high voltages.
- Allows for smaller increments in heater widths (as small as 1/8").
- Reduces the chances of damaging internal coils during transit and handling.
- Easier installation onto cylindrical devices like barrels.
