How to Replace the Ceramic Band Heater
Some customers asked: What is the replacement method of the ceramic band heater? Today we will introduce how to replace the ceramic band heater.
Replacement of ceramic band heater
1. After waiting for the mold to cool, remove the hot mold half from the mold.
2. Remove the positioning ring (the other function of the positioning ring is to fix the thermal nozzle).
3. Install the lifting hole with M3 screws, remove the thermal nozzle, and pay attention that the band heater cannot be squeezed.
4. Remove the snap ring and the heat shield of the band heater.
5. Hold the head of the thermal nozzle, turn clockwise and turn and pull the heating ring to gradually separate from the thermal nozzle
6. When installing the new wire, the band heater should be as close as possible to the main body of the hot nozzle, and the front end of the band heater should reach the main body of the ring groove at the front end of the inner core of the hot nozzle.
7. Rotate the band heater clockwise to move it toward the head of the hot nozzle to ensure that the heating wire completely reaches the front end of the hot nozzle. Pay attention to the distribution of the band heater on the hot nozzle at both ends and sparsely in the middle.
8. Install the heat shield of the band heater. If the heat shield is tight, check whether theband heater is installed in place.
9. Install the circlip and detect the standard resistance value of the band heater and calculate the power (standard power is engraved on the band heater), and detect the resistance value of the thermocouple (0 or less resistance).
