Replacing Melting Plate and/or Sealing Ring
WARNING: Hot! Risk of burns. Wear heat-protective gloves.
1. Heat the platen until the material softens (approx. 70 ° C / 158 ° F,
depending on the material).
2. Place a clean, hard, heat-resistant resting surface (e.g. metal plate) on
the container and lower the platen onto the surface.
3. Release all of the fixing screws (1).
4. Raise the platen approx. 10 cm. The melting plate remains on the resting
surface.
5. Shut down the bulk melter.
6. Carefully extract the temperature sensor from the bore (4).
7. Replace the O-rings (3). Clean and grease the grooves. Refer to page
8-2, Processing Materials for the type of grease to be used.
The sealing ring (2) can now be replaced. Refer to page 8-2, Processing
Materials for the type of grease to be used.
8. Apply heat transfer compound (Refer to page 8-2, Processing Materials)
to the temperature sensor and insert it into the bore (4).
9. Screw the melting plate into place:
a. Grease the fixing screws and screw in loosely such that the platen
and melting plate have thermal contact
b. Wait until the platen and melting plate are at the same temperature
c. Tighten the fixing screws with 10 Nm.
NOTE: The next time the platen is cold (e.g. weekend, factory vacation)
tighten the fixing screws again with the stated torque.
