6.19 Removing and Installing Nozzle Tip Insulators (If Equipped)
Nozzle tip insulators protect the gate details and nozzle tips from damage and prevent resin leaks.
The following procedures describe how to remove and install nozzle tip insulators.
6.19.1 Removing the Nozzle Tip Insulators
To remove the nozzle tip insulators, do the following:
WARNING!
Burn hazard – risk of serious injury. To avoid serious burns, wear personal protective
equipment consisting of a heat-resistant coat, heat-resistant gloves, and a full face shield
over safety glasses. Use adequate ventilation for fumes.
1. Separate the cavity plate from the hot runner. Refer to Section 6.14 for more information.
NOTE:
Some nozzle tip insulators may remain in the gate detail in the cavity plate.
2. Lock out and tag the machine. For machine lockout and tag procedures refer to the machine
documentation.
IMPORTANT!
Due to geometric variations between the gate details and the witness marks left in the nozzle tip
insulators by the nozzle tips, Husky does not recommend reusing nozzle tip insulators. Previously
used nozzle tip insulators should always be replaced with new nozzle tip insulators. If reuse is
absolutely necessary (i.e. unscheduled maintenance with no spares on hand), order new nozzle
tip insulators and replace as soon as possible. Contact your nearest Husky Regional Service and
Sales Oce or www.husky.co.
IMPORTANT!
Nozzle tip insulators form to the dimensions of the nozzle tip and gate detail when compressed.
Before removing a nozzle tip, make sure to record the nozzle tip location and the orientation of
the nozzle tip insulator. This will help avoid resin leakage if the nozzle tip insulators are reused.
3. If nozzle tips must be reused, record the position and orientation of each nozzle tip insulator.
