Section 9 - System Startup
and Shutdown
WARNING
Ensure that you have fully read “Section 3 - Safety”” before starting up or
shutting down your FUSION SERIES
®
G2 system.
9.1 Pre-Startup
WARNING
Take appropriate safety precautions by assuming the system is pressurized
and hot at all times.
CAUTION
Water must be turned on for Hot Runner actuation before turning on
temperature controls. Actuator water temperature cannot exceed 29.4°C
(85 °F).
When running thermally sensitive materials, use a thermally stable material
as recommended by the material supplier for the initial startup.
After the FUSION SERIES
®
G2 system is installed in the molding machine,
make sure to bleed all the air out of the hydraulic lines, if applicable. Failure
to do so could result in high gate vestige.
Check that the system is heated to processing temperature before actuating
the valve pins. Failure to do so could cause damage to the valve pins.
The maximum operating temperature for Hot Runner systems is 400°C
(750°F).
CAUTION
1. Install the mold into the molding machine.
NOTE
Ensure that the machine nozzle opening is the same size, or is not more
than 1.0 mm (0.040 in.) smaller, than the back plate bore.
2. Connect all water lines and test to ensure there are no leaks and that the
required flow is achieved in all water circuits.
3. Connect all hydraulic / pneumatic lines, if applicable.
4. Connect all electrical components and monitor to ensure that all zones
are receiving heat and all thermocouples are reacting appropriately.
5. If applicable, test the valve pin actuation, but only if the FUSION SERIES
®
G2 system is at processing temperature. See CAUTION above.
