WARNING
DANGER
IMPORTANT SAFETY INFORMATION
A hot-runner system includes electrical elements and may contain molten
plastic at elevated temperature and pressure. To avoid injury, exercise
caution by reading these instructions before servicing or operating the
system.
These instructions must be passed on to the end user where they should
be read before using this product. Failure to do so can result in serious
injury or death.
Failure to comply can result in serious injury or death:
STORED ENERGY AND HIGH TEMPERATURE HAZARDS
This product maintains molten plastic at high pressure. Use caution when
operating and servicing the system.
Physical contact with molten plastic may result in severe burns. Proper
protective equipment, including eye protection, must be worn. This product
has heated surfaces. Use caution when operating and servicing the system
to avoid severe burns. Proper protective equipment should be worn.
Failure to comply will result in serious injury or death:
ELECTRICAL HAZARDS
Improper voltages or grounding can result in electrical shock. Use only
with proper voltage and a proper earth ground.
To avoid electrical shock, do not operate product when wet.
Do not operate this equipment with covers or panels removed.
To avoid electrical shock, turn off main power disconnect and lockout /
tag out before servicing this device. Do not connect temperature sensors to
electrical power. It will damage the product and it can cause fire, severe
injuries or even death.
If green ground wire present wire must be connected to the ground.
Do not rebend rigid leads. Rebending leads might result in damage to circuit.
Product might absorb moisture when cool. Use low Voltage or power to drive
out residual moisture before applying full power. Failure to do so may cause
damage to this product.

8. Machine the "B" diameter + 0.0005 -0.0000 directly
into the cavity carefully, as this is a seal-off dimension to
fit the nozzle's seat.
9. For best processing and lowest gate vestige, tip must be
0.000 to 0.005 into the cavity at processing temperature.
The smallest gate diameter will yield the best gate vestige.
Depending on part configuration and plastic being used,
the gate may have to be enlarged to achieve greater
flow. This increase in diameter may result ina larger gate
vestige.
10. Provide maximum water cooling in the nozzle plate and in
cavity insert around plate.
11. Route wires through wire channel in nozzle plate.
12. Provide a gate dimple on core/cavity opposite gate. This
will allow for best material flow.
13. Wait a minimum of 5 minutes after set point has been
achieved for sufficient heat to transfer into the tip before
molding.
6. Seal ring for nozzle body must be replaced each time nozzle
body and / or manifold are removed to ensure seal off.
7. Machine the 2.626 diameter + 0.001 -0.000 directly into the
nozzle plate, 0.250 minimum to 0.750 maximum deep, to fit
the nozzle's head.
RECOMMENDATIONS AND GUIDLINES
Nozzle (multiple-applications) body must be cleaned 1.
of any material in the seal off area and threaded areas
before reassembling.
2. Careful attention should be taken to the tip as damage
could occur if tip is dropped or strikes a rigid material.
Treat tip like a glass or ceramic material.
3. Do NOT lubricate or use anti-sieze compound on the threads.
4. Tip must be torqued into the nozzle using a torque wrench
at 33 5 ft-lbs. When reassembling. For protection of the tip
point, use a 17 mm deep well 6 point socket.
5. Careful attention should be taken to the heater and
thermocouple leads as damage could occur when working
on nozzle assembly.
