3.7 Hot Runner Safety Hazards
WARNING
• The equipment supplied is subjected to high injection pressures and
high temperatures.
• Ensure that extreme caution is observed in the operation and
maintenance of the Hot Runner system and the injection molding
machines.
• Do not operate the equipment with unconfined long hair, loose clothing
or jewelry, including name badges, neckties, etc. These may get caught
by the moving belt mechanism and can cause death or serious injury.
• Never disable or bypass a safety device.
• All operators should wear personal protective equipment, such as face
shields, and use heat resistant gloves when working around the feed
throat, purging the machine or cleaning the gates of the mold.
• Check frequently for possible oil or water leaks. Stop the machine and
make repairs.
• Do not look directly into the feed throat of a hopper. Unexpected release
of resin may cause serious burns. Use a mirror. Failure to do so may
cause serious injury.
• Remove purgings from the machine immediately. Never directly handle
plastic purgings or drool until they have completely cooled. Purgings
may appear solid but may still be hot and cause serious injury.
• Some plastics develop gases that may be dangerous to personal
health. Follow the plastics supplier’s recommendations. Review their
material safety data sheet. Ensure the molding area is well ventilated.
• Never touch or inspect the timing belt when power is on and motor and
controller are connected. Unplug the controller before any maintenance.
• Always cover E-Drive belt area / molding machine drop out area / bench
top with a proper protective cover before any bench test or in-mold
testing.
• High voltage and amperage cables are connected to the controller
(220 VAC). There is also a high voltage cable connection between the
servo motor and controller.
• Always unplug the controller before performing any maintenance work.
•
Hoses fitted to the mold will contain high or low temperature fluids or air
under high pressure. The operator must shut down and lockout these
systems as well as relieving any pressure before performing any work
with these hoses.
• Never perform any work on the mold unless the hydraulic pump has
been stopped.
• High voltage and amperage cables are connected to the mold. Electric
power must be shut off prior to installing or removing any cables.
