Potential Hazards
Mechanical Hazards
Body Crushing
Hazard
End of motor moves back during hold or recovery. A hazard may exist
between the end of the injection unit motor assembly and a nearby solid
obstacle. Ensure proper guarding as part of integration.
During installation of the E-Multi injection unit onto a mold, a crushing
hazard exists between the adapter plate and the mounting surface of the
mold.
A crushing hazard exists between nozzle and mold melt inlet during
carriage forward motion.
Shearing Hazard
A possible shearing hazard exists between the edge of the injection guard
and the injection housing during injection.
Cutting Hazard
For horizontally-mounted machines with a high center line height, a
person's head could hit the end of the injection unit causing a cut. Ensure
proper guarding.
Entanglement Hazard
(Belt Drive)
A person could become entangled in the drive belt or screw of the injection
unit. Always keep guards in place.
Entanglement Hazard
The open feed port could present an entanglement hazard. Always keep
guards in place.
Molten Material
Splashing Hazard
High pressure molten plastic may spray from the nozzle. Always use
personal protective equipment (PPE).
High temperature molten plastic may spray from a blocked feed port.
Always use personal protective equipment (PPE).
Loss of Stability
Injection unit could fall over if improperly installed on stand.
Injection unit could fall over if transported on stand castors.
Injection unit could fall from top of mold if not properly secured.
Injection unit could fall over if stored vertically on the floor or a table
without adequate support.
Trip Hazard
Controller cables are a tripping hazard on the floor between the controller
and the press or E-Multi injection unit.
Stored Energy
There could be stored energy in compressed plastic which is not released
when the machine is powered off.
When installed vertically and powered off, there is stored energy in the
injection assembly which could move downwards.
Electrical Hazard
Contact of Persons
with High Voltage
Heaters, servo motors and electrical components in the controller could
come in contact with a person. Do not remove covers when energized.
