Safety instructions
Risk of burns
•
Hot surfaces
Many components of the hot runner systems get very hot and may cause severe skin burns when
being touched.
•
Hot material (plastic melt)
Never touch material leaking from the nozzle/the mould/the hot runner or the material inlet. Even
material that seems to be cooled down already may still be hot inside the core and cause burns.
Safety measures
•
Please make sure you wear your personal protective equipment (PPE) when working near or on a
hot runner system. Pay special attention to warnings indicating hot surfaces. All components have
to be cooled down to ambient temperature before you start working. Exceptions to these rules are
explicitly mentioned.
Risk of electric shocks
•
Danger to life by electric shock.
Touching live surfaces may result in severe or even lethal injuries.
•
Always keep water away from live components and the hot runner. There is a risk of short circuits!
Safety measures
•
Electrical systems have to be disconnected from the mains and secured against being switched on
again before any work is carried out. Only authorised electricians are allowed to carry out any work
on electrical systems.
•
All components have to be connected to a suitable power source according to the wiring diagrams
and under consideration of the applicable local regulations. Injection moulding machine and hot run-
ner systems have to be grounded.
Risk of physical injuries by suspended/heavy loads
•
Only trained staff is authorised to operate lifting devices and forklift trucks. Proceed slowly and with
care. Prevent the uncontrolled swinging of the loads (e. g. the manifold).
Safety measures
•
Lifting devices and forklift trucks have to be designed to bear the weight and the size of the hot run-
ner system/manifold. Make sure to use the marked lifting points.
Risk of physical injuries by pressurised connecting lines
(e.g. air, hydraulics, water)
•
All supply lines for the medium supply of the hot runner and/or the hot runner system or the hot half
have to be long enough to prevent any stress when the mould halves part. They must not be affected
by moving parts of the mould or of the machine. Prevent the hoses from rubbing over the edges of
the mould as they may be damaged because this might cause a spontaneous leakage of pressurised
process media (pressurised air, hydraulic oil, water).
Safety measures
•
Make sure you have depressurised all supply lines before carrying out any work.
Only skilled personnel is allowed to carry out work on the supply lines. Please wear your personal
protective equipment (PPE).
Risk of physical injuries by sharp edges and corners
•
Sharp edges and corners pose a risk of injury, possibly resulting in skin abrasions and cut injuries.
Safety measures
•
Make sure you wear protective gloves when working near sharp edges and corners.
Proceed with care.
•
Make sure the system is clean and free of burrs.
