6.1 Safety instructions
WARNING!
PPE
Unwanted sudden escape of melt caused by thermal degradation or gas release
of plastic material
Unwanted escape of melt caused by different thermal expansion of materials
due to temperature differences
Heavy burns to body and extremities.
•
Before operation the system must be heated through for at least 3-5 min.
•
Only process materials which are approved for use with the system.
•
The safety devices of the injection moulding machine must be active and working
HAZARD!
PPE
Insufficient protective conductor connection to the injection moulding machine
Risk of deadly electric shock or severe injuries due to live components.
The operator must ensure that during startup of hot runner single tips or hot runner
systems all electrical system components have been wired to to the protective con-
ductor system of the injection moulding machine or are protected by equivalent safety
measures before applying electric voltage. When applying electric voltage to systems
or to system components beyond specified normal operation, sufficient ground earth
connection or equivalent safety measures must be ensured for each component.
Raised injection pressure
The system is designed for an injection pressure of 2000 bar. When the cavity pres-
sure is too high (e.g. by overpacking a cavity without limiting the injection pressure)
components of the hot runner system may break and hot plastic melt can escape.
Injection moulding processes must only be carried out with maximum pressures of
2000 bar. If the process requires higher pressures a written permission of EWIKON
Heißkanalsysteme GmbH is needed.
