Installation of HPS III valve gate hot runner systems
1. Check the clearance
∆S
between the surface of the
upper pressure pad (pos. 1.4) and the surface of the
nozzle retainer frame plate (pos. 53) and compare it to
the value given in the drawing provided by EWIKON.
2. Install the intermediate plate (pos. 54), the insulating
plate (pos. 50) and the clamping plate (pos. 51).
3.
Install the locating ring (pos. 6) and fix it with socket
head screws (pos. 6.1, ISO 4762 - 12.9). Tighten with
matching torque. See chapter
„9. Tightening torques“.

1. Unscrew the valve pin retainer (pos. 11.1) from the drive
unit (pos. 11) by using a wrench.
2. Insert the valve pin (pos. 11.2) carefully into the valve pin
retainer from behind.
3. Screw the valve pin retainer with valve pin to the drive
unit again and tighten it with matching torque.
See chapter „9.6 Tightening torques for valve pin retainer
for electric drive units“.

All clearances must be checked in cold condition!
In case of deviatons the clearances must be adjusted in an appro-
priate way (e.g. by machining the nozzle retainer frame plate or the
pressure pads of the manifold).
Attention:
The adjustment must not have influence on the dimension
X of the nozzle!
Checking of clearance when using nozzles for front installation
When nozzles for front installation are installed the contour pla-
te (pos. 56) must be installed before the clearance Δ
S is checked.
Otherwise the measurement is falsified.
NOTE!
Connected power supply during installation
Risk of deadly electric shock or severe injuries due to live compo-
nents.
• The hot runner system and the mould have to be disconnected
from the voltage source during installation.
HAZARD!
Sharp edges and heavy components
• Cut injuries to body and extremities, mainly to the hands.
•
Crushing of fingers or hand.
Control of live components before installation
The electrical equipment of the hot runner system should be
checked, especially those areas which will no longer be accessible
after installation. Physical injuries such as an electric shock can be
prevented that way.
Please check
• if cables are kinked or squeezed.
• if cable insulations are undamaged.
WARNING!
