Notes
The pressure pad is used to support the nozzle/
manifold against the cavity plate. It is made of
titanium steel which guarantees excellent insulating
properties and minimal heat loss. The
standard pressure pad comes in 12 mm size.
To secure the measurement “K” required for
the heat expansion of the manifold the customer
has to grind the pressure pad to the required
dimension.
See “yellow page” chapter 4.

Notes

Metal O-ring
After thorough testing and analysing,
GÜNTHER Hot-Runner Engineering has
decided not to fit any metal O rings into nozzles,
connecting pieces, connecting nozzles and
hot-runner systems. This regulation does not
apply to the “NEST/ NEST1” single valve-gate
nozzles, for which a metal O ring is essential.
The frequency of damage due to incorrectly
fitted metal O rings outweighs their ability to
prevent overmouldings of hot-runner systems.
Please note that metal O rings can still be
fitted into nozzles and hot-runner systems if
the customer so wishes but the leakproofness
of the hot runner will not be
guaranteed in that case.

Insulating caps
Notes
Insulating caps of PEEK are used in applications with carbon fiber filled
polymers, as well as metal fiber and metal powder filled polymers. It is
recommended to use insulating caps when processing thermally sensitive
plastics, e.g. PVC, or in applications with frequent color change.
The caps are heat resistant up to 350 °C.
* When using an insulation cap 817.185 for nozzles type 5_MF and
5_TT2 a redesigned gate area is required.
