Thickfilm heaters for hot-runner
nozzles
BlueFlowGünther's new BlueFlow ®
technology incorporates several
advantages as compared to
conventional heating methods: the
heating elements are not only
considerably smaller in diameter,
they also allow a substantially better
temperature distribution and
accordingly, a quicker thermal
response.
Nozzle type:
- 5SEF/DEF
- SMF/DMF/NMF

Further outstanding features are
their high electric strength and
resistance to moisture. All in all,
these four features are important
steps taken towards a more spacesaving,
precise and energy-efficient
hot runner design and, therefore, a
more effective injection molding
process.

Heater are pressed into a brass
body. The heater is fixed in place by
the mechanical structure of the
carrier body. The homogeneous
brass body ensures optimal heat
transfer from the heater to the
material tube, showing a highly
reproducible temperature pattern.
