With the Preheater 6000 TC (TC – temperature controlled),
Sikora offers a solution for a precise conductor preheating, the
basis for high-quality cable production.
The Preheater 6000 TC is positioned before the extruder and
preheats the wire by means of inductive
heating up to 250°C. A controlling module
controls the power of the Preheater 6000 TC
depending on the conductor material, the
conductor dimension, the line speed and the
desired temperature.
The measurement of the wire temperature
inside the Preheater is unique as it is
measured by a non-contact infrared camera.
With the approach of the direct integration
of a wire temperature measurement in
the Preheater and the feedback to its
power control, it is assured that the wire
temperature is always at the desired level.
The Preheater is available for a product
diameter of 0.32 to 2.8mm (0.08 to 6mm²) and
applicable for new lines as well as retrofitting
existing lines. The system comes with all
common interfaces such Ethernet, Profibus and
Profinet IO as well as analogue ports.
Initially developed for Sikora’s Preheater,
the Wire-Temp 6000 is now also available
as stand-alone version and for retrofitting after existing
preheaters. The Wire-Temp 6000 determines the cond-
uctor temperature independently from the cross-section, the
material, the line speed and the surface structure of the
conductor.
A big advantage over conventional systems
is that the temperature measurement is
madeby means of a non-contact thermal
image sensor in an infrared camera, which
detects the conductor reliably and provides
accurate measurements with no need for
calibration. The Wire-Temp 6000 is available
for product sizes from 0.1 to 10mm and from
0.15 to 100mm.
Various
communication
interfaces
are
available for the transmission of the
measuring values to a Sikora processor
system, the line control or a laptop. The
universal interface module for connections
to RS485, RS232, Profibus DP or industrial
field busses such as CANopen, Ethernet/
IP, DeviceNet and Profinet IO fulfils every
demand. The interface module and all
connection plugs are fully sealed for
protection against water, dirt and mechanical
damage.
