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 the retrofitting at existing lines.
The system comes with all common
interfaces such Ethernet, Profibus,
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 conductor 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 made by
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 buses
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.
