Precise temperature specification

Unique is the non-contact measurement of the conductor temperature inside the PREHEATER 6000 TC (Temperature Controlled) with its direct feedback to the power control, for a precise control of the wire preheating. The PREHEATER 6000 TC is positioned before the extruder and preheats the wire by means of conductive heating to 50 up to 150 °C (optional 250 °C). The heating frequency of 2,000 Hz with a maximum power of 35 kW ensures a perfect uniform conductor temperature.


Innovatice temperature measurement and control

Without the exact measurement and control of the conductor temperature, there are numerous influences regarding the achievable accuracy – the environmental temperature, the initial temperature of the conductor and especially the development of the temperature of the wire guiding shortcircuit wheel within the first 10 to 20 minutes after starting or interrupting the production.

The perfect solution is a continuous measurement of the conductor temperature at the output of the PREHEATER 6000 TC as well as the continuous control of the power and therefore an always precise actual value, for all conductor cross-sections, at all line speeds. The specification of the nominal conductor temperature is taken directly from the display of the device or the system control. Operating errors are as much eliminated as repeatable processes are ensured. The measured temperature is displayed on large LED displays on both sides of the device.
