Preheating with temperature control

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.

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.

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. 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. Sikora AG – Germany Website : www.sikora.net Various communication interfaces

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
