Preheating with temperature control

the conductor 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 the demand. The interface module and all connection plugs are fully sealed for perfect protection against water, dirt and mechanical damage.

With the Preheater 6000 TC (Temperature Control), Sikora offers a solution for 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 200°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 non-contact infrared camera takes the temperature inside the Preheater. 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 its 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 on existing lines. The system comes with all common interfaces such as Ethernet, Profibus and Profinet as well as analogue ports. Initially developed for Sikora’s Preheater, the Wire-Temp 6000 is also now available as a standalone version and for retrofitting to 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

New brake for pay-offs and take-ups Magnetic Technologies offers a variety of brakes for pay-offs and take-ups. The brakes, totally adjustable, give extremely accurate tension control and come in numerous sizes to fit customers’ spools and reels. Torque is developed magnetically and will remain the same year after year. Torque ranges from 0.11" ounces to 220" pounds. Single to multi-spool pay-off stands are also available. Advantages include adjustability, portability, no electricity, and a minimum of floor space. Every brake or clutch is carefully engineered to give exceptional long life, for even the most demanding production standards. They are designed to be easily mounted and serviced or modified, should the need arise. The company has added current controlled electric hysteresis brakes to its product offerings. Available in sizes up to 220lb/inch, the brakes complement the extensive offering of permanent hysteresis and eddy current brakes and clutches.
