Premiere of the Wire-Temp 6000

With temperature measurement, precision with Sikora’s Wire-Temp 6000 reaches levels never seen before at the heating of a conductor with a conductor preheating. The name says it all: The Wire-Temp 6000 continuously measures and controls contact-free the temperature of the conductor at the output of the Preheater 6000 with a permanent precise actual value of the conductor temperature for all conductor cross-sections, at all line speeds. Thus, the Wire-Temp 6000 raises the benchmark for conductor preheaters to a completely new level. During production there are numerous influences on the accuracy of the conductor temperature. Examples are the ambient temperature, the initial temperature of the conductor and, in particular, the development of the temperature of the so called ‘short-circuit wheel’ within the first 10 to 20 minutes after starting the production or after an interruption of the production. The new Wire-Temp 6000 considers these factors and determines the conductor temperature indep- endently from cross-section, material and surface structure of the conductor. The Wire-Temp 6000 is optionally the new

integrated in the proven preheater system Preheater 6000 and can easily be retrofitted in existing devices. In addition, it is available as an independent system without the Preheater 6000.

Die drool elimination Excess of material at the output of a die during an extrusion process, also called die drool, can significantly reduce the production speed of a cable. A clear comprehension of the phenomenon for any kind of polymer is not yet available. Nevertheless there is some help to reduce the impact of such default: PTFE-coating. Erocarb has recently introduced a new 3-layer coating for extrusion tools with great success. In order to save the concentricity, the mounting surfaces remain blanked hardened steel. The only surfaces in contact with the polymer will be coated. As die drool appears on inside and outside surface of the extrudate, Erocarb recommends the coating of both tip and die. Erocarb coating is applicable on hardened steel but not on carbide. Erocarb – Switzerland Website : www.erocarb.ch
