Conductor preheater with integrated temperature measurement and control

Preheater 6000 TC continuously adjusts the power of the preheating with the result that the wire always has the nominal temperature, inde- pendently of conductor material, the dimensions of the conductor and the line speed. No further setting is necessary. LED displays directly on the Preheater 6000 TC show the measured temperature at different perspectives. The integrated, non-contact temp- erature control makes the Preheater 6000 TC unique. It is available for temperatures up to 250°C, for a product diameter of 0.32 to 4.5mm (0.08 to 16mm²) and for a line speed of up to 2,500m/min. Three device models are available for the power range of 10, 20 and 30 kW. A power calculator at www.sikora.net/ powercalc helps choose the optimal device. The Sikora temperature measuring system is also available as the stand-alone system Wire-Temp 6000.

Designed to minimise installation costs and time, the equipment is easily interfaced with a PLC thanks to pre-programmed controls. A control screen with integrated HMI displays the operations in progress and offers self-diagnostic capabilities: machine status, event history, backup files and maintenance messages are accessible in real time. Benefiting from a wealth of application experience with major car and automotive parts manufacturers, in precision mechanics, aeronautics, medical and other leading-edge sectors, Technifor delivers end-to-end equipment meeting its customers’ expectations.

MANUFACTURERS cables, specifically automotive and data cables, require a reliable conductor preheating, to ensure an optimum adhesion of the insulation on the wire, and a controlled foaming. With the Preheater 6000 TC (temperature controlled) Sikora has an advanced solution for precise conductor preheating, the basis for high-quality cable production and repeatable control of the production. In only a few applications, it may be sufficient to control the output power of a conductor preheating device only depending on the conductor size and type, the line speed and the required temperature. However, there are numerous influences on the accuracy of the conductor temperature, such as the ambient temperature, the initial temperature of the conductor and particularly the development of the temperature of the wire guiding short-circuit wheel within the first ten to 20 minutes after starting the production or after an interruption of the production. At a time when machine-to-machine communication is proliferating in the industry, Technifor has risen to the challenge with a new range of laser marking machines that are making their mark as a true model of integration – Laser Solution F-Series. The new electronics offer communication tools natively, allowing continuous and instantaneous inter- action with the various workstations integrated into the chain of production. Dedicated and generic inputs/outputs, TCP/IP Ethernet, Profinet, RS232, USB, the configuration, control and data recording options are cutting-edge and allow for remote control. The new connections eliminate the need for costly adapters and offer the prospect of a single central server managing a factory’s entire fleet of lasers. Ultra-fast, the choice of high- performance electronic components of

The Preheater 6000 TC is positioned before the extruder and inductively heats the conductor to the desired nominal value. The integrated IR camera ensures a non-contact measurement of the wire temperature at the output of the preheating device. The controlling module of the ❍ Conductor preheater with integrated temperature measurement and control has resulted in marking equipment that is 50 per cent more time-efficient than the previous generation. Available in a range of powers from 10 to 50W, the Laser Solution F-Series permits the direct and permanent marking of a wide variety of parts and materials (plastics, metals, ceramics, etc). From surface marking to deep engraving, it executes 1D and 2D codes, guaranteeing faultless scanning. These new laser machines offer a real technical advantage to integrators and manufacturers who need to install marking stations on production lines. Highly compact, the marking head is adapted to industrial constraints: small spaces, extreme conditions of temperature and vibration, it is robust and protected from dust or other splashes (class IP54). The solution can be integrated with no necessity for
