The standard version of the automatic positioning scans an area of 30° wide and it lasts 30 seconds.
The Reverse version is indicated in cases where the reading surface is subject to non-modifiable external surface reflections, such as a skylight, which distort the read data. In this case, a reverse positioning is necessary, opposite to the standard: instead of reading the surface immediately outside the press, the reading will be carried out a little further on. The software that manages the automatic positioning takes into account the distance from the press outlet to carry out the calculations of the isothermal extrusion.
The wide range of versions available supports a different uses: the scan covers an area of 30 °, 50 ° or 90 ° in 6 or 30 seconds.
The scanner can be managed independently by the IES Isothermal Extrusion system, or managed separately automatically or manually with a dedicated kit.
A correct reading of the profile temperature is important for controlling the extrusion process. For dies already in use, when changing the die, the scanner automatically moves the sensor to the position saved during the last extrusion of that specific die, using the parameters saved in the recipes in the IES Isothermal Extrusion system.
With a new die, the scanner positions itself at 45 degrees and evaluates the temperature and emissivity read. If the signal does not fall within the reading parameters accepted by the system, or if for any reason the signal is interrupted, the scanner automatically starts the search for a new position satisfying the necessary requirements (temperature and emissivity). At the end of the extrusion the value of the position is saved, with all the other parameters, in the die recipe and made available for subsequent reuse of the die.
