K2016, hall 15, booth B27/C24/C27/D24 Schematics of an injection moulding machine with a loop-back control under the influence of disturbances exceeded. The deviations measured at this stage are, however, not yet strong enough to identify the object as defective. The operator now has the opportunity to intervene in the produc- tion and correct the deviation before it gets stronger, resulting in bad parts. This is a double economic advantage for the customer: they save material by preventing waste as well as work- ing hours by its fast and objective inspection on the production line. www.intravis.de
