PROCESS CONTROL | INLINE MEASUREMENT


With ColorAdjust


Without ColorAdjust


Above: KraussMaffei’s ColorAdjust system can automatically monitor and correct even minor colour variations during compounding


back to the light PP compound (after approximate- ly 1,200s). Large fluctuations in L* were observed within the individual batches, as well as the batch changes (Figure 2, left). The small and large fluctuations in brightness


were automatically compensated for by the colour control system over the duration of the process to maintain a constant L* of 62 (Figure 2, right) by means of variable addition of colorant. To complete the proof of the automated control, a constant result was achieved in a further experiment on the colour value b*, also with


fluctuating starting material. SKZ and ColVisTec the concept of automated colour control with the use of inline colour meas- urement has been successfully implemented. At this point, the system is tailored to a single colour axis but the researchers says it will be possible to extend the present concept to three-dimensional colour control. This will require several feeder units and a further development of the software, the requirements for which are currently being deter- mined. The experimental data also indicates that in some circumstances it should be possible to reduce the complexity of the setup to only one measurement point. The project was supported by the Federal Ministry for Economic Affairs and Climate Action (BMWK), through the German Bundestag. Inter- ested companies are now invited to learn more about the possibilities of the new system within the framework of cost-neutral trials at SKZ.


Controlling colour The ColorAdjust system from KraussMaffei combines a colour measuring device with photo- spectrometer technology and machine control to
