Inline color measurement of plastic injection-moulded parts
The SKZ (Süddeutsche Kunststoff-Zentrum) has developed and tested an empirically determined correlation of the color between warm and cold pieces as part of a study. This enables any color deviations to be recognized at an early stage thus avoiding waste. The cooling curves pre-determined and stored in the software allow the color values determined during the de-moulding process to be converted into a reference temperature (24°C). The color is now automatically checked earlier in the process, which optimizes productivity and output. The described method saves time and guarantees 100% color quality control.
