Changing recipes with other additives or regrind may change color values without permission. For this reason, a color measurement is required immediately after the point of addition. Every color deviation can be measured directly and a correction made possible. This reduces rejects and complaints due to incorrect color information.
For the installation, a measuring point is defined in the interior of the extruder chamber, a Buss tooth is drilled in the kneader or a connecting ring in the planetary roller extruder and a color sensor with fiber optic cable is implemented behind bulletproof glass.
