KEM – direct coloring unit

With thousands of installations, the KOCH KEM direct dyeing device has proven many times over that it is the simplest and best-value solution for dyeing plastic material with masterbatch.
The dosing quantity can be variably adjusted. During impulse-dependent dosing (injection moulding), the dyeing process is carried out fully automatically with volumetric chamber dosing for the entire time granulate is supplied to the screw, with the main component being added via a free feed device. Therefore, when the product is changed, there is no mixed material in the machine.

Changes to the dosing values can be noted immediately on the product. Dye or material changes can be carried out quickly, cleanly and without tools.

The controller component is integrated in the machine housing and offers a choice of two two programmes for injection moulding machines and two programmes for extruders. Furthermore, it is possible to store up to 20 different recipes.
