Bi-coloration technology allows one twin screw extruder to manufacture products with two colors. The colors are clearly defined and each colored section may have a different texture to give the product a distinctive mouthfeel.
Bi-colored products are manufactured using our bi-coloration kit. This clip-on module can be included on new production lines or added to existing production lines as an upgrading solution to diversify your production.
How does bi-coloration technology work?
Inside a special barrel the product is separated into two independent flows: each flow contains a colour and may also contain a flavour. These two flows are combined at a level of specific die-plate, and distributed to the die-inserts. See the drawing below :
