Colour change systems

Our colour change systems are suitable for simple or complex applications as peripherals for extruders and injection moulding machines. They are available as standard for two to eight dosing units, or as special designs with more than eight dosing units.

Operating principle

With our colour change systems it is possible to switch from one colour to the other within seconds without interruption. The control can shut down one production unit while simultaneously starting another. Each dosing unit is equipped with a pneumatic neckpiece slide. These open and close automatically, which prevents material from trickling out. Secure closure of the dosing unit that is not involved in the recipe means that it can be prepared for the next production run.

Practical benefits

  • Immediate switching of production
  • Easy handling and operation
  • Low quantity of pre-mixed material
  • Reduced set-up costs
  • Avoidance of production waste and rejects
  • Scalability via merging of multiple units

Controls

Our colour change systems achieve maximum accuracy thanks to precise control via our PDC-series modular controls or PPM control systems.
