The compact system for clean dosing of liquid colors in plastic injection molding

The product launch of the new dosing system for liquid colors is planned for October 2020. Find out more about the system design, the product advantages and the functionality of the control system right now.

If you have any specific question about the dosing system, please contact our colorDoS® expert Mr. Olaf Lang at olaf.lang@hnp-mikrosysteme.de.

 

colorDoS® is a compact dosing system for liquid colors in plastic injection molding. The dosing system is mounted above the injection molding machine directly in the feed area of the conveying screw. colorDoS® can be easily integrated into existing machines.

Short fluid connections between the container and the pump module, equipped with dripless quick-release couplings, ensure a quick and clean color change as well as the dosing of smallest color quantities. The filling level of the liquid color is monitored by a load cell integrated in the container holder.

The intuitively operated display control synchronizes the precise, repeatable dosing with the injection molding machine. Cleaning mode, color formulation management, remaining time display, alarm manager etc. complete the extensive functionality of the control system.

We are happy to advise you on your colorDoS® system solution, support the on-site implementation and train your staff in the use of the dosing system for liquid colors.

Advantages at a glance

  • Clean handling
    thanks to dripless quick-release couplings, short fluid connections, dosing nozzle design for smallest color quantities without color transfer in the feeding area
  • Fast color change
    low void volume allows fast rinsing of the pump module and thereby a fast color change

Functions of the colorDoS control

  • Different operator levels
    operator, administrator, service
  • Remaining time display
    with adjustable advance warning time until container change
  • Color code management
    storage of up to 30 color code formulations
  • Cleaning mode
    allows fast color change
  • Alarm manager
    displays warnings (e.g. low filling level) or failures and can stop the injection molding machine to avoid waste.

Applications

  • Plastic injection molding
