The compact system for clean dosing of liquid colors in plastic injection molding
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.
If you have any specific question about the dosing system, please contact our colorDoS® expert Mr. Olaf Lang at firstname.lastname@example.org.
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
- Compact dosing system
easy installation directly above the feed area of the injection molding machine
- Gentle precision dosing
high color fidelity with minimum color application by micro annular gear pump
- Clean handling
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
- Intuitively operated display control
different operator levels, remaining time display until container change, alarm manager, color formulation management, cleaning mode, communication with injection molding machine, etc.

This overview includes only manufacturers of liquid colors with which we have gained our own experience. It is not a full manufacturer overview.
Manufacturer for liquid colors
ROWASOL has been part of the ROWA Group from Pinneberg since 2004 and is a specialist for high-quality liquid colors and additive concentrates for efficient plastics processing. Customer-specific solutions are developed and produced at the Karstädt site in the Federal State of Brandenburg. The implementation at the customer site is supported step by step by the technical customer service. The product portfolio is completed by the reusable container ROWASOL COLOR CUBE for a resource-saving and clean handling of the products.
Habich Farben, a family business since 1785, produces liquid colors for industrial coloring at its site in Reinhardshagen. The variety and flexibility of HABISOL liquid colors are due to the preparation form and are therefore universally applicable. The team of colorists and production engineers offers you complete advice on all aspects of liquid colors and processing and supports you in complying with legal regulations such as BfR and FDA. HABISOL liquid colors are also available for use in bio-based and compostable plastics, as effect colors and as mono-colors for mixing by yourself.
