GraviColor dosing unit

A dosing unit can easily add an additive or masterbatch to the process. A dosing unit is also called a colouring unit to colour a product using masterbatch.

The GraviColor is a gravimetric dosing unit that works very accurately and reliably. With a special transport system, weighing bunker, stepper motor and smart software, a masterbatch or additive is added to the process very accurately.

Features and Benefits:

Very high accuracy
Great saving of masterbatch and additives
Ease of use
Quick and easy to set up
Self-learning and optimization program
Suitable for both injection molding machines and extruders
Significant time savings when changing materials

GraviColor dosing unit

The GraviColor has its weighing bunker in the housing, so that environmental factors such as hoses, cables or people cannot negatively affect the weighing.

The neck of the unit is placed on the injection molding machine or extruder and has a special stainless steel static mixer that ensures that the masterbatch or additive is added in the middle of the material flow.

By means of a screw/cylinder the masterbatch/additive is dosed very precisely. There are different versions available depending on the desired capacity.

The GraviColor has smart software that monitors the set and actual added amount of masterbatch/additive every cycle. Based on the difference that occurs, the dosing amount is improved so that this system is self-learning and optimizing. For example, if the operator adjusts the plasticizing time, the GraviColor will automatically adjust to this.

Features and Benefits:

Very high accuracy
Color touchscreen
Easy operation and calibration (multilingual)
Self-learning and optimizing program
Maintenance-friendly design
Easy cleaning when changing masterbatch
Integrated Venturi suction system
Very accurate and reliable
Solid, compact and durable design
Universal connection flange
Great saving of masterbatch and additives
Robust and solid design
Weighing bunker integrated into the housing, therefore no negative weighing influences
