Once connected, the CMG controller tracks the input signal from the host machine and allows the FlexCart to accurately meter the required color or additive for the process. The reservoir cassette is a key operating element of the FlexCart unit, allowing the user to quickly changeover colors in a matter of minutes. The packaging is designed to effectively contain and transport Avient liquid colors and additives.
