Volumetric dosing units are designed to automatically dispense additives,
such as dyes, into the base material, installed on the neck of the machine
through a connecting flange with a static mixer or a flow mixing mixer. Are
intended for work with the granulated, powder materials (dyes,
superconcentrates, additives, etc.) or crushed.
Can be installed on injection molding machines, extruders, blowing
Dosing is carried out by a screw element due to material intake by the
interturn space. Therefore, the dosing of the additive is carried out
volumetric and the accuracy of dosing depends not only on the parameters and
operating modes of the dispenser, but also on the size of the granules. The
approximate accuracy of dosing is 1-2% of the volume.
