DD Series Digital Dosing System offers precise additive feeding for almost any plastics machine, for injection molding, blow molding, or extrusion. The DD Series Dosing System uses a variable speed DC drive motor and dosing disc to precisely feed pellet or powder additives, at the set rate, into the throat of the processing machine. Precision design disc’s and closed loop control ensures high accuracy, dependability and repeatability.

Material changeover has never been easier. Just lift two quick disconnects and remove the additive station. With the optional spare station, changeover is immediate. The simple changeover design reduces downtime and safety risk. The DD2 dosing unit offers the ability to use dual additives at different rates.
