2-1 Introduction
This manual is to be used with the Digital Dosing Disc additive feeder. The feeder precisely
meters and controls the addition of color concentrates, master batches, additives, regrind, and
other materials to plastic processing systems. The Digital Dosing feeder can meter pellets,
micro pellets, prill, powder and granular material of various sizes, when equipped with the
appropriate dosing module. It can be used on extruders, and blow molding and injection
molding machines. Single or Dual Station feeders are the most popular, but three and four
component models are also available. See Figures 1 and 2. This manual covers the
installation and operation of all of these feeders.
