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.
