Section 1: Introduction

This User’s Manual is intended for use with the Digital Dosing Additive Feeder. The feeder precisely meters and controls the addition of master batches, chemical additives, and regrinds to primary plastics. The Digital Dosing unit can meter both powder and granular material of various sizes. It can be used on both extrusion and injection molding machines. Depending on the application and throughput, two models are available: 1 Station Digital Dosing Unit or 2 Station Digital Dosing Unit. See Figures 1 and 2. This manual covers the operation of both units.
