MPF Volumetric Feeder

The MPF powder feeder is designed to dose free-flowing to poorer flowing powders.

  • Hopper with integrated powder feeder paddle
  • Simple installation & easy feeder access
  • Removable stainless steel hopper for quick material changes

MPF Powder Feeder

Removable Stainless Steel Hopper

  • Hopper capacity restricted to 0.5 cubic foot (14 L) which is about 10 pounds (4.5 kg).
  • The restricted capacity design avoids compaction of powders and helps ensures consistent metering.

Spiral Dosing Auger

  • The powder feeder uses a spiral screw to assist with powder dosing.
  • Choice of spiral screws and motors according to settings and throughputs.

Integrated Powder Paddle

  • Hopper features an integrated powder paddle that sweeps the bottom of the hopper every 2 turns of the spiral auger.
  • Keeps the flights of the auger consistently loader with powder to ensure accurate dosing.
  • Powder paddle driven by a v-belt for integrated operator safety.

5 Year Warranty

  • Backed with 5 Year Warranty.

MPF Feeder Operation

Simple Setup Procedure

  • Enter the percentage setting.
  • Then either the molding shot weight or extrusion throughput. 
  • The MPF Feeder automatically doses, metering color evenly into the process machine.

Easy Cleanout and Material Changes

  • Easy removal of hopper, auger and auger tube.
  • No tools required, no pellets cross contamination.
