Gravimetric Feeders




The Plasticolor 2000 GR

Is a rugged gravimetric auger feeder. The unit accurately feeds free flowing color and additives at the throat of extrusion,
blow molding and injection molding machines.The system incorporates a special algorithm that filters out vibrations
and movement from mold clamping making it suitable for use on injection molding machines.Plasticolor 2000 GR
utilizes a stepper motor providing high resolution of speed control from 0.3 rpm to 225 rpm. Isolated 10/100 Ethernet
makes possible the retrieval of production information. An integrated venturi loader is included

Features:
Easy Setup
  • Injection molding – Just enter the shot size and % of additive you want to add. Start the feeder and it will
    automatically adjust itself to the machine cycle.
  • Extrusion – Enter the max output of your production machine and the % of additive you want to add.
    The feeder will automatically follow your extruderspeed and adjust accordingly.
and
  • Rigid mechanical structure
  • Automatic material parameter tuning
  • Easy and fast material changes
  • 0.1g weighing resolution
  • Loss-in-weight
  • Materials Accounting
  • Special algorithms for Injection Molding
  • Integrated loading system for pellets and micro granules
  • Stepper motor operated (1600 steps per revolution)
  • Screw speed control 1:600 – 0.3-225rpm
  • Typical feed rate 0.16 – 66 Lbs/Hour
  • Easy upgrade of older Plasticolor units.

Gravibelt

Is a gravimetric belt feeder. The unit accurately feeds free flowing color and additives at the throat of extrusion, blow molding
and injection molding machines. The system incorporates a special algorithm that filters out vibrations and movement from
mold clamping making it suitable for use on injection molding machines. The Gravibelt offers a wide dynamic feed range under
one setup. With a feed rate from 1 oz to 80 lbs/hr for pellets and 0.5 oz to 30 lbs/hr for micro pellets. Isolated 10/100 Ethernet
makes possible the retrieval of production information. An integrated venturi loader is included with the system.

Features:
Easy Setup
  • Just enter the shot size and the % of additive you want to add. Start the feeder and it will automatically adjust itself to the machine cycle.Injection molding –
  • Enter the max output of your production machine and the % of additive you want to add. The feeder will automatically follow your extruder speed and adjust accordingly.
  • Extrusion Easiest startup in the industry! Just let the built-in hopper loader fill the hopper, start the feeder and you are producing within minutes.

LW™ Series Continuous

Continuous type loss in weight gravimetric dosing unit for dosing and line control.
Designed for extruder machines, extruder output supervision, gram per meter control
and precise layer control in a multi-layer extruder line.

Benefits
  • Extruder output supervision
  • Gram per Meter control
  •  Precise layer control in a multi-layer extruder line
  • Fast control during ramping using Cotex Control
  • No need for tuning or setup when replacing materials
Features
  • Stainless Steel construction
  • Semi-automatic calibration
  • Standard Omron PLC control
  • Single off center load-cell per channel
  • Additives feeding using screw and/or belt feeders
  • Belt feeders have the unique ability of 1:1500 feeding range
Specifications
