Gravimetric Accuracy

Return on Investment 

  • MGF software and hardware reduce waste of colorants and additives drastically.
  • Maguire Gravimetric Feeders eliminate manual handling and mixing and reduce operation costs.
  • Save typically 30% on masterbatch costs compared to manual or volumetric dosing.

Twin Load Cells

  • Lightweight aluminum hopper mounted on 2 load cells which measure the weight of the hopper and the material ONLY.
  • Continuously monitors the loss-in-weight as material is dosed and automatically adjusts flow rate.
  • Measuring only the hopper and masterbatch allows for finer resolution load cells versus weighing complete feeder assembly and motor. This achieves maximum accuracy and control.

Accuracy of ± 0.2%

  • Automatic, continuous updates to flow rate calibration during production process.
  • Stepper motor provides high resolution control to dose masterbatch accurately to ± 0.2%.
  • Choice of dosing screws combined with software control provide industry-leading accuracy.

PRIME Calibration (patented)

  • Fast-track calibration on startup. Fully automatic and ready within seconds.
  • Primes screw and barrel with material, ready to start production.
  • Quicker startups and reduced scrap rates.

100% Injection Coloring (patent pending)

  • For critical additives, masterbatches and tints.
  • All material in injection molding machine barrel is now colored and gaps are eliminated. No scrap.
  • Ideal for fast cycling / small shot weight applications.

What Makes the MGF Unique?
