Advanced Single Component Gravimetric Feeder

ColorSave 1000 is a highly accurate and cost-effective single component masterbatch & additive gravimetric feeder for injection molding, extrusion and blow molding machines, that offers significant cost-savings and production efficiency advantages for plastics manufacturers.

ColorSave 1000 is the original single component gravimetric feeder for injection molding machines, and is still the only gravimetric feeder available with an internal weighing hopper – ensuring unmatched resistance to mechanical shocks and vibrations, while providing the most accurate weighing and dosing.

The innovative design and proprietary algorithms found in the ColorSave 1000 ensure homogenous feeding, regardless of material density changes or other dynamic parameters.

Benefits of a Double Hopper

ColorSave 1000’s external hopper acts as a protective shell for the internal hopper; preventing operator contact, air drafts and other factors from interfering with the weighing accuracy of the load cell. The mechanical separation of the weighing chamber from the screw feeder, motor and additive loader provides precision and accuracy of additive feeding that is unmatched in the industry.

  • Highly sensitive load cells
  • Accurate and precise feeding
  • Significant cost savings

Product Features

  • ColorSave 1000 provides the industry’s highest precision of additive feeding.
  • ColorSave 1000’s automatic calibration enables you to consistently feed at the desired set point.
  • ColorSave 1000’s user-friendly design allows you to quickly clean and sterilize components between jobs.

Significant Savings Compared to Volumetric Feeders & Batch Blenders

ColorSave 1000 brings significant cost reductions when compared to standard volumetric feeders or batch blenders. Save up to 50% of your masterbatch (MB) costs by making the switch to the gravimetric ColorSave 1000.

Alternative TechnologiesMB Savings with ColorSave 1000
