Dosing systems for any kind of application

The dosing systems of Movacolor are developed and produced for any kind of application in the plastics industry. The main purpose of dosing systems for injection molding and extrusion applications is that the desired capacity can be set and the output remains as close as possible to this set value.

Movacolor dosing systems for any kind of application

A wide range of high quality dosing systems

Movacolor develops and produces a wide range dosing products for injection molding and extrusion, continuous in-line blenders included. These high precision dosing systems meet the need for high volume, quality and reliability in the dosing of all kinds of materials like masterbatch, powders, regrind and liquids for producers in the plastics industry all over the world.

Dosing systems with different technologies

The Movacolor dosing system product range distinguishes three main dosing technologies, the gravimetric, optometric and volumetric dosing technology. Movacolor is world leading in the technology of gravimetric and optometric dosing systems. Together with the MCSmart software you can get full control over your production process and if needed adjust it exactly where needed.

Next to the gravimetric and optometric dosing systems, also the high quality robust volumetric dosing systems of Movacolor are unique in its kind. Through to the high precision dosing cylinder a smooth dosing output is guaranteed without any interruptions.

Gravimetric and volumetric feeders for injection molding and extrusion

Movacolor develops and produces accurate gravimetric feeders and volumetric feeders for injection molding and extrusion applications. All plastic parts produced by an injection molding machine and extruder need one standard: the highest quality. An accurate gravimetric or volumetric feeder is therefore an essential part of coloring main material by dosing colorants as masterbatch, regrind and liquids into the main material stream. The engineers of Movacolor are constantly working on innovative dosing solutions to reach the highest quality in injection molding possible.

The most accurate dosing technique for dosing masterbatch, powders and regrinds in injection molding and extrusion is based on the use of the dosing cylinder. All gravimetric and volumetric feeders of Movacolor are equipped with a unique Movacolor dosing cylinder and dose extremely accurate. The dosing cylinder releases the additive in a steady flow directly into the main material without any pulsations or interruptions.

Key features of dosing systems

Gravimetric dosing systems

  • Continuous loss-in-weight measuring, for a more accurate output
  • Automatic material calibration
  • Does not work well with extreme low dosages (< 0,02 g/s)
  • A bigger investment, but cost recovery on long-term

Optometric dosing systems

  • Works well with very small capacities; pellet by pellet dosing
  • Only capable for dust free material of equally shaped granules

Volumtric dosing systems

  • Constant feed and accurate dosing
  • Manual adjustment
  • Output does not change under fluctuating circumstances changes; like loss in weight
  • Volumetric units are a smaller investment
