Dosing with a volumetric feeder means adding masterbatch, powder, regrind or liquid additives by volume to a plastics production process. A volumetric feeder needs to be calibrated manually as the volume can change due to external factors. Volumetric feeding is used in both injection molding and extrusion.
Our most sold volumetric feeders for injection molding and extrusion applications:
In the injection molding industry the volumetric feeder MC12 Economy of Movacolor is well sold. This is the cheapest volumetric feeder of Movacolor and also very suitable for extrusion applications. For the extrusion industry Movacolor offers the volumetric feeder MC18 Synchronic, which adjusts automatically to the extruder speed. The robust MC12 Economy and MC18 synchronic are relatively low on investment, immediately give high savings and are easy to operate with a control panel.
Both of these volumetric feeders also feature a MCMicro version which is used for the smallest injection molding machines and capable of dosing masterbatch and powder with a capacity varying from 0.01 – 1.0 gr/s. Plastic producers who opt for an automatic hopper loader to fill the hopper automatically with masterbatch, powder or regrind chose the MC18.
Is it always necessary to calibrate a volumetric feeder by hand? No it isn’t. The volumetric feeder MC30 Auto Calibrate of Movacolor is equipped with an automatic material calibration function. Other features of the MC30 Auto Calibrate volumetric feeder are:
All our volumetric feeders are equipped with a high precision unique Movacolor dosing cylinder. The Movacolor dosing cylinder doses the additive in a steady flow directly into the main material without any interruptions or pulsations. Dosing with a Movacolor dosing cylinder ensures far more accurate dosing than other dosing techniques using a screw for example.
Volumetric feeding perfectly fits the needs of plastic processing companies who wish:
