Gravimetric and volumetric feeders for injection molding

Gravimetric and volumetric feeders for injection molding

Movacolor develops and markets accurate gravimetric and volumetric feeders. All plastic parts produced by an injection molding machine 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. 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 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.

The stepper motor ensures maximum control without stoppages or pulses. The dosing method based on a dosing cylinder ensures therefore far more accurate dosing than other dosing techniques based on blending, using a screw, disc or feeding belt especially in modern injection molding machines with extreme short production cycles.
