Volumetric feeder for injection molding and extrusion

Volumetric feeder for injection molding and extrusion

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.

Does a volumetric feeder always need to be calibrated manually?

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:

• Accurate feeding through dosing cylinder
• Stepper motor speed starting from 0.1 up to 200 rpm
• Manual adjustment
• Capacity 0.07-180 kg/h, measured with normal granular masterbatch 0.8 kg/dm³
• Automatic recipes storage function
• The menu-guided control has a graphic LCD display with backlight
• A warning and alarm output and an integrated hopper loader control are also part of the MC30
• This volumetric feeder is suitable for both injection molding and extrusion

Volumetric feeding with a high precision dosing cylinder

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.

When is a volumetric feeder the best option? 

Volumetric feeding perfectly fits the needs of plastic processing companies who wish:

• Reduction of (investment) costs
• Accurate dosing when calibrated regularly by hand – MC18, MC12, MC18 Micro, MC12 Micro
• Accurate volumetric feeding offering extra control and monitoring – MC30
• An output of 0.01 – 1.0 gr/s– MC18 Micro, MC12 Micro
• An output of 0.07 to 180 kg/h– MC30, MC18, MC12
• An accurate dosing unit in terms of sustainability
• Higher efficiency
• More stability in the production process
