Exact dosing is very important during plastic extrusion. Parts that are manufactured using the extruder must meet the highest quality requirements. For dying the main material through dosing of an additive, it is recommended to choose a dosing system that is suited to the extrusion process.

Gravimetric and volumetric feeders for plastic extrusion

Movacolor develops and markets gravimetric and volumetric feeders for any plastic extrusion application. The manufacturer only needs one high precision dosing system for plastic extrusion which is also easy to operate for everyone working in the production area of a plastic producer. Our gravimetric and volumetric dosing systems for plastic extrusion run quietly.

A dosing system that uses dyes and other expensive additives sparingly and so can save on costs, as well as contributing to a continuous plastic extrusion process. Precisely this type of dosing system is what Movacolor has to offer: highly accurate gravimetric and volumetric feeders for plastic extrusion. Gravimetric feeders are also known as loss-in-weight-feeders.

Plastic Extrusion with a high precision dosing system

The highest precision dosing technologies for the dosing of additives in extrusion applications, such as masterbatch, catalysts, cleaning materials, powders and regrind, are based on the use of a dosing cylinder. All our gravimetric and volumetric dosing units are equipped with a unique Movacolor dosing cylinder.

The Movacolor dosing cylinder doses with the highest level of precision when used for extrusion. It releases the additive in a steady flow directly into the main material without any pulsations or interruptions. The stepper motor ensures maximum control over your extrusion application without stoppages or pulses. Dosing with a Movacolor dosing cylinder ensures therefore far more accurate dosing than other dosing techniques based on blending, using a screw, disc or feeding belt.

Plastic extrusion with easy-to-operate modular dosing systems

In the plastics industry, every minute that an extrusion machine is not operational leads to unnecessary costs. Movacolor designs its dosing units for extrusion in such a way that dyes can be changed in less than a minute. All our volumetric, optometric and gravimetric dosing units for plastic extrusion are quick and easy to clean.
