Exact dosing is very important during 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.
Movacolor develops and manufactures gravimetric and volumetric feeders for any extrusion application. The manufacturer only needs one high precision dosing system for 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 extrusion runs 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 extrusion process. Precisely this type of dosing system is what Movacolor has to offer: highly accurate gravimetric and volumetric feeders for extrusion.
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.
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 (watch the video below to see for yourself). All our volumetric, optometric and gravimetric dosing units for extrusion are quick and easy to clean.
The gravimetric, optometric and volumetric dosing units of Movacolor designed for extrusion are easy to operate. They are constructed in such a way that any user working in the plastics industry can operate them, with initial start-up of your extruder taking no time at all.
The modular design means that manufacturers using the extrusion machine can use a dosing unit that has been created to client specification, perfectly suited to a particular production type in any extrusion application. Setting up or making the dosing unit ready for operation is extremely simple.
