1. Introduction
Thank you for purchasing a Movacolor metering device. This manual is addressed to operators
and qualified technicians taking care of the metering of dry additives to ensure correct use of the
Movacolor dosing unit.
IMPORTANT NOTE: THIS MANUAL MUST BE READ BEFORE INSTALLING THE DOSING
UNIT. KEEP THIS MANUAL IN A PLACE ACCESSIBLE TO ALL OPERATORS.
Symbols:
Important note
Attention; safety regulations for the operator
Terms:
Operator: A person charged to operate, adjust, maintain and clean the machine.
Qualified Technician: A specialized, suitable trained person authorized to execute the
installation, non-routine maintenance, or repairs requiring special
knowledge of the machine and how it operates.

2. General information
2.1 Safety
The equipment is only designed and may only be used, for the dosing of dry additives.
Any use that does not conform to the instructions is considered improper and as such
releases the manufacturer from any liability in regard to damage to things and/or persons.
Always switch off the Movacolor control cabinet and disconnect from electrical power
before performing maintenance.
Ensure that all parts are securely fixed to the extruder or injection molding machine.
Dangerous voltages are present inside the control cabinet for up to 2 minutes after it has
been switched off.
2.2 Certification
•The Movacolor dosing unit is designed and produced conform the following European
regulations:
•standards for machinery (health, safety, environment)
•EMC (electromagnetic compatibility)
•VEM (safety electric material)
•98/37/EC, Annex 1(See the declaration of conformity, Appendix C)
2.3 Operating environmental conditions
•The unit must be protected against weather conditions
•Operating temperature -20 to +70 degr. C.

3. Overview Dosing unit
3.1 MC-12 Components overview.
3.2 Motor and dosing system.
There are mainly two dosing systems, the dosing cylinder and the feed screw.
(for more information see chapter 5)

The serial number of the motor can be found on the
backside of the motor.
Motor axle:
The motor shaft is equipped with one flat side which
fits exact in shaft of the dosing cylinder.
To connect the dosing cylinder just put it on the
motor axle while turning it to find the flat side, than
press the dosing cylinder completely backwards.

3.3 Neckpiece
The NST40-Neckpiece is the standard neckpiece for the MC-12 . The window of the NST40
neckpiece can be dismounted for easy cleaning. Together with the window the insert is taken out.
Easy cleaning
Dismount only these 4 bolts. Take out the window in a 45°angle.

4. Metering principle
The Dosing Cylinder® of Movacolor combined with a very precise adjustable stepping motor
ensures that the additive output is accurate and regular. For every particular application Movacolor
provides different neckpieces but the most common mounting of the neckpiece is between the
production machine and the hopper. In the figure below a cut through of the NST40 neckpiece can
be seen.
During operation, the virgin material runs from the
machine hopper through the neckpiece (1) into the
machine. Inside the neckpiece the virgin material flow (4)
is divided into two streams by the cover plate(3). In the
space below the cover plate, the rotating cylinder (2) is
dosing additive.
Additive is added directly into the center of the virgin
material flow, just before it enters the production
machine (5). This is a great advantage over metering devices
that use batch pre-mixing because pre-mixing can
actually cause material separation. Separation of
materials results in an irregular additive flow into the
production machine.

5. Dosing systems / Capacities
Depending on the application a different dosing system might be needed.
Use the following table to determine roughly the best system for the application. For more detailed

To determine the kind of material in your application use the description below.
* For other sizes contact Movacolor.
The actual capacity of the dosing system depends on:
•The volume weight of the material (bulk density)
•The specific weight of the material (specific density)
•The granular shape of the material
•The granule size
•The surface structure of the material
Granular material can be normal or micro. The granular material and powder material has to be
free flowing, non-static and not sticky.
Normal Granules:
(NG)
Micro
/ Mini
Granules:
(MG)
The term Micro/Mini Granules also
includes free flowing powder.
