2. General in ormation
2.1 Safety
The equipment is only esigne an may only be use for the osing of ry a itives.
Any use that is not in conformity with the instructions is consi ere improper an as such
frees the manufacturer from any liability regar ing amage to things an /or persons.
Before switching on the unit for the first time, ensure that the mains power voltage
applie is between 80 an 260Vac.
Always switch off the Movacolor control cabinet an isconnect the mains power plug from
electrical power before performing maintenance.
Ensure that all parts are securely fixe to the extru er or injection mol ing machine.
Dangerous voltages are present insi e the control cabinet for up to 2 minutes after it has
been switche off.
2.2 Certification
The Movacolor osing unit is esigne an pro uce in conformity with the following European
regulations:
• stan ar s for machinery (health, safety, environment)
• EMC (electromagnetic compatibility)
• VEM (safety electric material)
• 98/37/EC, Annex 1(See the eclaration of conformity, Appen ix E)
2.3 Operating environmental conditions
• The unit must be protecte against weather con itions
• Operating temperature -20 to +70 egr. C.
• Protection class: IP-50

3.2 Weighing frame
The black part is the weighing frame.
Do not touch this weighing rame (and dosing unit) while dosing.
It will have influence on the osing.
Do not touch the safety bolts un er the weighing platform. These are for overloa protection.
There must be some space between e safety bolts an the frame.
3.3 Motor and dosing system
There are mainly two osing systems, the osing cylin er an the fee screw.
(for more information see chapter 5)

The serial number of the motor can be foun on the
backsi e of the motor.
Motor axle:
The motor shaft is equippe with one flat si e which
fits exact in shaft of the osing cylin er.
To connect the osing cylin er just put it on the
motor axle while turning it to fin the flat si e, than
press the osing cylin er completely backwar s.

4. Metering principle
The Dosing Cylin er® of Movacolor combine with a very precise a justable stepper motor
ensures that the a itive output is accurate an regular. The neckpiece (a mixing chamber) is
esigne to blen the main material an the a itive homogeneously. Movacolor has on stock a
large range of machine neckpieces that usually make a prefect fit to the injection mol ing machine
or extru er. The most common mounting of the neckpiece is between the pro uction machine an
the hopper. In the figure below a cut through of the NST40 neckpiece can be seen.
Standard neckpiece
During operation, the virgin material runs from
the machine hopper through the neckpiece
into the machine. Insi e the neckpiece the
Virgin material flow is ivi e into two
streams
by the cover plate. In the space below the
cover plate, the rotating cylin er is osing
a itive.
A itive is a e irectly into the center of
the virgin material flow, just before it enters
the pro uction machine. This is a great
a vantage over metering evices that use
batch pre-mixing because pre-mixing can
actually cause material separation.
Separation of materials results in an irregular
a itive flow into the pro uction machine.

All Movacolor osing units are stan ar equippe with the stepper motor 2A (LT), in case of using
the fee screw A30 the stepper motor 4,5A (HT) will be supplie . Also a screw A20 can be
connecte to the HT motor.
 Do not select the HT motor if LT motor is connecte . This will amage the motor.
If LT motor is selecte an HT motor is connecte there will be less motor torque an this can
influence the osing.
The controller of the osing unit makes a istinction between two groups of materials, normal
granules an micro granules. To etermine the kin of material in your application use the
escription below.
* For other sizes contact Movacolor.
The actual capacity of the osing system epen s 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 an pow er material has to be
free flowing, non-static an not sticky.
