4. Metering principle
The Dispensing cylinder®of the Conair TrueFeed is combined with a very precise adjustable stepper motor to
ensure that the additive output is accurate and consistent. The throat adapter (mixing chamber) is designed to
blend the main material and the additive homogeneously. Conair supplies a large range of machine throat
adaptors to fit injection molding machines. The most common mounting of the throat adaptor is between the
production machine and the machine hopper. In the figure below, a cross-section of the NST40 throat adaptor
can be seen.
Standard throat adaptor
During operation, the virgin material runs from the
machine hopper through the throat adaptor into the
machine. Inside the throat adaptor the virgin material
flow is divided into two streams by the cover plate. In
the space below the cover plate, the rotating cylinder
feeds additive material.
Additive material is added directly into the center of
the virgin material flow, just before it enters the
production machine. This is a great advantage over
metering devices that use batch pre-mixing that can
cause material separation. Separation of materials
results in an irregular additive flow into the
production machine.

6 Dual Feed TrueFeed Manual

All Conair TrueFeed feeders are equipped with a 2A (LT) stepper motor as standard. However, if you are using
an A30 feed auger, a 4.5A (HT) stepper motor will be supplied. An A20 auger can also be connected to the
4.5A (HT) motor.
LDo not select the HT setting in the control if a LT motor is connected. This will damage the motor.
If the LT motor is selected and a HT motor is connected there will be less motor torque, which can
influence the feeding.
The controller of the feeder makes a distinction between two groups of materials, normal granules and micro
granules. To determine the kind of material in your application use the description below.
* For other sizes contact a Conair representative.
The actual capacity of the feeding 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.

6. Installation
6.1 Transport
To protect the Conair Dual TrueFeed gravimetric feeder against damage during transport, the unit is packaged
in a cardboard box filled with polyurethane foam. Delivery terms are FOB Franklin, PA. The buyer is
responsible for the transport. Conair cannot be held liable for any damage that might occur during transport.
6.2 Receipt
Check the unit thoroughly upon receipt. Pass any remarks to the local agent or Conair representative within
eight working days upon receipt of goods.
6.3 Mechanical Installation
Most mechanical parts are pre-assembled, making installation quick and simple.
1. When installing a main material hopper (not included with feeder purchase) on top of the throat adaptor,
the 6 x 6 inch top flange of the NST40 throat adaptor will have 5 x 5 inch pre-drilled mounting holes.
2. -Install the throat adaptor directly on top of the entrance of the production machine.
-Install the throat adaptor in a 90-degree angle to the machine barrel. This will optimize the feeding
accuracy in relation to the vibration of the production machine.
-Make sure that the complete unit is mounted
horizontally leveland is secure.
-Assure proper grounding to control cabinet,
throat adaptor and feeder.
3. Remove the transport
protection pin (at the bottom
of the loadcell frame) before
placing the hopper
assembly. This is just a pin
on a flexible chain, do not
dismount the stainless steel
plate!
4. Connect the hopper assembly to the throat adaptor
by turning the thumb knob clockwise. Make sure that
the thumb knob is tightened firmly.
5. Mount the controller in a vibration-free area and away
from high temperatures.
Install the throat adapter in a 90-degree angle to the
machine barrel. As shown in the picture.

6.4 Changing from Dispensing cylinder to Feed screw
In relation to the maximum capacity of the dispensing cylinder, it might be necessary to change from the
selected dispensing cylinder to a feed screw. The feed screw system consists of a rotating auger in a
non-rotating tube. (See the detailed instructions listed below.)
To install the feed auger:
1. Detach the motor quick release clamps and take out the motor from the hopper.
2. Dismount the throat adaptor connection flange (1) by removing 4 socket-head screws.
3. For use with a dispensing cylinder the throat adaptor connection flange (1) is equipped with a ball bearing
(5). When using an auger screw system, the ball bearing must be removed. The metal ring (2) that is fixed
on the feed screw tube fits directly on the throat adaptor connection flange.
4. Dismount the dispensing cylinder (3) and mount the auger screw (4) with the M5 bolt.
5. Replace the motor and auger by closing the motor quick release clamps.
For cleaning, the motor and auger can easily be removed.

LInput mode is not visible in RPM Production Mode. (Timer is used automatically)
Input (start) signal
The Dual TrueFeed needs an input signal from the production machine in order to operate.
Two different input signals can be used to control the Dual TrueFeed.
1. A potential free relay contact.
Use the white and brown wire for the potential free contact.
2. A relay signal up to 30 Volt DC.
In case of a powered relay signal, connect the white wire to +24 VDC and the yellow wire to
the side. To detect a start signal, the TrueFeed needs a minimum voltage of 18 VDC.
Configuration: Input filter
The “Input filter” setting is only visible when “Relay” is selected as the Input mode.
In the Relay Input mode the length of the feeding time is measured automatically by the duration of the
incoming input signal. The Input filter calculates the average feeding time of the set number of shots (3-32)
The calculated average time is used as steady feeding time. The default Input filter setting is 3.
LDuring production, if a production setting was changed or if the “Stop/Start” button was pressed, the feeding time will
reset automatically.
