4.1.2 MB/AD Feeding Modes
There are two alternative MB/AD feeding modes, depending on the wiring of the "sensor" cable to
the IMM (see section 3.3.2 Sensor Cable Wiring Options):
Alternative A (Standard): MB/AD is fed only during the dosing (backward motion of the IMM
screw) phase
Alternative B (Optional): MB/AD is fed mainly during the dosing (backward motion) phase;
however, a certain quantity of MB/AD will be fed during the injection (forward motion)
phase as well. This option enables better color dispersion.
Notes:
a)
Timing and time duration of each phase is identified by the ColorSave controller by the sensor
input (when the relevant dry contacts in the injection machine are in "closed" state).
b)
The initial feeding rate during the "dosing" phase is determined by the controller according to
the entered parameters (part weight and MB/AD percentage) and the measured dosing time.
c)
The feeding rate during the "injection" phase, if applied, is 2/3 of the feeding rate during the
"dosing" phase.
d)
Feeding during the "injection" phase, if applied, will be performed in all 4 operation modes.
e)
The start of the "constant time" in modes 1 and 3 is synchronized always with the start of the
"dosing" phase. The time of the "injection" phase remains the time of the injection molding
machine.
4.1.3. Speeds Displayed On Main Screen
Waiting phase
This screen shows Speed 0.0% when the operation is
not in dosing phase or injection phase.
Dosing phase
This screen shows the dosing speed as received from
the dosing signal.
Injection phase
This screen shows the injection speed as received
from the injection signal, if "injection" phase is
applied (see section 4.1.2 MB/AD Feeding Modes).
