Injection mode :
Before an injection is started, ensure all external connections to the mold etc. are
correctly made. Also ensure that resin and catalyst lines are correctly primed and that
the required levels of materials are available. Ensure the level of fluid in the flush tank is
sufficient to clean the machine after the injection. Injection mode cannot be entered
while recirculating or flushing.
NOTE: When the system is initially primed with resin and catalyst, ensure the
machine is run in inject mode and resin is collected in a suitable container from
the mixing head and that air is purged etc. Once this has been done, ensure the
resin is correctly catalyzed by performing cup tests prior to using the machine to
inject a mold.
Prior to and during operation in injection mode, use the pump pressure regulator and
gauge to suitably adjust the air pressure supply to the pump and control the pump
speed.
Set the MPG set-pressure to the required pressure. Once the injection has begun, the
pump will stop running when the fluid pressure at the injection head exceeds this
setting. When the injection line pressure reduces below the MPG set-pressure, the
machine will continue to inject.
Adjust the predetermining counter to set the number of required pump strokes for the
injection. See figure 5 for an overview of the predetermining stroke counter. To change
the preset count, press and hold the white button with arrow decal while pressing one of
the black buttons under the preset count corresponding with the digit to be modified.
NOTE: The machine cannot be started in inject mode, if a previous injection has
stopped automatically when the shot count has been reached and the stroke
count has not been reset. Press the reset button on the predetermining counter to
reset the count and allow the machine to be started. See figure 5
Press the inject button to start the machine in inject mode. The machine cannot be
started in inject mode if it is operating in recirculation or flush modes. The injection head
will open, the Pro gun/TAS signal will pressurize and the pump will run. To stop the
machine and leave inject mode, press the stop button. If the predetermining counter
reaches the user set shot count, the machine will stop automatically.
If a PPVS sensor is being used the pump will stop when the mould pressure reaches
set-point. When the mould pressure drops to an acceptable level, the pump will run
once again.
