3.5. Manual Injection Setup
When the user wishes to perform a manually controlled injection, they must firstly
press the MANUAL INJECTION button on the main menu screen. This will
navigate to the manual injection setup screen, which can be seen in Figure 3.1. This
screen gives the operator the ability to select what is connected to the mixing head,
manually flush the machine and select between either a mould pressure or head
pressure controlled injection modes.
Initially the user should configure what is connected to the system. Pressing a sprue
button will toggle it between disabled and enabled. When a sprue is enabled, the
operator also has the option to enable or disable the limit switch checking function.
Once any sprue is enabled, the machine will provide the open/close signal to control
the action of any connected sprues.
This system allows a great deal of flexibility for the user and configures how the
machine will flush in manual mode. Connection options range from a simple dispense
from the head into a container with no signal to open a sprue (all sprues disabled),
through to a fully sequenced and monitored configuration featuring four Turbo
Autosprues (TASs) with position monitoring and flush sequencing. See section 3.3 to
review the connection options.
