The Techmire process
parameters and shot monitoring system (PPCS) permits the machine operator to set
specific values for over 25 critical production
parameters (e.g., temperatures, injection
speed, and fill time). Each process parameter
can be programmed with upper and lower control limits.
The shot monitoring portion
of the PPCS is an excellent diagnostic tool
for operators and process engineers. Graphs
of shot profiles can be reviewed in real
time on the machine controller or at a remote
station linked to the controller via a network.

In the event that an out of tolerance
condition is detected, the PPCS
can be programmed to take a number
of actions, such as setting off
an alarm, stopping the machine,
or directing the components produced
to a separate bin, for later inspection.
(The machine has a directional
palette for this purpose.) All
out-of-tolerance injections are
logged with their respective parameters
for subsequent analysis.
