Figure 3.7 – Recipe edit screen 2
A major difference between manual operation and automatic recipe control is that
recipes give the user the ability to utilise a Progressive Catalysation Ratio (PCR).
This is where the user can specify a desired start and end percentage for the catalyst
ratio. During an automatic injection, the machine will linearly vary the percentage of
catalyst, based upon the volume of resin injected.
Figure 3.8 – Recipe edit screen 3 (head pressure control)
Figure 3.8 shows the appearance of the display when head pressure control is selected,
while Figure 3.9 illustrates the mould pressure set up screen.
Select the required control mode and then set all of the variables for the injection,
including the required volume of resin to inject. Press the right arrow button to
advance to the next screen.
The penultimate screen, illustrated in Figure 3.10, is concerned with temperature
compensation. This feature allows the user to configure the machine to automatically
adjust the start catalyst percentage and the end catalyst percentage, based upon the
ambient temperature in the workshop.
