It is better to
fill out the part at slower speeds in-order to let
any compressed air escape, and to get the best
surface finish on the part.3
• Using all of the previous settings, record the
Transfer Pressure, Fill Time, and Injection
speed
• Reduce the injection velocity by 10% and
record the same values

• Keep reducing the injection velocity until a
fill time of 10-15 seconds is reached
• Calculate the Relative Viscosity for each of
the Injection Speeds using the equation
above (Transfer Pressure * Fill Time)
• Calculate the Relative Shear Rate for each of
the injection speeds using the equation
(1/Fill Time)
• Plot the points on a graph and find the
optimum velocity
• The optimum velocity will be where the
curve starts to level out
In figure 48 above, the optimum velocity is where
the plotted line crosses the black trend line;
therefore the optimum velocity would be about
1.00 in/sec.
