The maximum height should be about 2 .5 times the nominal wall thickness (2 .5W) . 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 Transfer Pressure (psi) Fill Time (sec) Injection Velocity (in/sec) Relative Shear Rate Relative Viscosity 1238 0 .20 8 .00 5 .00 247 .60 1125 0 .22 7 .00 4 .55 247 .50 1058 0 .25 6 .00 4 .00 264 .50 960 0 .35 5 .00 2 .86 336 .12 870 0 .45 4 .00 2 .22 391 .65 780 0 .58 3 .00 1 .72 452 .59 690 0 .85 2 .00 1 .18 586 .78 600 1 .35 1 .00 0 .74 810 .45 510 2 .50 0 .75 0 .40 1275 .83 420 5 .23 0 .50 0 .19 2198 .34 330 9 .56 0 .25 0 .10 3157 .99 240 15 .26 0 .10 0 .07 3667 .49 FIGURE 47 - Injection Speed 22 Gravi-Tech • 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 .
