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 Transfer (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 • 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.

It will highlight the progression from basic inks to the most cutting-edge products available today, such as bio-derived inks with 40-59% bio-content, energy-efficient inks that cure at lower temperatures (as low as 250°F compared to the traditional 320°F), and non-PVC inks.

Union Ink low-cure inks feature a wide curing profile, allowing cure temperatures between 270°F and 320°F (132°C and 160°C)

The ink is ready to use and is formulated to prevent drying on the screen, even on 320-mesh count.
