The document is a report on a study comparing flow length and pressure for injection molding using Roctool technology versus conventional technology. It includes: - Flow length and pressure drop measurements for molds with spiral features at 1mm and 1.5mm thicknesses and temperatures of 110C and 220C. - Roctool technology achieved longer flow lengths at 1mm thickness compared to conventional technology at 1.5mm, demonstrating thickness reduction. - Pressure drop was reduced by up to 50% with Roctool technology, showing improved flow. - Overall, Roctool technology at 220C temperature provided the best results with longest flow and significant reduction in pressure drop versus conventional molding.

Pressure Drop between the 2 Sensors vs Mold Thickness at Injection
Pressure = 1000 Bars
Results Evaluations
The graph above shows a flow length for the two thicknesses
at two temperature (110°C and 220°C). By comparing these
curves, a significant reduction in thickness can be observed.
With Roctool technology, we are able to achieve a better flow
length at 1 mm compare to 1.5 mm in conventional
technology. Also, the following diagram shows the pressure
drop measured between the two sensors for the two
thicknesses at 1000 bars of injection pressure. The reduction
of pressure drop in the cavity is important up to 50 %.
GLOBAL COMMENTS & RECOMMENDATIONS
temperature is 220°C regarding to the trials performed with this material. We obtain the longest flow with an important
reduction of the pressure drop compared to the conventional mold temperature. Also, we demonstrated that we could
reduce the thickness of injected part from 1.5 mm to 1 mm.
Note : All the injection trials and the pressure measurements were carried out according to the protocol defined by RocTool (injection process, 2 heating sides,
cold sprue, mold design).
All pressure data are measured using eDart system (RJG).
