The document reports on a study comparing the flow and pressure performance of conventional and Roctool molding technologies. Testing showed that with Roctool technology, a 1mm thick part could be molded where conventional required 1.5mm, and pressure drop was reduced by up to 76%. Flow length was significantly improved at both 90C and 220C mold temperatures when using Roctool technology. The results demonstrate that Roctool technology allows for thinner parts and reduced pressure drop compared to conventional molding.

4. Flow Length improvement vs Injection Pressure in function of Mold Temperature/Mold Thickness
Results Evaluations
The graph above shows a flow length for the two thicknesses
at two temperature (90°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 76 %.
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).
