This report summarizes a study comparing injection molding using conventional versus Roctool technology. Testing was conducted using a spiral mold injected with PEI material at different temperatures and mold thicknesses. Key results found that with Roctool technology at 270C, significantly longer flow lengths and lower pressure drops were achieved compared to conventional technology at 170C. Specifically, a 1mm thickness achieved better flow than a 1.5mm thickness at lower pressure using Roctool technology. Overall, the Roctool process demonstrated improvements in flow length and pressure drop of up to 51% compared to conventional technology.

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 (170°C and 270°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
1500 bars of injection pressure pressure(170°C vs 270°C). The
reduction of pressure drop in the cavity is important up to
51%.
GLOBAL COMMENTS & RECOMMENDATIONS
The characterizationtrials show a significant flow length and pressure drop improvement. The optimum mold
temperature is 270°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.
Comment: Pressure drop between two pressure sensors has been carried out at 230°C with Roctool technology because
aquisition at higher temperature was not possible.
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).
