This document summarizes test results from injection molding trials using Roctool technology compared to conventional technology. The trials showed that using a mold temperature of 290°C with Roctool technology significantly improved flow length and reduced pressure drop compared to a conventional temperature of 150°C. Specifically, flow length increased over 60% and pressure drop decreased over 50% with Roctool technology. Additionally, Roctool technology allowed reducing the part thickness from 1.5mm to 1mm while achieving equivalent flow length.

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).
The HD characterization trials shows a significant flow length and pressure drop improvement. The optimum
mold temperature is 290°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.
Results Evaluations
The graph above shows a flow length for the two
thicknesses at two temperature (150°C and 290°C). By
comparing these curves, a significant reduction in thickness
can be observed.
With Roctool technology, we are able to achieve an
equivalent 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 33%.
