4. 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 (70°C and 180°C). By comparing these
curves, a significant reduction in thickness an be observed.
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 48%.
GLOBAL COMMENTS & RECOMMENDATIONS
temperature is 180°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.
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).
