All pressure data are measured using eDart system (RJG). Results Evaluations The graph above shows a flow length for the two thicknesses at two temperature (90°C and 200°C). By comparing these curves, part reduction could be done from 1,5 mm to 1 mm. 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%. GLOBAL COMMENTS & RECOMMENDATIONS The HD Plastics™ characterization trials shows a significant flow length and pressure drop improvement. The optimum temperature is 200°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.
