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 50 %. 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).
