The document summarizes injection molding trials of a plastic material using conventional and RocTool technologies. The RocTool technology demonstrated significant improvements in flow length and reduction in pressure drop compared to the conventional method. At a mold temperature of 290°C, the RocTool technology obtained the longest flow length with an important reduction in pressure drop. Additionally, part thickness could be reduced from 1.5mm to 1mm using the RocTool method.

4. The HD Plastics™ characterization trials show 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.
Comment: Pressure drop between two pressure sensors has been carried out only at 1 mm of thickness
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).
