This document summarizes the results of a study comparing conventional injection molding technology to RocTool technology using two different spiral mold thicknesses. The RocTool technology achieved significantly longer flow lengths and lower pressure drops between sensors compared to the conventional technology, especially at a mold temperature of 200C versus 90C. Graphs show improvements in flow length of up to 57.5% and pressure drop reductions of up to 45.6% with the RocTool technology. The report recommends a mold temperature of 200C for this material to obtain the longest flow with an important reduction in pressure drop.

4. Flow Length improvement vs Injection Pressure in function of Mold Temperature/Mold Thickness
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, a significant flow improvement can 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 41%.
GLOBAL COMMENTS & RECOMMENDATIONS
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.
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).
