Flow Length improvement vs Injection Pressure in function of Mold Temperature/Mold Thickness
TRADE NAME VICTREX® PEEK GRADE
The graph above shows a flow length for the 2 thicknesses at
two temperature (190°C and 250°C). By comparing these
curves, a significant reduction in thickness can be observed.
Also, the following diagram shows the pressure drop
measured between the two sensors for 1,5 mm of thickness
at 1000 bars of injection pressure. The reduction of pressure
drop in the cavity is important up to 26%.
GLOBAL COMMENTS & RECOMMENDATIONS
The HD Plastics™ characterization trials showns a significant flow length and pressure drop improvment. The optimum mold
temperature is 250°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).
