This document summarizes the results of a study comparing conventional injection molding technology to Roctool technology using a spiral mold. Testing showed that with Roctool technology at a mold temperature of 200C, flow length was significantly improved compared to conventional technology at 90C, and the mold thickness could be reduced from 1.5mm to 1mm. Pressure drop between sensors was also reduced by up to 67% with Roctool technology. In conclusion, a mold temperature of 200C is recommended for this material to achieve the longest flow and greatest reduction in pressure drop compared to conventional technology.

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 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 67%.
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. 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).
