C-MOLD Post Filling for Semi-Crystalline Plastics
Test ID
G-017
Description
Properties needed to perform a C-MOLD injection mold-filling and packing simulation for semi-crystalline materials are generated. These include viscosity vs. shear rate at three temperatures (two in the processing range and one below); thermal properties, high cooling-rate PVT data. Viscosity data are fit to Cross-WLF model and PVT data are fit to a Tait equation.

[details]Application
According to C-MOLD, the Post-Filling module simulates the packing stage where a hold pressure is applied to the plastic to compensate for material shrinkage. Use C-MOLD Post-Filling simulation to determine how much pack/hold pressure to use, when to decrease the pressure, and how long to apply the pressure prior to gate freeze. Adding fast-cool pvT data is expected to increase the accuracy of the prediction for crystalline materials.
