C-MOLD Post Filling for Amorphous Plastics
Test ID
G-012
Description
Properties needed to perform a C-MOLD injection mold-filling and packing simulation are generated. These include viscosity vs. shear rate at three temperatures (two in the processing range and one below) PVT data. Viscosity data are fit to Cross-WLF model and PVT data are fit to a Tait equation.
Included Tests
| 1x | D-020 | PVT (Isothermal Heating) |
| 3x | R-011 | Capillary Rheology (1 Temperature) |
| 1x | T-015 | Specific Heat |
| 1x | T-103 | Thermal Conductivity Scan |
Options
More advanced TestPaks are available to simulate shrinkage and warpage.
Samples
: 1 kg of pellets
[details]: 1 parts, any shape
[details]Application
According to C-MOLD, this 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.
