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  
# Test Id Test Name
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.  
Data  
A .fit file and accompanying material property data are provided. You can also create udb files as well as exports for other injection molding CAE using your Matereality CAE Modeler software.  
Samples  
1 - kg of pellets [?]
1 - parts, any shape [?]
 		   
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.
