C-MOLD Post Filling + Juncture Loss for Amorphous Plastics


Test ID  
G-013

   
Description  
Properties needed to perform a C-MOLD injection mold-filling and packing simulation, incorporating pressure drops in runners and gates, are generated. These include Bagley corrected viscosity vs. shear rate at three temperatures (two in the processing range and one below); thermal properties, PVT data. The entrance pressure loss (Bagley correction) is applied to the viscosity data; the residual contraction pressure loss is correlated to shear stress. 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-012 Capillary Rheology with Bagley Correction (1 Temperature)
1x R-018 No-Flow Temperature

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 [details]
1 - parts, any shape [details]
   
Application  
In addition to all the capabilities of the C-Mold Post Filling program, this TestPak enables the juncture loss calculation which permits the simulation of pressure drop across runners and gates due to extensional effects.
