C-MOLD Isotropic Shrinkage & Warpage (Amorphous Plastics)


Test ID  
G-015

   
Description  
Properties needed to perform a C-MOLD injection mold filling and packing plus shrink/warp simulation are generated. These include viscosity vs. shear rate at three temperatures (two in the processing range and one below); thermal properties and PVT data. Additionally, the following mechanical properties are derived from tests on specimens cut from injection-molded plaques or tensile bars: tensile modulus, Poissonís ratio, and thermal expansion coefficient. Viscosity data are fit to Cross models and PVT data are fit to a Tait equation.    
Included Tests  
# Test Id Test Name
1x D-020 PVT (Isothermal Heating)
1x M-013 Orthotropic In-Plane Shear Modulus (Includes M-010, M-101)
3x R-011 Capillary Rheology (1 Temperature)
1x T-015 Specific Heat
1x T-303 Thermal Expansion Coefficient by TMA
 
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]
10 - tensile bars [details]
   
Application  
In addition to all the capabilities of the C-Mold Post Filling program, this TestPak enables calculations of shrinkage and warpage. Recommended for materials which are not expected to show anisotropy, such as unfilled materials.
