Moldflow CRIMS Shrinkage


Test ID  
G-114

   
Description  
Properties needed to perform a Moldflow injection mold-filling/packing/shringage simulation are generated. These include viscosity vs. shear rate at three temperatures; thermal properties, PVT data. Viscosity data and PVT data are fit to Moldflow models. Shrinkage measurments are performed by Moldflow to determine the Corrected Residual In-Molded Stress (CRIMS) model coefficients. Ready-to-load data files are provided. Because these measurements are performed at an outside lab, standard turn-around time is approximately 4 weeks, and no economy service is available.    
Included Tests  
# Test Id Test Name
1x D-020 PVT (Isothermal Heating)
3x R-011 Capillary Rheology (1 Temperature)
1x R-018 No-Flow Temperature
1x T-015 Specific Heat
1x T-103 Thermal Conductivity Scan
 
Options  
A fast turnaround alternative is the [G-007] non-CRIMS TestPak, which is found to be particularly well suited to fiber-filled plastics. [G-007] is available in 5 business days.  
Data  
Moldflow .udb data files 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  
25 - kg of pellets [details]
1 - parts, any shape [details]
   
Application  
There are two approaches to Moldflow Shrinkage/Warpage simulation. CRIMS and non-CRIMS. Either approach can be used for running Fill + Pack + Warp , a simulation that solves for filling, post-filling, shrinkage and warpage of the part. Additionally, with CRIMS data you can run the MF/Shrink (Fill+Pack+Shrink) simulation which determines a recommended shrinkage allowance that can be used to cut the mold. The simulation will provides an indication of whether critical tolerances can be met with this allowance and also a spatial representation of the validity of this allowance across the part.
