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
| 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.
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.
