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, Poisson’s ratio, and thermal expansion coefficient. Viscosity data are fit to Cross models and PVT data are fit to a Tait equation.

[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.
