                                Description

                                Properties needed to perform a Moldflow injection mold filling, packing, and shrink/warp simulation are generated. These include viscosity vs. shear rate at three temperatures (two in the processing range and one below), thermal properties, PVT data. Additionally, the following mechanical properties are derived from tests on specimens cut from injection molded plaques: tensile modulus in flow and cross-flow direction Poisson’s Ratio in 12 and 23 directions, thermal expansion coefficient in flow and cross-flow directions and in-plane shear modulus. Data are fit to Moldflow models. This TestPak provides Gold-Gold-Gold .udb files.

                                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. Recommended for plastics that are expected to show anisotropy, such as fiber-filled materials.
