C-MOLD Post Filling + Juncture Loss for Amorphous Plastics
Test ID
G-013
Description
Properties needed to perform a C-MOLD injection mold-filling and packing simulation, incorporating pressure drops in runners and gates, are generated. These include Bagley corrected viscosity vs. shear rate at three temperatures (two in the processing range and one below); thermal properties, PVT data. The entrance pressure loss (Bagley correction) is applied to the viscosity data; the residual contraction pressure loss is correlated to shear stress. Viscosity data are fit to Cross-WLF model 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 the juncture loss calculation which permits the simulation of pressure drop across runners and gates due to extensional effects.
