C-MOLD Filling/Cooling + Juncture Loss (Bagley correction)
Test ID
G-011
Description
Properties needed to perform a C-MOLD injection mold-filling simulation, incorporating pressure drop in runner 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. The entrance pressure loss (Bagley correction) is applied to the viscosity data; the residual contraction pressure loss is modeled as a function of shear stress. Viscosity data are fit to Cross-WLF model.

[details]Application
In addition to all the capabilities of the C-Mold Filling/Cooling program, this TestPak enables the juncture loss calculation which permits the simulation of pressure drop across runners and gates due to extensional effects.
