Setting up a Gas-assisted injection molding analysis

The following table summarizes the setup tasks required to prepare a Gas-assisted Fill+Pack analysis of a non fiber-filled, or fiber-filled thermoplastic material.

Tip: The optimal number of mesh layers through the thickness is at least 10 for a Gas-assisted analysis using 3D analysis technology.

1 The gas channel mesh must pass diagnostic tests.
2 Gas injection control parameters can be set at the same time as the gas entrance.
3 Manual core/cavity mold temperature assignment is only relevant when not performing a Cool analysis.
