Computer-aided engineering for gas-assisted injection molding

The current CAE analysis generates intermediate results for both the filling and post-filling stages, enabling the filling behaviors of polymer and gas to be 'visualized' throughout the entire process. Based on these progressional results, molding problems associated with the process and their causes can be detected and resolved before the tool is cut. These comprehensive predictions also provide valuable insight from which crucial engineering know-how and design guidelines can be quickly acquired. All the results reported in this article were obtained from C-GAS FLOW, a three-dimensional CAE analysis program for gas-assisted injection molding.
