SimPGM - A commercial simulation tool for precision glass molding industry

The precision glass molding is an efficient manufacturing process for the replicate production of non-spherical glass lenses. In industrial applications, due to lack of understanding of the molding process, there are still several challenges for mold and process design, e.g. thermal shrinkage and index-drop. Based on both ANSYS and ABAQUS platform, an integrated numerical simulation tool - SimPGM - was developed to provide scientific understanding of the molding process for solving of the above mentioned problems and thus providing an optimized layout of the process as well as the tool insert geometry for the industrial applications.
