Polyplastics tool simplifies mold design

Jan. 16, 2023
Its CAE analysis technology for its Duracon POM epoxy resin predicts vacuum voids, allowing users to avoid design problems and more quickly achieve mold trial success.

Computer-aided engineering (CAE) analysis technology Engineering thermoplastics manufacturer Polyplastics is offering a new CAE tool that predicts the occurrence of vacuum voids in injection molded products made of its Duracon POM, an epoxy resin widely used as a metal replacement.

What’s new? Polyplastics’ void-prediction tool, which takes into consideration variables such as temperature, pressure, mold shrinkage and elastic modulus when using Duracon POM. By linking flow analysis with structural analysis, it verifies the shape, molding conditions and effects of changes in the gate position, and visualizes the size of voids as well as the positions in which they will form. 

Benefits Less-expensive, faster development of molds. Users of the CAE tool can predict the risk of voids before creating a mold, reducing the number of mold trials they need to perform and reducing energy use.
