Predict, map weld lines prior to injection molding


Processing problems are best solved before parts are molded. Now, with the help of the interface SigmaLink, weld lines can be predicted and mapped into FEA software with the injection molding simulation software SigmaSoft, and taken into consideration in the structural design of injection molded parts.

Sigma Plastic Services now offers this new functionality with its injection molding simulation software. The simulation of the cavity filling in injection molding allows identification of regions where weld lines could form, not only on the surface but also through the part's thickness, with a 3D approach. With this data, it is possible to transfer this 3D information into FEA software so that the drop in mechanical properties in these regions is accounted for when undertaking structural design....
