Shortcut on the Way to Freeform Optics
Virtual Mold Trials. The manufacture of plastic optical components usually involves a highly iterative process during development of the molded part and mold construction. Reason for this is the uncertainty associated with the injection molding behavior. The case example from a research project demonstrates how a virtual mold trial can replace this stepwise approach, which also results in considerable cost reductions.
