Case study applications in numerical simulation for precision glass molding process

In the last few years, a flexible and reliable simulation tool was developed in Fraunhofer IPT for glass molding process. In this work, case study applications are introduced to demonstrate the capabilities of this simulation tool in glass shrinkage prediction and mold design optimization. Most challenging simulation tasks including ultra thin aspehrical lens, wafer level lens arrays and cylinder lens arrays are introduced and followed with detailed process analysis result. The simulation results present an effective and reliable functionality of the simulation tool which has potential capacity also for diverse industrial applications.
