6.2. Process Simulation in Polymer Processing

Process simulation in polymer processing is an established procedure nowadays in science and industry. In science, a number of simulation tools specified and optimized for selected processes exist. For injection molding in particular, commercial FEM-simulation tools with comfortable graphic interfaces are available [3]. Process simulation focuses on mold filling and the reduction of shrinkage and warpage. The simulation results are fundamental for the determination of the molding window and the design of molding tools. Moreover, prior process simulation can save time and costs and allows the adaptation of the process parameters to sophisticated designs. Nevertheless, it has to be taken into account ...
