DescriptionTitle: Micro product development and micro tool design by means of micro injection molding process simulations Abstract: Similar to conventional injection molding, process simulations are an effective tool in micro injection molding for the optimization and simulation-aided design of micro components as well as the mold and the molding process. Although the demand for simulations in micro injection molding rises, their application must be conducted carefully, because available software packages are actually made for macroscopic injection molding. In the presented work, the proper implementation, meshing, and modeling strategy for micro components is reported. Process simulations are applied to two microfluidic devices (micro distributor and micro mixer) fabricated in plastic and exhibiting feature sizes down to about 100 μm and aspect ratios of up to three. The goal of the simulations is the investigation of the general filling of each part and the influence of different gate configurations. The simulation results are used to evaluate the gate designs and find the most suitable one with regard to the process window, the filling behavior, and possible part quality criteria such as part flatness. An outlook on limitations and possible improvements rounds up the talk.
