摘要
Micro-injection molding is the most important technology in MEMS/NEMS industry for the necessary of scale, velocity and cost by the development of MEMS/NEMS industry and the innovation of MEMS/NEMS industry. It has the advantage of low cost, low interface and small volume in MEMS/NEMS industry. This paper emphasizes the analysis for microstructure of microlens arrays on micro-injection molding. The finite element simulation in a three-dimensional inertia-free, incompressible flow is presented. A control volume scheme with a fixed finite element mesh is employed to predict melt front advancement. The plastic material of microlens arrays is used for PMMA material. The results show the short shot on the filling stage of micro-injection molding. The results also indicate that the melt front first advance into the thickness direction of microlens arrays, and then it goes into the microstructure of microlens arrays.
