N2 - Micro-injection molding is a branch of micro-electromechanical system (MEMS) technology. Actually, the research of micro-injection molding is just beginning in the world. In this study, three-dimensional non-Newtonian computations of micro-injection molding were performed. The governing differential equations were discredited by using control volume finite element method (CVFEM). The analysis with different polymers (such as PS, PC, PMMA), process parameters (injection time-mold temperature-injection temperature and injection pressure) uses to simulate the micro-house for example. In order to obtain optimum result, the simulation introduces Taguchi method to discuss the influence of each parameter in micro-injection molding. In this study, the results show that the mold temperature is the most important factor on process parameters. The mold temperature on micro-injection molding is higher than the glass transition temperature of plastic material. The best suitable material is PMMA.
