摘要

Micro system technology (MST) is including Optic, Mechanism, Electricity, Material, Control and Chemistry, etc. It can miniaturize product and increase its function, quality, reliability and add-value. The size of micro product is closing to nanometer. Micro-injection molding is a branch of micro system technology. Actually, the research of micro-injection molding is just beginning on the world. In this study, numerical simulations of three-dimensional micro-injection molding are performed. The governing differential equations are discredited by using control volume finite element method. The analysis with different polymers (such as PP PA POM) process parameters (injection time mold temperature injection temperature and injection pressure) uses to simulate the micro-gear 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.
