| Summary: | 碩士 === 國立中央大學 === 機械工程研究所 === 87 === Metal injection molding which procedure of manufacture is kneading which mix metal powder and binder to mould it, debinding and sintering. Besides it had distinction of powder metallurgy, complexity of shape and density of product of metal injection molding are better than powder metallurgy. The crux in all of process of metal injection molding is debinding, not only many kinds of defect are appeared but also cost increased when the process makes long time. The paper focus wicking of thermal debinding and analysis deeply by Taguchi method to find controllable factors to shorten debinding time and achieve well-quality. At last, we consider the exchange of quality and capacity of manufacture, we got the best combination of parameter in our experiment, A1B2C1D1. It indicated large particle size ratio, low viscous binder, spherical powder shape and homogeneous packing density.
