Micro metal powder injection molding (μ-MIM) needs more sophisticated techniques than the conventional MIM. The use of finer powders is one of solutions to improve the dimensional accuracy and surface roughness of sintered products. This study aims to investigate the effectiveness of nano powder in μ-MIM process. To produce the tiny specimens with high trial efficiency and a small amount of feedstock, a novel experimental machine which can achieve to mold without pelletizing was used. Minute pattern specimens were produced with changing the binder content and the size of copper powder. The effects of particle size of metal powder on the tap density, melt viscosity, and surface roughness, microstructure of sintered parts were discussed.
