N2 - Micro metal injection moulding (μ-MIM) needs more sophisticated techniques than the conventional MIM. The use of finer metal powders is one of the solutions to improve the dimensional accuracy and surface roughness of sintered products. This study aims to investigate the effects of hybrid micro/nano powders 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 mould without pelletizing was used. Small dumbbell specimens were produced with changing the binder content and the fraction of nano-scale copper powder. The effects of nano-scale copper powder addition on the tap density of mixed powder, the viscosity of feedstock and microstructure of sintered bodies were discussed.
