Abstract: Metal powder injection molding (MIM) can be used to manufacture the high performance precision parts with the special shape in large quantities and low cost, which is regarded as one of the research hotspots in the field of the advanced manufacturing technology. The MIM technology was summarized in this paper, including the powder preparation, the binder selection, the mixing, the injection, and the subsequent debinding and sintering. The development, status, and new technology of MIM were introduced, the numerical simulation of MIM was deeply analyzed, and the development trend of MIM was prospected.
