Abstract
This review paper focuses on the metal injection molding process and undesirable defects that occur during part manufacturing. In this paper, common types of metals for injection molding, process parameters, and MIM applications are deeply reviewed from recent research works. MIM process merges the high capability of plastic injection molding technology to produce intricate molds with the advantages of a powder route to process metallic, ceramic, or composites materials. The drawbacks of the MIM process come from diverse technical steps involved in the production of the part (feedstock production, injection, debinding, and sintering). The product quality of MIM is depending on feedstock preparation, mold design, process parameters like temperature and pressure, debinding technique, sintering process, etc. However, the advancement of MIM has proven that can produce very small size and large volume production with low cost when we compare to another manufacturing process. Generally, this study has been presented MIM process parameters, existed defects in MIM and possible remedial solutions, and also future research scope.
