Abstract

Abstract

The electromagnetic vibration field was introduced into the injection process of metal powder injection molding (MIM). The density and mechanical properties of the green body and sintered samples were systematically evaluated. Meanwhile, the microstructure of the green body and sintered samples was investigated by SEM and microscope. The effects of different vibration parameters on the performance of injection green body were studied to obtain the most suitable vibration parameters. The results show that when the vibration field is introduced into the MIM injection process, the density and properties of green body and sintered samples are significantly improved compared with the static injection proces. With the strengthening of the vibration field, both the density and properties increase firstly and then decrease, which is related to the feeding fluidity. The technology can provide a possibility for breaking through the technical bottleneck of preparing large parts with MIM.
