Metal injection molding (MIM) is a near net shape manufacturing technique for producing small, complex, precision parts in mass production. MIM process is manufacturing method that combines traditional shape-making capability of plastic injection molding and the materials flexibility of powder metallurgy. The process consists of the following four steps: mixing of metal powder and binder, injection molding to shape the component, debinding to remove the binder in the component, sintering to consolidate the debound parts. In this research, the physical and mechanical properties of metal injection molded 17-4 PH stainless steel were investigated with the variation of sintering temperatures (1300 °C - 1360 °C) and atmosphere conditions (argon and vacuum conditions). The relative density, microstructure, distortion, and hardness are measured and analyzed in this study. The results show that highest relative density of 87%, relative homogeneous shrinkage and high hardness are achieved by sintering at 1360 °C for 1.5 hours and argon atmosphere. At the same sintering temperature and time, sintering in vacuum shows lower relative density (81%) than that in argon condition due to pores growth. The pore growths were not observed in the argon atmosphere. It can be concluded that sintering stages more rapidly under vacuum condition. The hardness measurements result also showed that high hardness is obtained by high density parts. The optimum average hardness obtained in this study is 239 HV. However, the hardness properties results are still lower than 280 HV according to MPIF Standard 35 for MIM parts.

Hot embossing process has emerged as a viable method for producing small, complex, precision parts in low volumes. It provides several advantages such as low-cost for molds, high replication accuracy for microfeatures and simple operation. The adaptation of this process for producing high fidelity hot embossed feedstock based metallic powders without the need for machining of the die mold is outlined. This was achieved through a combination of powder metallurgy and plastic hot embossing technologies to produce net-shape metal or hard materials components. In this paper, the manufacturing of molds that are suitable for the production of microfluidic systems using the replication technique is discussed. Variations of parameters in the replication process were investigated. An experimental rheological study was performed to evaluate the influence of the mixing parameters on the rheological behavior and thermal stability of 316L stainless steel feedstock. The effects of the solid loading on the feedstock rheological properties and tolerance control as well as mechanical properties and microstructures were investigated.
