Micro Powder Injection Moulding Using Nanosized Powders

Abstract:

Micro powder injection moulding (μPIM) is one of the micro-moulding technology applied today in high-volume fabrication of metal and ceramic micro-components. The current study presents the micro powder injection moulding (µPIM) of 316L Stainless Steel nanopowder-polymer mixtures. 316L SS powders have been blended with a binder system which consists of Polyethylene Glycol (PEG), Polymethyl Methacrylate (PMMA) and Stearic Acid (SA). All the feedstock prepared shows homogeneity and pseudo-plastic behaviour which is suitable for μPIM process. The results showed that increase in nano powder content would improve the powder loading, injection and sintering temperature. Moreover, high physical and mechanical properties of the sintered specimen have been achieved under vacuum atmosphere. The above results indicate that application of nano powder has the potential to provide micro powder injection moulded parts with nearly full density, fine microstructure. The binder system is environment-friendly, has low viscosity-temperature and suitable to prepare feedstock for μPIM.
