The paper report the optimisation study of the injection parameters for the feed stock consist of Stainless Steel powder (SS 316L and binder consist of Polyethylene glycol (PEG), Polymethyl methacrilate (PMMA) and Stearic Acid (SA) in Metal Injection Molding (MIM) process. Results from the study showed that the optimum injection parameters for the injection temperature, pressure at holding unit, injection pressure and molding temperature are between (130-140℃), (850-900 bar), (1000-1200 bar) and (30-40℃) respectively.
