Abstract

In this experimental work, Micro Powder Injection Molding (μPIM) was carried out with stainless steel feedstock. The feedstocks with powder loading between 60 v/o to 62 v/o were prepared with 5μm stainless steel powder, Polyethelena Glycol (PEG), Polymethyl Methacrilate (PMMA) and Cellulose Acetate Butyrate (CAB). The main objective was to determine the homogeneity and flow characteristics of the mixture. Capillary rheometer method was performed to define the sensitivity of viscosity to shear rate and temperature for the mixture. The rheological properties were investigated and analyzed through relevant equations. Results show that the flow ability and characteristics of μPIM feedstocks highly depend on the mixture composition. Feedstock at 61 v/o exhibited the most suitable characteristics when mixed at temperature of 130oC with a rotor speed of 30rpm.
