Abstract

Mass produced of desired molded parts is possible with Powder Injection Molding (PIM). This work focused on the rheological properties of stainless steel (SS) 17-4PH with a binder system of palm stearin (PS) and polyethylene (PE). The critical powder volume percentage of SS17-4PH at 75vol% was obtained. Based on such value, the powder loadings used in this work were 71vol%, 72vol% and 73vol%, were mixed with 60wt% PS and 40wt% PE. A capillary rheometer was employed for the rheological studies where the relationship between shear rate and viscosity was investigated. In addition, the value of flow behavior index, n for each powder loading was also computed in order to identify the injectability and activation energy, E of feedstocks. It was found that powder loading at 72vol% gave the best rheological properties.
