Investigation on Green Properties of Magnesium Alloy AZ31 Feedstocks Molded via Metal Injection Molding Process

Abstract

Powder loading is an important parameter because of its role in part shrinkage, dimensional stability, and final density. Thus, this research investigated the properties of the molded magnesium feedstocks in determining the best powder loading for producing magnesium part through metal injection molding process. In this research, the feedstocks with three magnesium alloy AZ31 powder loading of (63, 65, 67) vol%, was prepared comprising the binder component of paraffin wax, high density polyethylene, waste plastic, and stearic acid (PW/HDPE/WP/SA) with weight fraction 55/21/14/10, respectively. After injection molding, the density, diamensional accuracy, and strength of the green part was investigated. The findings reveal that 65 vol% of powder loading resulting to the best green properties.
