Characteristics of STS630 Based Metal Injection Molding Products on Powder Size, Sintering and Heat Treatment Conditions

Abstract:

This study proposes the research method to examine through experiment the mechanical properties of final products based on the size and sintering temperature of powder particle during STS630 powder based metal injection molding and heat treatment processing condition after the sintering. The feedstock for the injection was manufactured based on STS630 powder with the diameter of 7.0±1.0μm and 8.0±1.0μm and the sintering was carried at 2 temperature conditions of 1300°C and 1355°C after the injection and debinding process. Heat treatment conditions of sample after the sintering were divided into 2 types thus final samples of total 8 cases were manufactured. Then, the 5 types of mechanical properties test were conducted. Optimal processing conditions for MIM molding and heat treatment of STS630 powder could be established based on it.
