Abstract

Dimensional variation in powder injection molding (PIM) is one of the key issues for broadening the use of this process to a greater number of applications. Process capability has only been addressed by a few studies in the technical literature and manufacturing details still remain proprietary. In this study, the dimensional variability of a metal injection molding (MIM) process for 316 L stainless steel is reported. The main variable investigated in this part of a series of experiments on variability is the powder loading of the feedstock. A design of experiments (DOE) approach is used to statistically analyze the effect of the powder loading on the variability of multiple dimensions of a typical MIM component after molding and debinding.
