Abstract

Extraction of polyethylene glycol (PEG) from metal injection molding compact has been investigated at various powder loadings, leaching temperatures and times, referred as independent variables. Central composite rotatable design (CCRD) of experiments is used to study the effect of these independent variables on the brown body's strength, or a dependent variable. This paper reports the use of Response Surface Methodology (RSM) technique to optimize the processing factors for solvent debinding gas atomized 316L stainless steel (of average size 11.2 pm-fine and 19.6 pm-coarse) for maximum brown strength. For fine powder (11.2 pm), to achieve maximum brown strength of 5.6 MPa, the optimised values were as follow; powder loading 64% volume, debinding temperature of 60°C and debinding time at 2 hours. Meanwhile from the optimized values of powder loading (64% volume), debinding temperature (59°C) and debinding times (3 hours), the maximum brown strength for coarse powder obtained was 5 MPa. This protocol provides improved opportunities for solvent debinding techniques particularly to extract PEGs from the moulded components mathematically without experimentation. Keywords: Solvent
