Among them, degreasing is a very important link in the process flow of MIM products, which is a process of removing the binder contained in the formed blank (brown blank) before sintering, so that the binder is gradually discharged from different parts of the blank along the tiny channels between the particles without damaging the high strength of the blank. The degreasing process aims to shorten the degreasing time as much as possible under the condition of no defect and deformation, ensure that the chemical components of the degreased brown embryo are controlled within an allowable range, and prepare for the next sintering process.
