A two-dimensional simulation of thermal dabinding in powder injection molding is presented. Special interest is placed on deformation and stress generation due to polymer removal by thermal debinding. The strains and stresses arising from polymer content change, gas pressure, and temperature change are considered. The simulated results reveal that the strain and stress in the compact are dominated primarily by polymer content change. The nonuniform distribution of polymer content during the polymer removal process is attributed to nonuniform flow of the polymer; attendant nonuniform deformation and stresses in the compact can lead to failure.
