Abstract: The invention uses supercritical fluid technology for removing the binder in the powder injection moulding (PIM) parts. The invention comprises of the feedstock formulation and its supercritical debinding process. In the debinding system, pressure and heat are applied to the carbon dioxide (CO2) to a certain level, in such a way to transform the CO2 to supercritical state. The supercritical CO2 is used as a solvent to remove the binder in the PIM parts.
