A novel process for manufacturing of injection molded metal, ceramic, and CERMET parts, in a manner amenable to high-volume, low-cost manufacturing, comprising the steps of forming a mechanical mixture of metal and/or ceramic powders at room temperature, a binder and a liquid carrier, said carrier being a solvent for the binder at elevated temperature; supplying the as-mixed components to the inlet hopper of an injection molding machine or extruder; molding or extruding green parts; and then drying and sintering the green parts to obtain net or near-net-shape finished metal, ceramic or CERMET parts.
