Patent ID: 7018583

Claim:
A method for producing a component from a pulverulent starting material by mixing a powder together with auxiliaries, comprising binders, resulting in the formation of a free-flowing mass, after which a preform is produced from the mass by means of powder injection molding, then some of the auxiliaries are extracted in that the preform is heated in a tank and exposed to a solvent stream, after which the preform is sintered, thus giving rise to the component, characterized in that the extraction comprises a heating-up phase during which the temperature of the pre-form is continuously or incrementally increased and a solvent in the form of a compressed, supercritical treatment gas flows around the preform, and further characterized in that, during the heating-up phase, a heating rate is set in the range from 0.1° C./min to 5° C./min [0.2° F./min to 9° F./min].
