Abstract:
A process for forming microporous metal parts, the process comprising(a) providing a feedstock comprising metal powder and a binder having a melting point; (b) injection molding the feedstock to provide a porous green part, the injection molding comprising (1) heating the feedstock to a temperature greater than the melting point of the binder to provide a plasticized feedstock; (2) mixing a pore-forming agent with the plasticized feedstock; and (3) filling a mold with the plasticized feedstock; (4) permitting the plasticized feedstock to solidify in the mold; (c) debindering the porous green part to substantially remove the binder and provide a debindered porous green part; and (d) sintering the debindered porous green part.
