  • Stainless steel aqueous molding compositions
    Patent number: 6268412
    Abstract: Molding compositions for shaping parts from stainless steel powders are disclosed. The process comprises the steps of forming a mixture comprising stainless steel powder, a gel-forming material having a gel strength, measured at a temperature between 0° C. and about 30° C. and a gel comprising about 1.5 wt % of the gel-forming material and water, of at least about 200 g/cm2, and water, and molding the mixture at a temperature sufficient to produce a self-supporting article comprising the powder and gel. The preferred gel-forming material is an agaroid and the preferred molding process is injection molding.
    Type: Grant
