Abstract
A process for shaping threaded metal and ceramic parts from powders and molding compositions therefor is disclosed. Parts produced by this process are formed net shape without the need for machining or other finishing operations. The process comprises forming a mixture containing metal powders, ceramic powders or mixtures thereof, a gel-forming material and an aqueous gel-forming material solvent, and molding the mixture in a mold containing internal and/or external threads under conditions of temperature and pressure to produce a self-supporting threaded article.
