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.

Low pressure injection molding of metal and ceramic threaded components

A process for molding metal knife blades from powders and molding compositions therefor are disclosed. Parts produced by this process are formed near net shape without the need for machining or other finishing operations. The process comprises forming a mixture containing metal powders, a gel-forming material and an aqueous gel-forming material solvent, and molding the mixture in an injection molding machine under conditions of temperature and pressure to produce a self-supporting knife blade having a sharp edge.

Low pressure injection molding of knife blades from metal feedstocks

A process for molding flat tableware from powders and molding compositions therefor are disclosed. Parts produced by this process are formed near net shape without the need for machining or other finishing operations. The process comprises forming a mixture containing a metal powder, a gel-forming material and an aqueous gel-forming material solvent, and molding the mixture in an injection molding machine under conditions of temperature and pressure to produce a self-supporting flat tableware article.

Low pressure injection molding of flat tableware from metal feedstocks

A method for rapidly manufacturing soft tooling from organic polymer-based resins and reinforcement filler materials for use in an injection molding machine to make complex metal and ceramic parts from powders. The cost to produce the tooling is relatively low and the manufacturing time is relatively short compared to conventional processes for making metal tooling. The finished parts are near-net shape, requiring little or no machining, and have excellent sintered properties.

Low pressure injection molding of metal and ceramic powders using soft tooling

A method for rapidly manufacturing metal tooling utilizing injection molding techniques is described. Preferably, steel tooling is manufactured for use in an injection molding machine to produce near-net shape complex parts in high volume. The method is relatively inexpensive compared to conventional techniques for manufacturing complex metal tooling suitable for the rapid fabrication of complex shaped parts by conventional metal, ceramic and plastic processing.
