摘要:
A glove having a glove liner adorned with at least one injection-molded component that provides the glove with specific characteristics tailored to a specific glove application. The liner may comprise a fabric and/or an elastomeric material. The position, composition, and/or contour of the injection-molded components define the characteristics of the glove.

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.

摘要:
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.

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.

摘要:
A debinding and sintering method is employed to produce consolidated net shape articles from metal powders including 17-4PH stainless steel alloy by metal injection molding using an agar based aqueous binder. The debinding and sintering step can be combined into one cycle to economically produce components for the consumer and aerospace industries.
摘要:
A spark plug electrode wire composed of an iridium-rhodium alloy exhibits improved erosion resistance and enhanced durability in leaded and unleaded fuel environments. The alloy is formed into a wire having high thermal conductivity, low electrical resistivity, good oxidation resistance, good corrosion resistance, good wear resistance. It exhibits desirable work function in pure metals and alloys such as iridium and iridium-rhodium. The wire is inserted into the center electrode of the spark plug and brazed to an Inconel base metal and copper core thereof using a silver-based brazing alloy. After electrical engine dynamometer testing for 200 hours, an improvement in erosion resistance as high as eight fold was observed with an 60% iridium-40% rhodium alloy, when compared to a conventional 90% platinum-10% nickel alloy. The iridium-rhodium spark plug electrode wire can be used to minimize erosion and wear resistance in leaded and unleaded fuel environments.
