Low cost water based binder system was developed for shaping ferrous, nonferrous metals and/or ceramics parts by injection molding processes. The process comprises the steps of preparing a mixture containing a gel-forming powder comprising carrageenan, metal and/or ceramic powders, de-ionized water and a gel-strengthening additive. The mixture is injection molded to produce self-supporting articles. The present invention provides a direct compounding and molding of metal and/or ceramic feedstock. Additionally, a coating composition comprising gelatine, water and a metal and/or ceramic powder is used to form coating layers on selected materials.

Aqueous binder formulation for metal and ceramic feedstock for injection molding and aqueous coating composition

Additionally, a coating composition comprising gelatine, water and a metal and/or ceramic powder is used to form coating layers on selected materials.

A process for adjusting the level of water or water soluble additives in aqueous-based powder injection molding compounds for the purpose of recycling scrap material, controlling shrinkage or rehydrating dry feedstock. Depending on the objective, the process may require material granulation equipment, equipment for the addition or removal of water and mixing equipment. The molding compounds may be comprised of either recycled scrap material before being heat-treated or dry, virgin feedstock material.

Recycle methods for water based powder injection molding compounds

A composite molding compound comprising a combination of metal and ceramic powders is disclosed. The powders are combined with a binder, a liquid carrier and other processing additives in a manner to provide uniform distribution of two phases in a material format that facilitates the molding of complex parts at relatively low pressures and temperatures using conventional injection molding machines. The products formed from these molding compounds may be designed with tailored physical and mechanical properties such as thermal conductivity, thermal expansion coefficient, density, elastic modulus and wear properties.

Metal/ceramic composite molding material

This invention provides a process for forming sintered, molded articles having improved dimensional stability. More particularly, this invention pertains to process for forming heat sinks. This process includes forming a substantially uniform copper composition comprising a polysaccharide binder, water, and copper particles; molding the copper composition under conditions sufficient to form a solid molded intermediate; and sintering the solid molded intermediate at a sufficient temperature and for a sufficient time to form a heat sink.

Aqueous nonferrous feedstock material for injection molding

This invention provides a composition and a process for forming sintered, molded articles having improved dimensional stability. More particularly, this invention pertains to a composition having a sugar additive that increases the solids loading potential of the composition and a process for forming injection molded articles therefrom. Increasing the solids loading potential of the composition, enables the formation of metal or ceramic articles attaining about 98-99% of their theoretical maximum density, without cracking or shrinking significantly during sintering.

Aqueous injection molding binder composition and molding process

A composition for forming molded metal containing articles having improved stability. More particularly, a corrosion resistant composition for forming injection molded articles having a sodium silicate corrosion inhibiting additive. The corrosion inhibitor prevents metal oxidation when a metal containing powder is mixed with a water based binder, providing stability to the article and preventing generation of hydrogen gas. This significantly enhances the shelf life of the moldable composition prior to molding.

Stable aqueous iron based feedstock formulation for injection molding

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

Recycled, reground ceramic powder is mixed with a liquid carrier, a binder and processing additives to form a material useful for molding complex-shaped parts at relatively low pressures in conventional injection molding equipment.

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.
