Abstract: A vulcanizing mold manufacturing method, and a tire vulcanizing mold are disclosed. Tubular bodies each formed by oppositely arranging the inner peripheral surfaces of both end portions of a plate-shaped body are each arranged so that the gap between both opposite end portions thereof is narrowed and that the tips of both end portions come in contact with the surface of the plaster mold, by inserting and fitting both opposite end portions into a fitting portion of a plate-shaped metal fitting protruding from the surface of the plaster mold. Molten metal is poured over the surface of the plaster mold to embed the tubular body in a mold while exposing the tips of both opposite end portions at the tire molding surface of the mold. The metal fitting is removed from the mold, so that a mold having a small gap between both opposite end portions is manufactured.

Abstract: The invention includes a method of forming a material which comprises at least two elements. More specifically, the method comprises providing an electrolytic cell comprising a cathode, an anode, and an electrolytic solution extending between the cathode and anode. A metallic product is electrolytically formed within the electrolytic cell. The forming of the metallic product comprises primarily electrorefining of a first element of the at least two elements and primarily electrowinning of a second element of the at least two elements. The invention also includes a mixed metal product comprising at least two elements, such as a product comprising tantalum and titanium.

Abstract: An interposition layer (12) is formed on the outside surface of a part (10) made of thermostructural composite material containing carbon, and a metal case is formed by casting molten metal (22) around the part provided with its interposition layer. The interposition layer has closed porosity and it is proof against the metal of the case, such that shrinkage of the metal during cooling is absorbed by compacting or collapsing the porosity of the interposition layer, thereby preserving the integrity of the metal case, and the interposition layer constitutes a diffusion barrier preventing eutetics forming by contact between the metal of the case and the composite material.

Abstract: A method for manufacturing a structural component includes forming a groove in an outer surface of a fiber reinforced body. Molten metal is introduced to an exposed surface of the groove and to a predetermined portion of the outer surface of the body. The metal is cooled in a controlled manner to thermally alter sufficient resin to create a secure interconnection of the metal on the body. The metal adjacent the groove is sized so that it will fail prior to separation of the metal from the body under excessive tensile loads. A portion of the metal remains on the body so that elongation of the component significantly exceeds ultimate elongation of the fiber reinforced body and the cast metal.

Abstract: A method for casting a cast part onto the end of a hollow section places the end of the hollow section in a defined position in a die which is then closed. The end opening in the hollow section is closed in a sealed manner against the penetration of cast material, at least during casting, the molten cast material is introduced into the remaining free space in the die and the hollow section is thereby cast around in a positive-locking manner, at least at the end. To improve the fixing of the hollow sections within the cast part, the hollow section is cooled during the casting of the cast part.

Abstract: Molten metal is die cast directly to and around a surface of a fiber reinforced plastic part in such a way as to actually take advantage of the thermal decomposition of the part resin caused by the hot metal. The molten metal is introduced to the surface and cooled just rapidly enough to allow a controlled, limited resin decomposition to occur at the top surface. Molten metal then flows in and around the exposed fibers, creating a secure interlock.

Abstract: A composite metal article is made by placing a low melting temperature metal to serve as a core within a shell of a high melting temperature metal and by containing and sealing the core within the shell. The assembly constitutes a containerized ingot which is then transported to a forming die where the containerized ingot is heated to soften the core and is then formed to the shape imposed by the die. During the cooling period, the shell is reformed to the core to maintain tight contact and to promote bonding.

Abstract: A composite metal article is made by placing a low melting temperature metal to serve as a core within a shell of a high melting temperature metal and containing and sealing the core without oxides within the shell. The assembly is then transported to a shaping die where the containerized ingot is heated to soften the core and is then formed to the shape imposed by the die. During the cooling period, the shell is reformed to the core to maintain tight contact and bonding.

Abstract: The present invention relates to castings constituted by a metal matrix reinforced by fibres and having outgrowths.Firstly, a reinforcing framework is produced, which is incorporated into the fibrous strengthening member, the complete entity being placed in a mould and the metal matrix is cast. The latter penetrates the fibrous strengthening member and the reinforcing framework. The latter is positioned at the location of an outgrowth which, after solidification of the metal matrix, is consequently reinforced.Application to the production of castings having fixing tabs or lobes.

Abstract: In pipes and the like of relatively heavy section, a boss is formed on the side of the pipe or section by drilling a hole in the pipe, forming a mold around the hole with the hole in relatively vertical position and depositing in the mold and against the walls of the pipe, thereby joining to those walls, electroslag metal which forms a boss on the pipe.
