Abstract
A method in which various kinds of powdered or granular materials such as metal, ceramic and the like are put into a metal cylindrical container which can be plastically-deformed, or in the space between a container and a core or a substrate, the surroundings are sealed so that the powdered or granular materials do not leak out, the container is locally pressed by a small roller, and the locally pressed treatment is provided to the whole container region. Therefore, the internal powdered or granular materials are pressurized to a uniform density without regard to selective parts, and the materials are formed to various shapes by means of the local pressing.
Claims18
A method for forming a powdered or a granular material comprising:
- (a) putting a volume of a powdered or granular material comprising at least one member selected from the group consisting of a metal, a ceramic and carbon in a metal cylindrical container,
- (b) sealing said container,
- (c) locally pressing an outer surface of said container with a local pressing member while rotating said container about a longitudinal axis of said container as a rotating center, and
- (d) progressively moving said local pressing member along said outer surface of said container to deform said container outer surface, whereby said powdered or said granular material is formed to a shape conforming to the deformed outer surface of said container.
A method for forming a powdered or a granular material comprising:
- (a) loosely setting at least one cylindrical or rodlike core member in a metal cylindrical container to form at least one space between said core member and an inner surface of said container,
- (b) putting a volume of a powdered or granular material comprising at least one member selected from the group consisting of a metal, a ceramic and carbon in said at least one space between said core member and said inner surface of said container,
- (c) sealing said container,
- (d) locally pressing an outer surface of said container with a local pressing member while rotating said container about a longitudinal axis of said container as a rotating center, and
- (e) progressively moving said local pressing member along said outer surface of said container to deform said container outer surface, whereby said powdered or said granular material is formed to a shape conforming to the deformed outer surface of said container and an outer surface of said core member.
A method for forming a powdered or a granular material comprising:
- (a) loosely setting at least one metal cylindrical container in a hollow part of a substrate having at least one edge of a sectional round hollow part exposed to an outer part to form at least one space between said substrate and an outer surface of said container,
- (b) putting a volume of a powdered or granular material comprising at least one member selected from the group consisting of a metal, a ceramic and carbon in said at least one space between said outer space of said container and said substrate,
- (c) sealing said edges of said substrate exposed to said outer part,
- (d) locally pressing an inner surface of said container with a local pressing member while rotating said container about a longitudinal axis of said container as a rotating center, and
- (e) progressively moving said local pressing member along said inner surface of said container to deform said container inner surface, whereby said powdered or said granular material is formed to a shape conforming to the deformed inner surface of said container and an inner surface of said substrate.
