In the method, a tubular roll blank is made by bending out of a planar sheet or by means of centrifugal casting.
It originally had two lines consisting of sand casting and centrifugal casting.
Cylindrical castings , suited to thermal insulation applications at high temperatures, are formed by a centrifugal casting process.
The invention relates to foundry work in particular to the technology of centrifugal casting of blanks for producing rollers used in machines for continuous casting of blanks.
Centrifugal casting is used to establish a gradient profile of reinforcement particulate (12) densities in a carrier matrix (10) of a polymer resin and in an aluminum alloy.
The film can be contacted onto a substrate by spin casting.
The invention is adaptable to spin casting for encapsulating electronic circuitry, among other uses.
A spin molding apparatus and a battery cell are also provided.
A material to be molded is introduced into a centrifugal molding tool.
The material has an exterior surface facing the molding tool and an interior surface defining an interior cavity.
Spin casting apparatus is described which comprises two mould plates (62, 90), which are rotatable about the vertical axis of a column (30).
A spin cast method of producing the tire is disclosed and dependent upon a curing period of the polymer chosen.
