Abstract (en)
[origin: WO2013081459A1] The present invention relates to a method for plastically deforming a body, whereby the body is positioned in a mould cavity of a mould between a first mould section and a second mould section. The body is subjected to a deformation force, which is directed towards a mould surface of the first mould section, in order to plastically deform the body and to conform it at least substantially to the mould surface. A first fluid is admitted into the mould cavity on a side of the body, which is averted from the first mould section, which comprises a gas, compressed under pressure, which has departed from a gaseous state of aggregation. In a mould cavity, which is at least partly filled with the first fluid, a second fluid is admitted at a temperature above a boiling point of the first fluid in order to allow the first fluid to expand, while forcing the body against the mould surface of the first mould section.
