摘要: A production process includes introducing the material to be moulded into a mould, placing the mould in an envelope comprising a vacuum port; creating a low pressure in the envelope by formation of a gas flow through the vacuum port; deforming the mould; stopping the gas flow; and applying pressure on at least a portion of the mould, optionally with interposition of the envelope, at least after the gas flow is stopped.
