摘要: The production of multi-layer mouldings (17) from a sheet (6) injection-moulded behind with a resin can be simplified by the sheet (6) being deformed in an injection mould by means of a fluid pressure medium, in particular nitrogen, at at least 20 bar and the deformed sheet (6) injection-moulded behind with resin directly thereafter in this injection mould, a pressure keeping the deformed sheet (6) in position being maintained during the injection-moulding behind.
