发明名称 Metod för att åstadkomma en formpressad produkt samt vid metodens utövning utnyttjat formverktyg
摘要 The present invention relates to a method for producing a compression moulded product by means of a moulding tool (1) and the said moulding tool. The method is characterised in that both a carrier, comprising sheets of a fibre material impregnated with a first thermosetting plastic material, and a film pack comprising at least one sheet of film which includes a second thermosetting plastic material, which may be the same thermosetting plastic material as the first, are introduced into the moulding tool (1). The moulding tool (1) is then closed and preheats the carrier and the film pack in order to make the plastic material in these viscous. In the next stage a force is applied in order to prepress the mould halves (3a, 3b) of the moulding tool against one another, thereafter producing venting. A second force is then applied in order to again press the two mould halves against one another. Finally the moulding tool (1) is opened for removal of the product thereby produced, comprising the compression moulded carrier and the film pack integrated therewith.
