The invention relates to a method for discontinuous forming of plastics by volume repression in a cavity. The method is characterized in that forming energy is introduced via at least two mobile elements of the cavity surface. At least one half of the mould contains one or more elements which are mobile in relation to it. At least some of~ the forming energy is introduced by the relative movement of these elements. Only part of the cavity surface is involved in the introduction of the forming energy. The invention also relates to a device for carrying out this method, and the components produced by this method or in this device.
L'invention concerne un procédé de formage discontinu de matières plastiques par refoulement de volume dans une cavité. Ce procédé consiste à introduire l'énergie de formage par l'intermédiaire d'au moins deux éléments mobiles de la surface de la cavité. Au moins une moitié de moule renferme un ou plusieurs éléments mobiles par rapport à elle. Au moins une partie de l'énergie de formage est introduite par le mouvement relatif de ces éléments et uniquement une partie de la surface de la cavité est impliquée dans l'introduction d'énergie de formage. L'invention concerne également un dispositif pour mettre en oeuvre ledit procédé ainsi que des composants produits selon ce procédé ou dans ce dispositif.
