    摘要: 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.
