<p>Moulding apparatus for the manufacture of plastic parts from a liquid material, polyvinyl chloride (PVC) in the form of a plastisol or organosol, or also a mixture of at least the two basic components (polyol and isocyanate) in the form of a liquid of a polyurethane elastomer with application of an exothermic reaction in order to cause the polymerisation and/or the crosslinking of the plastic material. The reaction is carried out, in the open air, in a mould (M) to which a high-frequency electrical field is applied. <IMAGE></p> |
