Abstract
The invention relates to a method, and an apparatus, for the production of articles which consist of filler-containing synthetic material, in particular a foam, wherein flowable reactants, at least one of which has previously been charged with filler, are injected into a mixing zone under predetermined injection pressures, wherein the reaction mixture is subsequently introduced into a mold. Cellular materials such as flexible, semi-rigid, rigid or structured foam based, for example, on polyurethane or isocyanurate, and also non-cellular materials such as elastomers, may be produced by methods of this type.
