  • Patent number: 8080193
    Abstract: A method of producing a sound insulation molding with mass and spring, wherein both mass and spring are produced on the basis of the same material, in particular polyurethane. For the formation of a mass, reaction substances and fillers are brought into a mold, in particular sprayed in or injected, and brought to reaction. The spraying in or injection is thereby controlled such that the reaction substances and the fillers are supplied in locally different quantity and/or composition into the mold, dependent upon the sound damping to be locally achieved together with the spring, which is then formed on the so-formed mass in the same mold through formation of foam. Through this, with surfaces to be sound insulated which are of the same geometry, three-dimensional moldings of the same geometry can be produced with both different acoustic and also mechanical behavior in predetermined series.
