摘要： A method for producing a lightweight, sound insulating covering (1, 1′, 1″, 1″) for a body component of a motor vehicle, in particular a lightweight dashboard covering, wherein the covering (1, 1′, 1″, 1″) is produced as a foamed, sound absorbing molded part in a single-stage operation by injecting a reactive mix, comprising polyol and isocyanate, into a cavity (11) of a foaming tool (9), wherein before and/or during the injecting, at least one predetermined surface portion (17), defining the cavity (11) of the foaming tool (9), is temperature-controlled in such a manner that the foamed molded part comprises an integral substantially pore free skin (1.1) with a thickness of at least 0.5 mm on one side, and comprises an open porous surface (1.2) and/or a thinner, sound permeable skin (1.4) on its side opposite to said skin (1.1).

摘要： The invention relates to a lightweight sound insulating lining (1) for a body component of a motor vehicle, in particular in the form of a lightweight front wall lining, comprising a sound absorbing layer, a sound insulating layer which is directly connected to the sound absorbing layer and substantially air tight, as well as an adjoining foam layer (1.3), wherein the sound absorbing layer (1.1) is made of a porous absorber, preferably a fiber fleece or a foam, which has an air permeability in the range of 150 to 2000 liters/m2s at a test pressure of 100 Pa. The sound insulating layer (1.2) is formed by an integral skin layer of the foam layer (1.3) with a thickness of at least 0.5 mm, and is integrally joined to the porous absorber by back-foaming the porous absorber substantially without foam penetration therethrough. Furthermore, a method for manufacturing such a lining is disclosed.
