The invention relates to a method and to a device for producing a molded part that is preferably configured as a heat insulating and/or sound absorbing element, particularly a press-molded part made of mineral fibers, for example stone and/or glass fibers. The invention further relates to a molded part as a heat insulating and/or sound absorbing element, particularly as a lining part in vehicle construction, produced using a generic method, made of mineral fibers, particularly stone and/or glass fibers. In order to further develop a method, a device, and a molded part having high flexibility with respect to the molded parts to be produced and/or configure the molded part in a simple and diverse variety, according to the invention the mineral fibers are accumulated as flakes and/or granules, with or without bindings agents, having a predetermined bulk density and/or predetermined basis weight and/or predetermined binding agent percentages, filled in a mold, and subsequently pressed to form a molded part, particularly a press-molded part.

L'invention concerne un procédé et un dispositif de fabrication d'un élément moulé de préférence conçu en tant qu'élément d'isolation thermique et/ou phonique, notamment d'un élément moulé par compression composé de fibres minérales, par exemple de fibres de pierre ou de verre. L'invention concerne également un élément moulé conçu en tant qu'élément d'isolation thermique et/ou phonique, notamment en tant qu'élément de garniture dans l'industrie automobile, fabriqué au moyen du procédé selon l'invention, composé de fibres minérales, notamment de fibres de pierre ou de verre. L'invention vise à améliorer un procédé, un dispositif et un élément moulé avec une grande flexibilité en ce qui concerne les éléments moulés à fabriquer, ou à réaliser l'élément moulé dans une diversité simple et polyvalente. A cet effet, les fibres minérales sont agglomérées en tant que flocons et/ou granulés, remplies dans un moule avec ou sans liants, avec une densité en vrac prédéfinie et/ou un grammage prédéfini et/ou des teneurs en liants prédéfinies, puis moulées en tant qu'élément moulé, notamment en tant qu'élément moulé par compression.
