Process and components for fixing bulkhead parts

摘要: A molding is described, the outer edge region of which comprises a thermally expandable material that has high coefficient friction in relation to metal or plastic. In its inner this an aperture and/or recess for receiving mounting aid. The suitable as sealing and acoustically active bulkhead part with aid forces can be fixed mechanically cavity structural components without these having exhibit bores, apertures other devices fixing part.
