A process for the preparation of a least partially as a covering of the composite body serving in particular sound generators and using same

摘要

To simplify the manufacture of a composed of a carrier part (2) and a sound-absorbing / sound absorber layer (3) made of foam material composite body (1), on the one hand, a for the formation of the absorber layer (3), a foam material - blank (5) and, on the other hand, a for the formation of the carrier part (2) which serves for the plastic or plasticizable mass (6) in a compression moulding die (4) or injection molding tool and is introduced there the mass (6) with application of pressure and, if appropriate, heat to the support part (2) and formed for the formation of the outer shell member (1) with the foam material - blank (5) deformed absorber layer (3) connected.
