Abstract
A method of producing dashboards, door or side trim panels for motor vehicles with a predetermined breaking line for an airbag flap is described. To accomplish this, slush material is introduced into a mold which can be heated to a molding temperature and determines the shape of the slush membrane, where the slush material is distributed and deposited on the heated mold surface by rotating the mold and is then sintered and gelled. After cooling the mold, the slush membrane is removed from the mold by unmolding. To create a predetermined breaking line, a mold having a divider on its mold surface at the location of the predetermined breaking line to be created is used. By controlled rotation and/or positioning of the mold while applying the powder and/or gelling the slush material, a reduction in the layer thickness of the slush material to an extent that establishes a predetermined breaking line is achieved.
