    • 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.
    • 描述了一种制造用于机动车辆的仪表板,门或侧面装饰板的方法,其具有用于气囊瓣的预定断裂线。 为了实现这一点,将搪料材料引入到可以被加热到成型温度的模具中,并且确定腻子膜的形状,其中搪瓷材料通过旋转模具而分布和沉积在加热的模具表面上,然后烧结 胶凝 冷却模具后,通过模塑将模糊膜从模具中取出。 为了创建预定的断裂线,使用在要产生的预定断裂线的位置处在其模具表面上具有分隔件的模具。 通过在施加粉末和/或胶凝材料的同时模具的受控旋转和/或定位,可以实现将浆料的层厚减小至建立预定断裂线的程度。
