Starting material for a flat-domed molded plastic part, in particular a housing part, and molded part created therefrom

摘要

In order to reduce the wall thickness of housing parts produced by means of plastic injection molding and equipped with decorative layers, such as battery covers of mobile devices, it is recommended to change to a starting material that is a fiber composite material equipped on one side with the decorative layer, from which starting material the housing part is formed in a deep drawing process. Even if a thick decorative layer the outer surface of which is highly embossed for haptic reasons is applied, the resulting wall thickness remains far below the wall thickness for a housing part that can be produced by means of injection molding. An even further reduction of the wall thickness is achieved if a fiber composite material is used as the deep drawing starting material for the shaped part, the decorative material being directly foamed or injected onto the surface of the fiber composite material.
