  • Method and device for producing plastic molded skins having different subregions
    Patent number: 8617446
    Abstract: The present invention relates to a method and a device for producing plastic molded skins having different subregions. For this purpose, before melting the first plastic material, a region of the molding tool surface (2) is covered with a separate energy self-sufficient mask (3). After the unmasked region of the molded tool surface (2) has been coated, the mask (3) is removed, and in a second manufacturing step the exposed subregions of the molding tool surface (2) is coated with a different plastic material, the two subregions of the plastic skin bonding with each other.
