Abstract
The invention relates to a method for the production of plastic molded skins which are built up by consecutively melting multiple plastics onto each other. The surface of the forming tool is partially covered with a covering or mask during the melting of a first plastic powder and the first plastic powder is applied to the forming tool by a powder spray method. Thereafter, the covering or mask is removed from the surface of the forming tool and the second plastic powder is applied to the surface of the forming tool and to the first plastic powder by rotation sintering.
