ABSTRACT:
The invention relates to a method for the production of plastic skins by pulverizing, wherein a powder is placed on a forming tool and a plastic skin is formed by sintering. A partial area of the forming tool, at least during a first pulverization step, is made inaccessible to the powder by means of a mask with a preferably inflatable sealing edge. The forming tool is provided with a separating web along one edge of the partial area whereon the mask rests during the first pulverization step with the sealing edge. The invention also relates to a corresponding sintering tool and a plastic part which comprises a plastic skin produced according to inventive method of production, on one surface thereof. The inventive method can produce two-color plastic skins, which are usually used as surface decorations, while effectively avoiding scrap.
