  • Injection-molding tool and method for producing an injection-molded part
    Patent number: 10093046
    Abstract: The invention relates to an injection molding tool for producing an injection molded part, in particular made of plastic, having an injection mold which has a cavity corresponding to the negative of the shape of the injection molded part to be produced, wherein a plasma nozzle, which is configured to produce an atmospheric plasma jet, is attached to the injection mold in such a way that an injection molded part produced in the injection mold can be impacted in the injection mold with a plasma jet.
    Type: Grant

  • Process for manufacturing a headlight lens
    Patent number: 9421718
    Abstract: The invention relates to a method for producing an optical lens element, in particular for illuminating purposes, in particular for producing a headlight lens for a vehicle headlight, in particular for a motor vehicle headlight. A preform made of a transparent plastic, which is amorphous in particular, is molded in an injection mold using an injection molding method. The preform is removed from the injection mold, in particular before the average temperature of the preform falls below the melting temperature of the plastic and/or the flow temperature of the plastic, and the preform is subsequently pressed into the lens element, in particular the blank, using a final contour mold.
