A decorative ornamental part, e.g. control key, is produced by cutting operation to produce a clearance gap such that the stamping punch carrying out the cutting operation remains as a place-holder in the cut contour of the clearance gap during the injection operation, and that the injection operation producing a bond ensures the exact connection of the contour of the cut free inner part to the frame of the ornamental part. Production of a decorative ornamental part, e.g. control key, comprises cutting operation to produce the clearance gap such that the stamping punch carrying out the cutting operation remains as a place-holder in the cut contour of the clearance gap during the injection operation, and that the injection operation producing a bond ensures the exact connection of the contour of the cut free inner part (33) to the frame of the ornamental part. The ornamental part has a symbol (32) in relief that is defined by a clearance gap (34) free as far as possible of webs and connections in the frame (31) of the control key. It is back-injected with a plastic melt by the plastic injection molding process. An independent claim is also included for a device for producing a decorative ornamental part, e.g. control key, comprising cutting tool (17, 18) for holding the cut free inner part in the injection mold upper part. |
