Definitions

  • the invention relates to a pressing tool and a method for producing a pressing tool.
  • the pressing tool comprises a structured pressing surface.
  • Pressing tools e.g. in the form of press plates, endless belts or embossing rollers, are used in the woodworking industry, for example, to produce furniture, laminates or panels, i.e. general workpieces.
  • the workpieces are pressed with the pressing surface of the pressing tool, so that the workpieces have surfaces corresponding to the pressing surface.
  • WO 2009/062488 A2 discloses a press plate with a structured press surface.
  • the structured press surface includes a structure that has a mountain-like surface with valleys and heights.
  • a workpiece in the form of a material plate with a structured surface can be produced by means of the pressing surface.
  • the structured pressing surface comprises a full-surface chrome layer that rests against the material plate during pressing.
  • the structured press surface is produced by deep etching.
  • WO 2015/036070 A1 discloses a pressing tool with a structured pressing surface.
  • the structured press surface is produced by superimposed metal layers.
  • a mask is applied at least once in order to cover partial areas and at least once a metal layer is applied to the uncovered areas in order to build up the structured press surface consisting of elevations and depressions. These two process steps are repeated until a desired structure depth of the structured press surface is reached.
  • the structured pressing surface can then be provided with a hard chrome layer.
  • WO 03/016034 A1 discloses a further press plate with a structured press surface. In order to reduce wear on the press plate, the structured press surface is provided with a coating made of carbon with diamond-like layers and a surface hardness of over 1800 HV according to Vickers.
