A method for producing a 3D-substrate that is coated with a laminate, the method comprising the steps:
- using a forming tool including
- a lower stationary tool half which includes a tool trough that envelops a tool trough interior in which a lowerable table is arranged,
- an upper tool half which includes a pressure bell that envelops an interior space, wherein the pressure bell is arrangeable in a closed position adjacent to the tool trough and in a raised release position that is remote from the tool through,
- wherein the following steps are performed in the raised release position of the pressure bell:
- introducing a 3D-substrate that is to be coated into the forming tool and fixing the 3D-substrate to the lowerable table in the tool through, lowering the lowerable table to a lower dead center, and
- arranging a one layer or multi-layer initially flat laminate that has a visible side and an opposite contact side or a flexible transfer foil that is provided with a blank made from the laminate at a circumferential edge of the pressure bell or adjacent thereto,
- providing an arrangement in the closed position of the pressure bell,
- wherein the laminate or the transfer foil separates the interior spaces arranged in both tool halves pressure tight from each other, and
- a pressure medium pressure of less than or equal to 30 kPa is initially set in the tool trough interior, and
- an initial vacuum of less than or equal to 30 kPa is set in the pressure bell interior space and subsequently a pressure medium pressure of 2-18 bar is set in the pressure bell interior space by introducing a fluid pressure medium pressure fluid, and
- the laminate is heated while both forming tool interior spaces are provided with a pressure medium pressure of less than or equal to 30 kPa,
- wherein the tool through includes at least one retraction cavity for at least one movable heat radiator arrangement which includes at least one upward radiating heat radiator, and
- wherein the heat radiator arrangement is moved in the closed pressure bell position and after setting the pressure medium pressure at less than or equal to 30 kPa within the tool trough interior space from its retraction cavity into an interior space between the laminate material and the 3D substrate to be coated and the laminate is heated in a controlled manner by the upward radiating heat radiators, and
- the heated laminate is applied over a glue layer to the 3D-substrate and coated thereto,
- setting ambient pressure in both forming tool interior spaces, separating the two tool halves from each other, lifting the pressure bell and removing the 3D-substrate that is coated with the laminate from the tool through interior and processing the laminate as required, characterized in that
- the glue layer provided with activatable glue is arranged at the contact side of the laminate and activated by the activated upward radiating heat radiators also the glue arranged at the laminate material contact side is activated, and
- the movable heat radiator arrangement is additionally provided with activatable downward radiating heat radiators, and
- after introducing the heat radiator arrangement into the intermediary space between the laminate material and the 3D-substrate to be coated
- the surface of the 3D-substrate to be coated is heated in a controlled manner by the activated downward radiating heat radiators and after completion of the heat treatments the heat radiator arrangement is moved back into its retraction cavity.
