<p>The method of producing a three dimensional (3D) carrier part (6) laminated with a layer of material in a molding tool (9), comprises forming a pressure bell (17) with a first mold half (10) and forming the 3D carrier part with a conservative second mold half (160) in a defined arrangement, where the laminate is a flat laminate having a single layer or multilayer, or a flexible transfer film with a cut of such a laminate, and introducing the laminate or the transfer film provided with the laminate cut into the pressure bell of the first mould half. The method of producing a three dimensional (3D) carrier part (6) laminated with a layer of material in a molding tool (9), comprises forming a pressure bell (17) with a first mold half (10) and forming the 3D carrier part with a conservative second mold half (160) in a defined arrangement, where the laminate is a flat laminate having a single layer or multilayer, or a flexible transfer film with a cut of such a laminate, introducing the laminate or the transfer film provided with the laminate cut into the pressure bell of the first mould half, where the pressure such as compressed air is immediately and directly applied into the pressure bell under a fluid pressure of 20-300 bar with the help of the fluid, and forming isolated and laminated 3D carrier part via connecting an active adhesive layer within 5 seconds. The two mold halves are arranged separately in a pressure-tight manner. A heat-activatable adhesive: is activated or prepared in an active state, held on the 3D carrier part and/or the laminate, and is activated at the temperature of 75-130[deg] C, where a part of the heat-activatable adhesive is heated inside the closed mold to its activation temperature or higher temperature by electric heaters or heating elements, which are arranged in the pressure bell of the first mold half; and contains infrared radiation and/or UV light-absorbing photo initiators. The pressure within the interior of the second mold half, in which the 3D carrier part is kept, is lowered to a value of = 30 kPa before introducing the fluid pressure medium into the pressure bell of the first mold half. The laminate after clamping of the laminates or the laminate with the transfer film provided cut after clamping of the transfer film complies a distance to the 3D carrier part between sealing surfaces of the two mold halves, and the laminate or the laminate layer material with the transfer film provided cut after the warming activates the adhesive at the concern side of the layer material on its activation temperature, where after lowering the pressure in the interior of the second mold half to a value of = 30 kPa a distance remains to 3D carrier part before the fluid pressure medium is introduced into the pressure bell of the first mold half. The layered material or the laminate transfer film provided cut complies a distance to 3D carrier part. The molding tool is associated with an evacuable vacuum container, and the pressure in the interior of the second mold half is lowered in such a way that a flow connection is generated between the interior and the pre-evacuated vacuum vessel. The exposure of the laminate or the transfer film laminate with cutting to the high fluid pressure continues for 2 seconds after the laminate or the laminate provided with the film cutting contacted the 3D carrier part for the first time. The heating of the adhesive is carried out simultaneously with or after lowering the pressure in the interior of the second half. A layer of heat-activatable adhesive is applied on the planar side of the material layer by screen printing or transfer printing process or by using direct coating. The laminate comprises a plastic film, which comprises a structured surface on the view side turned away to the 3D carrier part. The cut of the laminate is stored on a transfer film, which is coordinated to the 3D carrier part. The laminate-cutting provided transfer film is clamped in the pressure-tight manner between the two sealing surfaces of the two mold halves that are separated from each other. The laminate cutting located on the transfer film is completed on the 3D carrier part. An independent claim is included for a device for producing a three dimensional carrier part.</p> |
