Abstract
The invention relates to a method for producing a foam-backed molded component, the method comprising the following steps: a) introducing a cover material in a mold (100), the mold (100) having a negative-profiled surface (310); and b) generating and maintaining a vacuum and/or negative pressure on the side of the cover material facing the mold (100); and c) pouring a foam material in the mold (100); and d) closing the mold (100); and e) molding the foam material; and f) opening the mold (100) and removing a foam-backed molded component, the foam-backed molded component having a profiled surface.
Claims11
A method for producing a foam-backed molded component, the method comprising the following steps:
- a) introducing a cover material in a mold, the mold having a negative-profiled surface, wherein the cover material is a real leather, a bonded leather, an imitation leather, a textile, a film, a composite material, or a mixture thereof;
- b) generating and maintaining a vacuum or negative pressure on the side of the cover material facing the mold;
- c) pouring a foam material in the mold, the foam material comprising a polyurethane foam;
- d) closing the mold;
- e) molding the foam material such that a size and prevalence of foam bubbles are essentially uniform over the foam material in all areas;
- f) opening the mold and removing the foam-backed molded component, the foam-backed molded component having a profiled surface corresponding to an inverted version of the negative-profiled surface of the mold;
- and
- wherein the cover material has the profiled surface comprising a plurality of indentations and protrusions with a height difference formed by at least one indentation and at least one protrusion, wherein the height difference is designed as a continuous and contiguous surface, and wherein the profiled surface further has at least one step with a step height of at least 5 mm.
A molded component comprising
- a cover material and
- a foam-backing,
- the cover material having an inner side and an outer side, wherein the outer side of the cover material has a profiled surface and the foam-backing being disposed on the inner side of the cover material;
- wherein the profiled surface comprises a plurality of indentations and protrusions with a height difference formed by at least one indentation and at least one protrusion, wherein the height difference is designed as a continuous and contiguous surface, the profiled surface further having at least one step with a step height of at least 5 mm;
- wherein the cover material is a real leather, a bonded leather, an imitation leather, a textile, a film, a composite material, or a mixture thereof;
- wherein the foam-backing is a polyurethane foam such that a size and prevalence of foam bubbles are essentially uniform over the foam-backing in all areas.
