The structure of the two or more shaped plates distributes the atmospheric pressure that acts on the evacuated multi-layer arrangement in such a way that said structure remains stable.
The rods (9) are then inserted at their ends in perforated mould plates (15, 17).
The shaped plates have a plurality of structural elements in opposing directions, formed from the shaped plates, said elements being alternate elevations and depressions.
The invention relates to a vacuum-insulation element which comprises a multi-layer arrangement that can be evacuated and has at least two shaped plates, each plate having a continuous edge region that forms a sealing surface.
The spring-loaded elements serve to produce a circular folded seam around the multilayer moulded plates.

24 plates have been moulded into the gullies that are created by ground erosion (through the movements of pedestrians).
The invention relates to a vacuum-insulation element which comprises a multi-layer arrangement that can be evacuated and has at least two shaped plates, each plate having a continuous edge region that forms a sealing surface.
The fine, low-porous cast plates are also homogenised by extended heat treatment and undergo thermal stress relief.
Still further, by arranging a plurality of resins for disposal, it is possible to effectively use the resins when yielding multiple molded plates from one resin sheet.
ISO 15527:2007 specifies the requirements and test methods for solid flat compression-moulded sheets of polyethylene (PE‑UHMW and PE‑HD) without fillers or reinforcing materials.
ISO 15527:2010 specifies the requirements and test methods for solid flat compression-moulded sheets of polyethylene (PE‑UHMW and PE‑HD) without fillers or reinforcing materials.
