摘要

The method involves compressing a plate having fine-particle silicon dioxide as a semi-finished product. The plate is cut on a measurement corresponding to the dimensions of a filling, particularly silicon dioxide after the evacuation. The metal sheets (11) are provided with knob-like impressions (17) that are provided as the edges (12). The metal sheets are arranged on the processed plate, so that the impressions contact the outer side of the plate. An evacuating arrangement is molded with a plastic material, like polyurethane.
