Abstract (en)

[origin: EP1860384A2] The method involves manufacturing individual parts that are connected with each other by foaming and connecting the parts to an insulated casing. The parts are processed at impact surfaces after the foaming process, where the processing takes place by manufacturing groove and spring connection or through the production of a gradation. The processing takes place after cooling under observation of a relaxation time, where the casing has an outer layer (1) and an insulation layer (2).
