• Inner container is usually made by deep drawing, is thus relatively smooth and therefore offers little possibilities for the attachment of cables and cables. Therefore, usually for attachment of these cables or cables is moved so that they are manually fixed before foaming with adhesive tapes and as "lemon slices" designated spacers and / or mounting clips on the inner container or on the body. Such a mounting for wiring is thus almost inevitably subject to relatively large fluctuations. These fluctuations lead to different flow behavior in the foaming process and consequently also fluctuating insulation values. Due to these variations, the tolerance width of the insulation capacity on the inner container can not be kept small enough. For devices with complex structure of cables and cables, this sometimes leads to disruptions in the production process.
