Abstract
For the production of a particularly dimensionally stable cable set, the single conductors (22) of the cable set are initially inserted into a cavity (8) of a foam tool (2) and a foaming material is subsequently filled in. To dispense with involved and expensive hydraulic equipment, a vacuum is generated to press a top half (6) and a bottom half (4) of the foaming tool (2) against each other. For this, vacuum channels (6) are preferably provided, which extend along sides of the cavity (8).
Claims4
A method for producing a particularly dimensionally stable cable set having a plurality of single conductors, said method comprising:
- inserting the plurality of conductors into a cavity of a foaming tool that comprises a top half and a bottom half;
- generating a vacuum, which is effective between the bottom half and the top half to seal the cavity, inside a vacuum space arranged adjacent to the cavity and provided by vacuum channels on the side and along the length of the cavity;
- and, introducing a foaming substance into the cavity to surround the plurality of single conductors with foam.
A method for producing a particularly dimensionally stable cable set having a plurality of single conductors, said method comprising:
- inserting the plurality of conductors into a cavity of a foaming tool that comprises a top half and a bottom half;
- generating a vacuum, which is effective between the bottom half and the top half to seal the cavity, inside a vacuum space arranged adjacent to the cavity;
- introducing a foaming substance into the cavity to surround the plurality of single conductors with foam;
- additionally generating a vacuum in the cavity;
- and adjusting different vacuums inside the cavity and in the vacuum space, with a lower vacuum being adjusted in the cavity than in the vacuum space.
