Electrically conducting gasket as well as a process and appatratus for its fabrication

摘要

A process for producing an electrically conducting seal made of an elastic hardenable material containing electrically conducting particles, comprises extruding the material in plastic form from an extruder onto a primary surface. The particles are mixed with the material before extrusion takes place and are magnetic. After the material is applied to the primary surface (5), it is hardened and an electromagnetic plate (7) is located over the material to create a magnetic field. The latter acts on the magnetic particles causing them to extend to the plate, so finally forming the seal. The seal material hardens under the influence of temperature or UV light. The electromagnetic plate used to carry out the process, has a profiled section and a housing.
