SIMCO offers a variety of charging bars and electrodes, depending on the specific applications and conditions. These bars are connected to a DC high-voltage generator. A strong, ion-saturated electrical field around the single polarity high voltage points forces the material to a reference earth. The material is charged by the ions. Being attracted by different polarities, the surfaces temporarily cling together. There are various methods of temporarily charging materials electrostatically, using a SIMCO Chargemaster system.
The point charging bar R23ATR is used wherever target-specific electrostatic charges need to be applied even at high temperatures. For instance in edge trim adhesion in flat film production.
Using the point charging bars R23ATR, both outer edge zones of the film are fixed directly downstream from the flat film extrusion die to prevent neck-in.
The point charging bar R23ATR can be operated with one, two or three emission tips. The tips are interchangeable. The geometry of the tips is adjustable depending on application. This means that the point charging bar R23ATR may be used horizontally or vertically even in confined spaces.
Many production processes and processing stages require materials to be bonded firmly for limited periods. The bonds must not leave any traces and must not be allowed to damage the material surfaces when the materials are eventually separated.
The adhesion through controlled static charges provides the ideal solution in these cases: the R130A / R131A / EXR130A charging bar is designed for applying the specific charge quantity. High-resistance materials such as paper, cardboard, plastics etc. are interlocked for brief periods or fastened to conductive surfaces, without the need to use adhesives.
The design of the R130A / R131A / EXR130A charging bar allows its use in perfect harmony with the intended purpose. In combination with the Eltex high voltage generator models this effective charging system ensures productivity and quality improvements in the most varied production areas.
The charging bar EXR130A is available for use in the Ex zone.
