Static charge between two surfaces can create enormous adhesion forces. These forces can also be used in a productive way in all kinds of production applications e.g.
The materials need to be bonded have to pass a charging electrode. Opposite to the charging electrode a ground reference is positioned, e.g. an idle roller. A static charge can be applied ranging from 3 kV to 120 kV depending on the material thickness, speed and adhesion force required. Used equipment in this application:
The HDR charging bar suits high velocity applications. Each individual point being fitted with a resistor, so the chance of spark-over is strongly reduced.
The new standard function Current Control will enable you to set a constant current vs a constant voltage. This will provide a much more stable charging and will compensate contamination and emitter pin wear automatically.
