Cast Film Extrusion

A charging applicator at each edge of the film on the chill roll applies a static charge to the extruded film as it contacts the chill roll. The static charge effectively prevents ‘neck-in’ of the film.

An ionising blower installed above the film directs the ionisation at the film

Used Devices

Static generation equipment pinner claw of Simco-ION
Used Device (A)

Pinner Claw charging electrode

Simco-Ion Europe offers various electrodes, including the 5 Point, Linear 6 Point and the Pinner Claw, specifically for spotcharging small surfaces. These electrodes are also ideal for edge charging in cast-film extrusion processes. The material applied permits high temperature use. The electrodes are resistor-protected to avoid sparkover. The points are replaceable.
Used Device (B)

CM5-30 high voltage generator

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.
