PRO-CON

The reduction of transverse tolerances on blown films is a focus at PLAST-CONTROL. In addition to the actuator used, fast and accurate software is crucial for the good result.

The PRO-CON profile control works with an automatic, segmented cooling ring that regulates the volume of the two cooling air streams and thus achieves an influence on the film thickness in the plastic area.

Existing thin spots in the film are cooled more directly when the melt leaves the die and can therefore no longer expand as much. The film remains thicker at this point.

PRO-CON reacts accordingly in the opposite direction to thick spots in the film. Depending on the raw material and product handling, the film circumference tolerance is reduced to a possible minimum. The cooling rings are available in six sizes.
