An incorrectly set frost line height causes many problems, such as width fluctuations, production instability, basket markings or deviating mechanical film properties.

System operators often have problems setting the visually poorly recognizable frost line correctly.

In addition to incorrect operator settings, influences such as changes in the ambient temperature (day/night), the cooling air temperature or the melt temperature lead to undesirable fluctuations or drifting of the frost line height. This is often only noticed when the product quality has already been impaired.

The new KDvision-Frost frost line scanner from Kdesign solves these problems and makes the frost line visible at all times.

The current position can be seen on a clearly visible LED strip on the device and is also displayed as a numerical value and trend. If the position runs out of a defined monitoring window, an alarm is triggered.

The operator can implement production specifications precisely during the set-up and avoid setting errors.

In conjunction with a new blown film line, the KDvision frost is a further building block for the digitalization of the production process and the basis for monitoring, long-term archiving and control loops for keeping the frost line constant.
