Plastics | Flat Film and Sheet Extrusion

Avoiding Surface Defects

In flat film and sheet extrusion the molten mass is pressed through a wide slit die and then processed further using a calender. In this process the film is gradually cooled. The infrared sensors measure the temperature of the film at various points, thereby monitoring the process. Infrared cameras also allow cracks and surface defects to be detected.
