Product overview

The EC150 thermal imaging system is an automated surface inspection system used to detect, measure and classify defects in extrusion coating, coextrusion and lamination processes. This system provides unique functions for managing the quality of plastic film extrusion processes.

Over the entire width of the flow channel of the extruder, temperature and viscosity changes in the local melt flow can cause "waves". Or the "running" edges, gaps and edges tear in the extruded film. The EC150 system uses the MP150 Process Imager to continuously monitor the temperature distribution and width of the extruded melt curtain to automatically detect such defects.

EC150 extrusion system software

The EC150 system monitors the extrusion process to display temperature data as line graphs (contours) and thermal imaging images. Personal data and images can be printed or archived for future analysis.

Automatic edge detection

This automatic fan function unique to EC150 can continuously monitor the melt curtain from the extruder die and provide automatic edge detection. The automatic sector is suitable for measuring plastic sheets of different widths. Temperature differences, unacceptable fluctuations, edge running or edge tearing can be detected immediately, and if a malfunction or defect occurs, an alarm will be triggered to take quick corrective actions.

Extrusion coating

The processes of extrusion coating (on top of the substrate) and extrusion lamination (between two substrates) similarly press molten thermoplastic resin onto a moving web through a horizontal die. Substrates include paper, aluminum, cards and printing films.
