Thermography in plastics industry

Wide application range of thermography in plastics industry

  • Thermography allows specific tempering of injection moulds and deep-drawing
  • Thin plastic films are highly transparent and require special filters for their measurements

Details about Plastics Industry

Thermal optimisation of moulds

Temperature distribution of plastics in injection moulds and for deep-drawing is a critical aspect for the quality of manufactured moulded bodies. Contacting measurements are just as much extensive as the application of pyrometers. In contrast to that, infrared camera systems offer the advantage to provide a complete picture of moulds or moulded bodies’ temperature distribution. However, moulds consist of metal and, therefore, reflect background radiation. A thermographic analysis is carried out much easily when measuring the moulded body itself. Attention should be paid to the fact that temperature measurement is ensued immediately after opening the mould and before the moulded form has been put out, so that this new product has hardly cooled down. Thus, the temperature of the mould can be indicative of the moulded result’s temperature. The high frame rate (of up to 60 Hz) of InfraTec’s camera series VarioCAM ® high resolution ensures a precise thermal image acquisition at the exact point in time. Moreover, due to the integration of stationary infrared camera systems, such as VarioCAM ® hr head, into production processes, it is possible to regulate the mould’s temperature in case of temperature deviations.

Infrared thermography to monitor the film production

Measurement of plastic films by means of filtering

Temperature represents an important quality aspect in the manufacturing process of thin plastic films. This measurement can be carried out without any contact by applying infrared camera. Nevertheless, attention should be paid to the high transparency of the plastic films. A solution for this problem is provided by InfraTec’s special infrared camera systems of the camera series ImageIR ® which can be equipped with spectral filters and, therefore, are able to filter background radiation out. These infrared camera systems also feature high frame rates of more than 10 KHz, especially for the acquisition of fast extrusion processes accurate in every detail.

Infrared Thermography Applications at “Kunststoff-Zentrum in Leipzig (KuZ)“

The infrared thermography is an adequate instrument for non-contact temperature measurements. In this way, absolute temperatures, temperature distributions and relative temperature changes can be measured and tracked within dynamic conditions. The capabilities of infrared thermography systems are multifaceted. As a result, applications in all kind of industries exist. Due to relative good emission ratios of many plastics, infrared thermography is suitable for the extended characterisation of plastic processing technology and its optimisation. This application report exemplifies infrared thermography applications for plastic processing and inspection technologies at the KuZ.
