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 definition 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® HD head, into production processes, it is possible to regulate the mould’s temperature in case of temperature deviations.

Analysis of the Thermal Conductivity in Nano- and Mesostructured Polymer Systems

New materials with precisely controlled optical and thermal transport characteristics can make a large contribution to resource-saving thermal management. Scientists of the University of Bayreuth are pursuing this vision. They use infrared thermography to quantitatively determine thermal conductivity in nano- and mesostructured polymer materials.

Measurement of Plastic Films by Means of Filtering

Infrared thermal imaging to monitor the film production

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.
