Thermal Optimisation of Moulds

Thermal image of a plastic cover

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.

    10 GigE Interface for a Strong Increase in Output

    The 10 Gigabit Ethernet interface of the high-end camera series ImageIR® opens this extremely fast transmission standard with a NIC specially developed by InfraTec. This works with optical or electrical transceiver modules that are easy to change and are called SFP+.

    Different 10 GigE fiber SFP+ transceivers allow transmission ranges of up to ten kilometers with the same low sensitivity to electromagnetic interference. A corresponding standard SFP ensures backward compatibility with the conventional GigE interface. This combination allows the ease of use of the cameras with the 10 Gigabit Ethernet interface in existing systems - though at a reduced transmission rate.

    Separate Filter & Aperture Wheel – Spectral Thermography

    The combination of a separate filter and aperture wheel, allowing a total of 30 freely selectable combinations, is prerequisite for an universal application in measurement tasks with high object temperatures and in the field of spectral thermography. The neutral density filters used for signal attenuation or the combination of spectral filters and apertures reliably prevent interference effects.
