Infrared heat helps to get a good grip

22.09.2015

Did you know that Infrared makes the handle of watering cans more comfortable?

Steering wheels, watering cans and handles shall have a good grip. On no account must they have sharp edges. However, sharp burrs cannot always be avoided when producing plastic parts.

These burrs should be removed reliably and automatically, with not much energy and time consumed by the process.

Infrared emitters, precisely aligned to contours, edges and borders use energy very purposefully.


Heating plastics in seconds, without contact, and in a targeted manner

The wide range of processes used in plastics processing can now be carried using infrared heating technology. Infrared emitters are already well-established in the rapid, homogenous heating of large, flat surfaces.

However, there is a real challenge in manufacturing processes where only very small or curved surfaces, edges, borders or defined contours of the product need to be heated. Why is it necessary to heat up complete car doors, steering wheels or foot mats when only a few centimeters of these products require heat.


Plastics welding and deburring with Infrared heat

Plastic components can be joined by infrared heating without the need for adhesives or other joining mechanisms. The infrared radiation melts a thin surface layer of the individual plastic parts in a short time. The parts are then joined by simply pressing them together to form products such as windscreen washer water or brake fluid reservoirs. In contrast with contact welding using hot plates, no excess material clings to the heat source and heating stage takes place in seconds and is repeatable.
Plastic handles, housing parts, air intakes or covers are often injection moulded. Very often it is impossible to prevent the creation of sharp-edged burrs, especially in the tool separation plane. Shaped infrared emitters precisely melt away only the burr, without damaging the actual work piece.
As a result, they are superior to many conventional methods, such as manual removal with special blades or by the use of gas flames, which do not produce repeatable results and take considerable time.

Our video shows how the deburring of plastic parts can be improved!

Im Focus: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
