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.
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!

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
Laser-driving of semimetals allows creating novel quasiparticle states within condensed matter systems and switching between different states on ultrafast time scales
Studying properties of fundamental particles in condensed matter systems is a promising approach to quantum field theory. Quasiparticles offer the opportunity...
Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).
Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...
