Infrared Emitters at the Fakuma Exhibition in Friedrichshafen, 2009

16.07.2009
Targeted Infrared Heat – The Next Generation
QRC® Infrared Emitters with Nano Reflectors for Edges, Corners and Burrs
  • Infrared emitters transfer heat without contact
  • New QRC® emitters with nano reflectors improves automated heating processes in restricted work spaces
  • Infrared emitters from Heraeus Noblelight on show at Fakuma in Hall B1, stand 1121 from 13th to 17th October.

High value plastic parts require careful processing. Burrs must be removed, joints must hold seamlessly and securely. Infrared emitters apply heat in a contact-free and targeted manner to edges, corners and seams and melt away mould release burrs without causing damage to the product.

At Fakuma in Friedrichshafen, Heraeus Noblelight is showing QRC® infrared emitters, which can be matched to shapes of work pieces for processes such as deburring, welding or the activation of adhesives. The new QRC® emitters (QRC = quartz reflective coating) have a nano reflector of quartz material and can be constructed to match exactly the shape of the work piece. This also makes difficult heating processes energy-efficient and capable of being automated. Stable heating processes ensure constant high quality over a very long period and reduce reject rates significantly.

Mobile phone casings, radio bezels and the internal fitments of cars are made of plastics, which are often laminated, galvanized or coated in a metal- or wood-effect lacquer after injection moulding. Burrs, which can ensue at the parting plane of the mould tool, must be removed or rounded off. They not only look unsightly, they also affect the coating process and can cause any subsequent coating to peel off.

Particularly with parts of complicated shape, the removal of burrs on the component edges can be a very real requirement. Infrared radiation heats plastic components without contact, in seconds and is targeted at the surface, so that burrs are simply melted away.

Moreover, infrared emitters of quartz glass can be shaped to match the edges or burrs, so that they heat the burr exactly and in a reproducible manner without damaging the actual work piece. Consequently, infrared emitters are superior to conventional methods such as knives or even open flames. Moreover, a highly developed heat source which ensures that heating processes are carried out at a constant quality over a long period is beneficial. The newly developed QRC® emitters with nano reflectors are impervious to vapours, outgassing and high temperatures. Consequently, they are ideally suited for de-burring plastic components immediately after they are removed.

“The new QRC emitters with nano reflectors are the next generation for targeted heating in plastics processing!” says Rolf Diehl, manager of the Industrial Process Technology Division at Heraeus Noblelight. “We can see that heating processes are stabilized with nano reflectors and that increases the energy efficiency of equipment.”

The nano reflector is very durable and ensures consistent quality over long periods.

Opaque Quartz Glass Sets the Standards.
The newly developed QRC® emitter now makes it even easier to work in confined spaces. The ambient temperature roses in confined spaces and not every heat source can withstand such high temperatures, vapours or outgassings. This is precisely why the QRC® reflector was developed at Heraeus Noblelight. It directs the heat onto the material in a targeted manner and also maintains its good reflectivity even when used for long periods in difficult environments.

With infrared emitters fitted with the new QRC® reflector the reflector is not made of gold or metal oxides but of opaque quartz glass. Quartz glass is extremely heat-resistant and broadly resistant to the attacks of acids, alkalis and other aggressive substances. Thanks to the very highly diffuse reflection capability of the emitter with the white reflector, heating processes can be stabilized and optimized, as process parameters such as temperature and coating homogeneity can be held better. This lowers costs and increases plant energy efficiency.

Targeted Infrared Heat
Infrared emitters are matched exactly to the production process, they heat large surfaces just as well as small edges. Flexible design and construction allows them to be used on work pieces of complex shapes and because infrared emitters are switched on and off in a matter of seconds, there are significant savings in energy and process costs.

Heraeus Noblelight offers the complete spectrum of infrared heat from extremely short wave NIR to medium wave carbon infrared CIR®, carries out tests with the relevant materials and advises on the choice of optimum emitter for a particular process.

Heraeus has more than 40 years experience with infrared emitters and carries out practical tests with customer own materials in its own application centres to establish optimum process solutions.

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: RAVAN CubeSat measures Earth's outgoing energy

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
