Plastic tubes and pipes are increasingly being used in civil engineering as well as in domestic technology. Infrared emitters from Heraeus Noblelight help to stress relieve hoses, bend tubes and pipes or form sleeves. They transfer energy in a contact-free manner and generate heat primarily in the material. As a result, heating takes place uniformly and rapidly. This saves energy and space and the heating process can be easily automated.

Heraeus Noblelight is showing infrared heaters for plastics at Fakuma in Friedrichshafen from 14 to 18 October.

Tubes and pipes are used for wastewater, drainage, drinking water and gas or electric cable protection. Plastics such as Polyethylene (PE), polyvinylchloride (PVC) or polypropylene (PP) are increasingly replacing conventional materials such as concrete, stoneware and copper.

Before they are used, plastic tubes are bent into shape, provided with grooves for sealing rings or they have sleeves so that they can be inserted into each other. Conventionally hot air, heating sleeves or hot liquid baths have been used to soften the plastic before forming it. Infrared emitters transfer energy in a contact-free manner and generate heat primarily in the material. As a result heating takes place uniformly and no material sticks to the heat source. The targeted and controllable heat prevents thermal damage or messy pressure points.

Infrared emitters heat targeted areas of a tube or pipe, as the heated length of the emitter can be matched to the bending radius. In contrast to hot air oven, the edge areas remain relatively cool, which permits the component to be simply held, facilitating process automation. Infrared emitters can be precisely matched to the material and process and this saves energy. Because of the high heat transfer capacity of infrared radiation, heating times can also be reduced, which means production is faster or valuable production space is saved. Trials in our in-house Applications Centre have shown that a few minutes infrared radiation are sufficient to warm through PVC tubes with a wall thickness of more than 20 mm.

Conventionally, the sleeving of tubes takes place with the aid of heating jackets, which transfer heat into the plastic through close contact. Shortwave Omega emitters are circular and can heat small sections in a targeted manner. Omega emitters or small flat emitters arranged in a circle heat the tube ends without contact to make the plastic there soft, so that a sleeve socket can be formed.

Shortwave infrared emitters have response times in terms of seconds so that they can be easily controlled. They transfer heat rapidly at high efficiency. Infrared emitters need be switched on only when energy is needed and this is another energy-saving feature.

As well as shortwave emitters, Heraeus Noblelight also offers Carbon infrared emitters with a spectrum which is particularly well matched to the absorption characteristics of plastics. Carbon infrared emitters combine highly effective medium wave radiation with the short response times of shortwave emitters.

Common to all Heraeus emitters is the way they can be matched to the relevant process in terms of shape, size and spectrum. As a result, complex heating stages can be reproduced and automation can be introduced.

Heraeus Noblelight offers the complete spectrum of infrared heat from very shortwave NIR to medium wave Carbon Infrared (CIR). Heraeus has more than 40 years experience in infrared emitters and carries out practical tests with customers’ own materials in its own in-house Application Centres, to determine optimum process solutions.

Im Focus: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".
