Paint on Plastic Dries More Quickly with Infrared Emitters

11.01.2008
Modern cars, computers and electronic equipment contain components, which are printed and then coated with a protective or a metallised lacquer.

Conventionally, these lacquers and coatings are dried or cured by means of hot air. Increasingly, the market requires faster production speeds, which, in many cases, can be achieved by means of infrared drying. A British manufacturer of key boards and keypads is drying its protective lacquer coatings in less than four minutes using infrared, compared with the previous 20minutes required by a hot air oven.

Heraeus Noblelight will be showing emitters for lacquer drying on stand 3541, Hall 3, at PaintExpo in Karlsruhe.

Kestrel Injection Moulders in Great Britain produces keyboards and keypads for cars or for use in electronic equipment, computers or white goods. These pads are injection moulded plastic products and need to be printed and coated with a protective clear lacquer. Previously, the components had to be dried for around 20 minutes in a hot air oven. During this extended period, dust could settle on the product to adversely affect the quality.

An infrared oven from Heraeus Noblelight is now drying and curing the coatings on the keypads in less than 20% of the time required by the convection ovens.

With its 1.5m length and 1m height, the infrared oven fitted easily into the available space. It consists of two modules, each of 3 kW output and is fitted with medium wave infrared emitters, which in pre-installation trials had proved themselves as a successful and faster alternative to hot air.

Currently, the new ovens handle two different types of keypads. One type is coated with a water-based lacquer after manufacture, is pre-dried, printed and then finished with a clear protective lacquer. Other keypads do not require a pre-coating and can be immediately printed and coated with the protective lacquer.

Since the installation of the infrared ovens, the rejection rates have been significantly reduced. Naturally, this enormously reduces the time in which dust can fall on the keypad surfaces. In addition, the infrared system has also proved itself to be extremely energy-saving, as, in contrast to the convection ovens, it needs to be switched on only when heating is required.

Heraeus Noblelight offers a comprehensive range of infrared emitters to heat plastics, lacquers or coatings rapidly and efficiently. Infrared ovens are so compact that they can be easily retrofitted into existing production systems and layouts. This saves space, time and cost.

Heraeus Noblelight GmbH with its headquarters in Hanau and with subsidiaries in the USA, Great Britain, France, China, Australia and Puerto Rico, is one of the technology- and market-leaders in the production of specialist light sources. In 2006, Heraeus Noblelight had an annual turnover of 88 Million € and employed 651 people worldwide. The organisation develops, manufactures and markets infrared and ultraviolet emitters for applications in industrial manufacture, environmental protection, medicine and cosmetics, research, development and analytical laboratories.

Heraeus, the precious metals and technology group headquartered in Hanau, Germany, is a global, private company in the business segments of precious metals, sensors, dental and medical products, quartz glass and specialty lighting sources. With revenues of more than EUR 10 billion and more than 11,000 employees in over 100 companies, Heraeus has stood out for more than 155 years as one of the world’s leading companies involved in precious metals and materials technology.

Im Focus: Electron highway inside crystal

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.

Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...

Im Focus: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
