Infrared heaters dry coating or printing efficiently

Infrared heaters dry coating or printing efficiently

Infrared technology has been used for many years in the industrial manufacturing sector. It is relatively recently that this technology has been used in medical technology. However, for some time, infrared emitters have been used directly used to heat tissue before liposuction and they help to remove wrinkles. Infrared emitters are used indirectly in processing medical goods, such as drying granulates, vulcanising tubes or activating adhesives on plasters.
Infrared emitters from Heraeus Noblelight transfer heat without contact and are easy to control. As a result, they can be precisely used in sensitive processes and in clean rooms.
It is already well known that infrared heat dries coatings and heats plastics. And many people still remember the old infrared lamps in bathrooms and in piglet rearing. But applications in medical technology?
Modern infrared emitters offer much more than simply heat. Above all, they transfer energy very precisely and according to the properties of the product and the requirements of the production activity. Modern infrared emitters can be matched exactly to the heating process in terms of wavelength, shape and power and they react to control commands in a matter of seconds. As a result, temperature profiling is possible and difficult process conditions can be precisely adhered to.
A very big advantage of infrared technology is that the energy is transferred by electro-magnetic radiation so that the heat is first generated in the product itself and there is no need for a contact/heat transfer medium such as air or gas. This minimises contamination and facilitates heating applications in clean rooms or under vacuum.
Infrared radiation is already being used directly in the healing of skin complaints, where the skin must be irradiated with radiation of quite precise wavelength. Likewise, creases or skin folds can be removed with specific short wave emitters. Good results are also being achieved in liposuction. Medium wave carbon emitters are used to warm the body fat before it is actually sucked away, providing significantly better results.
Infrared emitters are being used even more increasingly in medical technology in indirect applications. Infrared heat offers contact-free welding of filters and is more cost-effective than ultrasonic welding. Infrared heat also dries coatings or printed lettering on syringes, tubes, bottles or other containers and is used to shrink foil onto tubes. Elastic bandages, gauze, powder and granulates are also efficiently dried and unwanted burrs on injection-moulded plastic materials can be easily melted away and removed.
Another advantage of infrared is that edges, corners and very small areas can be heated in a targeted manner, while the rest of the product or production plant remains comparatively cool. Quartz glass emitters can even be made so that they meet three-dimensional heating requirements.
In contrast to hot air, infrared heat has a very high heat transfer capacity. This speeds up heating processes so that either product through-put can be increased or the oven can be reduced in length.
Heraeus Noblelight offers infrared emitters matched to product and process. More importantly, they also offer customers the opportunity to carry out practical tests on sensitive processes in their own in-house Applications Centre. Tests are carried out by technicians and application specialists and are evaluated, with computer support, with the customer.

An infrared heating system from Heraeus Noblelight is helping to ensure the high quality of composite aerospace structures manufactured at the new GKN Aerospace facility at Western Approach, near Bristol. The system, which is used to provide interim processing of the laid-up composite rear spar assembly of the Airbus 350 XWB to prevent subsequent wrinkling, was custom-designed and developed in close co-operation with GKN Aerospace engineers following initial tests at
Seven Good Reasons for the D2plus Light module
Heraeus Noblelight, one of the technology and market leaders in the field of specialty light sources will again exhibit at ANALYTICA, to be held in Munich, Germany in April 2012. Heraeus will introduce its “Seven Good Reasons for D2plus Light modules” at the show, making the life of instrument developers easier. Developing new analytical instruments places ever-increasing demands on engineers, to design-in the best available light-source and avoid future operational problems.
Specialty Light Sources for the Printing Industry
Hanau, February 2012 The Competence in Specialty Light Sources for printing systems Special and personalized printing processes need special treatment. The ink of ink jet or laser printers need to be completely dried or cured before the printed sheets are passed on for subsequent operations such as stacking, cutting, folding or gluing. Infrared or UV technology is used for drying and curing, depending on the type of ink. Heraeus Noblelight presents its
Infrared Emitters Improve Lacquered Surfaces
Many screens, internal claddings in cars and high value cosmetic packages are manufactured from plastics and contain a protective lacquer or finishing. The drying of the coating on the plastic components is not a trivial matter, for the surfaces need to be perfectly cured without applying to much heat to the plastic. Infrared heaters transfer energy in a contact-free manner and are easy to control. Consequently, the heat is precisely
