Infrared Heat for Glass and Ceramics Processing Applications

Drying screen print on car windows, cutting laminated glass or coating mirrors - many stages in glass processing need heat. In an increasing number of cases, infrared heating technology offers an excellent solution to heating challenges!

IR heat for glass and ceramics processing

With the right infrared emitter, you can direct heat exclusively to the foil inside laminated glass without heating the entire pane. Infrared emitters are also ideal for tempering as they can be controlled accurately to enable precise temperature profiles.

Your advantages with infrared heat:

  • Medium-wave infrared radiation is optimal for the absorption of glass
  • Gold reflector on the emitters directs the heat precisely to the part of the product which is to be heated
  • Infrared emitters are precisely adjusted to the material and process, which saves time, energy and costs.

After forming, glass develops stresses during cooling. These stresses can cause shattering during subsequent processing. To remove stress (and to reduce scrap), glass is subjected to an annealing process at a controlled temperature profile. Infrared heaters are ideally suited for this process because of their high degree of control. An annealing tunnel with infrared modules can be individually regulated with a fast response to effectively produce maintenance-free products such as incandescent bulbs and energy-saving lamps in an energy efficient way.

In the production of thin film solar cells, float glass sheets are heated prior to coating. This process requires a vacuum situation. Infrared lamps, which generate heat directly in the vacuum space, can heat the float glass very effectively. Heraeus can modify specific lamps for operation in vacuum by means of special sockets and leads with special voltages as required.

MAX Infrared Oven allows Fast and Homogenous Glass Tempering

Infrared is tempering glas

Heraeus Noblelight was able to heat glass five times faster and reduce energy consumption by 90% with the help of the newly developed MAX infrared oven. The tempering process time can be reduced, energy efficiency increased and operating costs lowered.

Infrared Heat helps Cutting Laminated Glass

IR is cutting laminated glass

The manufacture and processing of laminated glass requires a few heating stages, which can be accomplished very well with infrared emitters.

Medium-wave heaters are an optimal solution for drying screen printing on glass for the black borders. Although both reliable and durable, medium wave heaters are slow and not particularly powerful. Heraeus Noblelight’s carbon infrared heater CIR® combines the effectiveness of medium-wave heaters with high performance and rapid response times.
