New industrial glass processing technologies have been developed by Gyrotron Technology Inc. that are significantly more efficient and productive than any common existing heat processes using hot gas, electric resistances, or industrial microwave. The developed industrial glass processing technologies are based on using the gyrotron beam that possesses unique properties and allows incredible results.

The gyrotron generates a microwave beam from a few KW up to one megawatt power. By simple metal mirrors the beam can be focused, spread over a surface, directed — all with superior heat density where it’s focused and no heat where it’s not as well as with controllable uniformity.

The gyrotron beam glass processing technologies open a new mode for heat processing glass that results in significant reduction in capital and operating costs, as well as increased product quality and the possibility of new types of glass products. Here are some examples of where this beam can be used.
Heating glass sheets for shaping/bending
Heating fast means eliminating the need for tunnel furnaces, dramatically reducing ...
... capital and operating costs and space consumption. Besides the ability to control power distribution over the glass sheet, heating at the bending site and heating of bending tools, it facilitates manufacturing automotive glazing of superior quality, new designs and complex geometries.

Tempering thin glass
The gyrotron beam provides an exclusive, controllable temperature distribution inside the glass sheet in the whole temperature range that is appropriate for processes where increasing and reducing glass temperature is desired. Annealing or tempering can be accomplished when a cooling gas agent such as cold air is applied to the outer glass surfaces. By selecting a microwave radiation with a wavelength equal to about two times the thickness of the glass being treated, it is possible to achieve virtually any temperature differential between the outer glass surfaces and any layers inside the glass sheet during temperature reduction. As a result glass thinner than 2mm can be fully tempered.
Sealing glass
The gyrotron beam can be targeted exclusively on a seal through the glass sheet, processing it rapidly, without heating the entire product.
The ability to heat fast and locally also allows joining tempered glass sheets without loss of temper. Despite the comparatively high processing temperature of commonly used frits, above 400C and sometimes up to 500C, the post-processing level of temper remains high (above 80% even in the processing area) because processing time is very short, less than 10 seconds. Glass outside the processing area remains practically at it’s original temper level.
Processing fiberglass-based composites
Selective controllable heating of composite components to different temperatures is possible with the gyrotron beam. This allows the optimal fiberglass temperature to be maintained during the curing process, resulting in an ultra-rapid, effective process.

The gyrotron beam installations for these new industrial glass processing technologies have a small foot print and can easily be installed into existing lines with little shutdown time. The gyrotron beam seems the twenty first century’s new tool for glass processing. With it’s range of previously-unavailable capabilities, the benefits can be applied in diverse processing environments to increase throughout and speed, enhance product quality, and engender new product designs. Many industries can benefit by using these new industrial glass processing technologies.
