Heating Glass With IR
Glass manufacturing processes can benefit greatly from infrared technology. The efficient and heat-just-where-it's-needed
qualities of infrared make it an excellent method of supplying heat to glass processes. For example:
- A manufacturer of flat glass needed a process to preheat glass before it entered the coating step (performed in vacuum). A
stianless steel oven suffered from slow heating, and the cumbersome unit took up valuable plant space. A pair of carbon infrared
modules from Heraeus Noblelight provided fast heating, low energy consumption and a small footprint.
- A plant manufacturing CRTs (cathode ray tubes) sought a preheating method for its process. Modules containing shortwave
heaters from Heraeus Noblelight provided precise heating, and the process helped minimize bulb breakage.
- A safety glass manufacturer had been using longwave lamps to heat the laminate on its product. That method suffered from
low efficiency, short lamp lifetime and mismatched and imprecise heat wavelength. Heraeus engineers provided a solution that
included mediumwave twin tube infrared lamps. Quality improved, efficiency increased, lamp lifetime was extended, and the
process line speed was greatly increased.
- A glass manufacturer sought a replacement for its hot air heating system. The application involved heating car window glass
to improve the adherence of PU foam on the black enges. Fast mediumwave infrared heaters from Heraeus provided that improved
foam adherence while allowing a wide variety of window sizes to be processed in a single oven. Scrap was eliminated, affording
a production increase of 10%.
