	Bending and tempering of architectural glass goes horizontal During the past 15 years tempering of bent glass has mainly changed to horizontal methods. Large series for the automotive and furniture industries are today made almost without exception on horizontal tempering machines. Smaller runs for special vehicle manufacturers and the construction industry are still made on older, vertical machines, but with developments in batch bending and tempering technology, these sectors are also increasingly switching to horizontal tempering. Tempering that uses a glass bending furnace gives unbeatable advantages in the production of large pieces of architectural glass with high optical quality requirements. more »

At the time, other manufacturing processes could not provide a perfectly-flat result. more »
	Forehearth operation - making it easier, making it better Part 1 – add-on systems Forehearth operation is simple – you just set the temperatures you need on the zone controllers and away you go. In fact, it is so easy that the production department can attend to it alongside their real job of running the machine. Sometimes it may be this easy, but increasingly often this is far from the truth. As forehearth complexity increases to give better results, their operation also becomes more complicated, requiring more time and/or specialist knowledge to achieve the required results. However, there are some additional systems specifically designed to improve and/or simplify forehearth operation. Part 1 of this article looks at some of these. more »

	Traditional but challenging Bent Tempered Glazing Benefits of the tempered glazing are well known and the tempered glazing is being utilized more and more in many different applications. Manufacturing technology in this area of safety glazing is developing fast. However traditional gravity bent tempered processing still exists and new bending & tempering machinery is being developed for this processing method. Most important benefits of this tempering method based on the forming by gravity bending are smaller investments and tooling costs and ability to produce small series. However two-way bent tempered glazing produced with gravity bending is one of the most challenging forming processes in the safety glass industry when it comes manufacturing furniture, architectural, special vehicle, automotive or marine glazing. General principles between gravity bending (bent laminated glasses) and gravity bent tempered processes are quite similar, but producing bent tempered glazing using gravity bending method can be especially challenging. Sag and shape of the glass are frequently the biggest challenges producing any gravity bent glazing, but with bent tempered glazing number of critical challenges/factors increase significantly. This article will review the challenges processing bent tempered glazing. more »
