Causes of glass surface damage
In order to avoid glass damaging the surface must be protected during shipment and storage. Appropriate handling and storage techniques maintain the integrity and the transparency of glass. In addition, after installation appropriate precautions and proper maintenance are needed to guarantee long-term performance.

Convection gives the advantage
When new installations of flat tempering machines suited for architectural glass are discussed today, the option of convection technology is certain to be raised. Furnaces based on traditional methods of radiation heating do not meet current market needs, but glass processors want the latest technology that can help boost productivity and improve the quality of production. more »

Digital printing on glass
Packaging, interior design, architecture and other traditional sectors for glass, have often been turned to other media because of the ease and cost-effectiveness with which they could incorporate astonishing visual design directly onto the substrate. Glass had been so far excluded or used sparingly for digital printing because most digital printers could not handle its fragility and weight. more »

Glazing Works at the Tower of the the Erdinger Moos Airport
The Erdinger Moos Airport of Munich, Germany has got a new tower for Terminal 2. Insulating glass panes of 5.0 x 2.3 m made of twice-laminated glass 16 mm thick and weighing about 925 kg had to be installed at a height of up to 45 meters as well as 18 mm thick enamelled special glass plates for the tower facing - and this in the 9° upward-sloping tower. more »

How to handle and store curved glass
Bent glass is simply flat glass which is heated to a specific temperature, at which point the glass softens sufficiently in order for it to be moulded to the required curve. After this final shape is obtained, the handling process differs from that of normal flat glass so as to prevent breakage. more »

Innovations in bending and tempering boost the glass market
The oscillating horizontal tempering furnace developed in the 1970s has been one of the most significant innovations of recent decades, above all commercially. Its success has been based on the inexpensive price of a new machine combined with its versatile usage; a concept that has brought the glass tempering process, giving considerable added value to the end product, within the reach of small and medium-sized companies. In principle it is possible to temper on the same machine automotive and architectural glass, furniture glass and industrial glass etc. more »

Laser glass cutting technology
During the last years, major manufacturers of glass cutting machines have invested more and more resources toward research in the use of lasers for cutting glass. Most of them are convinced that in the next decades, laser-cutting technology will replace the traditional glass cutting method. What does this technology consist of and what are the benefits of using the laser-cutting method? more »

Optical Quality Control: Pre-Processing Of Tempered Glass
The current manufacturing of tempered glass is a complex as well as time- and cost-intensive process. Not only long processing times, but also high energy costs have a significant impact. Additionally, there are often capacity bottlenecks at the tempered glass – as well as at the heat soak furnace. Glass defects and contamination will mean that a high-quality finished product cannot be delivered. Such defects must be avoided at all costs at the beginning of the value creation chain. Some companies try to minimize this problem by using manual inspection at the entrance to the furnace. However, this method is unreliable, since the staff doing the inspection also have to load or unload glass and may not have the right lighting. Furthermore, horizontal glass surfaces are always difficult to examine and when inspections are carried out manually, there is the common problem of limited reliability due to fatigue or low motivation of the staff performing the inspection. An examination location such as this also has the dis-advantage that a glass that has been removed due to defects cannot be replaced immediately, leading to the furnace not being used to full capacity – and, in the worst case scenario, to customers not receiving deliveries on time. A state of the art vision system is today able to cut quality relevant losings with convincing results and even allows the reallocation of human inspectors for other assignments. more »

Rotatable Sputter Targets and Advanced Rotatable Magnetrons
Since their invention in the late 1960s, sputtering electrodes have undergone a development revolution. The most significant technological development has been the discovery and maturity of rotating cylindrical magnetrons and advanced rotating cylindrical sputter targets. These two parallel developments have enabled manufacturers to increase coating throughput and decreased cost of coating, while maintaining the layer quality and thickness consistency. more »

Verre Plat n. 39
À nos lecteurs : La Tribune Libre est, comme son nom l’indique, un espace de totale liberté rédactionelle que VERRE PLAT, depuis su création, offre à toutes vos professions, avec la possibilité d’exposer, sans aucun droit de regard de ma part, les idées qu’ils souhaitent développer.
La trente-huitième Tribune Libre publiée dans notre précédente édition et rédigée par Olivier Douard, Délégué Technique à la FFPV sur le Vitrages Isolants, la norme européenne EN 1279 et la marquage CE n’a pas dérogé à cette règle.
Nous avons reçu, suite à cette Tribune Libre, la réponse de CEKAL, que nous publions bien volontiers ci-dessous. Nous nous réjouissons, à cette occasion, que VERRE PLAT, joue pleinement, au travers de ces deux Tribunes Libres, le rôle qui celui d’une revue professionnelle : exposer les idées, susciter le dialogue et finalement ... informer encore mieux nos lecteurs.
