Bird protection glass made by laser printing

The "laser upgrade" to bird protection glass helps to minimize the problem of bird strikes. A wafer-thin pattern can be applied to the outside of the facade glass, which birds perceive as a clear obstacle. In Europe alone, 250,000 birds die every day from hitting a window. Internationally, new legal regulations are creating a large sales market, and the demand for glasses with a bird protection function is also increasing in many local markets in public or commercial buildings.

Optimization – A key to save energy!

Fabrication of flat glass requires a large amount of energy resulting in a heavy carbon dioxide footprint. Waste is not just a waste of material and money, it is adding visibly to this footprint. Hence, one of the main goals in processing flat glass has to be avoiding waste wherever possible. This generates the need for cutting optimization which itself depends very much on organization and product portfolio. Related state of the art techniques will be presented.

The laser revolution in glass processing, is it just around the corner?

Lasers were used for years in glass processing applications such as marking, engraving, drilling, de-coating and cutting display glass. Yet, the larger adoption of lasers in bulk processing of float glass is still to emerge. Meanwhile, the laser technology can potentially bring the industry’s resource efficiency to a completely new level. This presentation provides an overview of the latest developments in laser applications and explains differences between different types of lasers.

Glass in active building facades

To achieve climate targets enormous areas for PV systems are needed. Currently, facades are hardly used for solar applications, but they can make a significant contribution, far more than roof surfaces. A new type of color technology in the front glass, installed in powerful PV modules, opens up new design possibilities. The technology meets the high aesthetic requirements of a glass facade and combines this with the generation of electrical energy in activated building envelopes - all in color.

Precision laser cutting of glass for industrial applications - Elimination of water, slurry, time, energy, with higher utilization of glass material

Demand of fast cutting solutions for complex shapes on transparent & brittle materials in consumer electronics, automotive & semicon industry can be addressed by laser cutting technology. Our nanoperforation process induces localized material modification rather than material removal, resulting in high-quality laser cuts. Post processing steps can be reduced & usage of water, slurry, time, energy become obvious. Freeform laser cutting improves material utilization by freely chosen part position.

VDMA - Digitalization in glass machinery manufacturing (OPC UA)

Chair: Gesine Bergmann


How Réné Magritte inspired the Asset Admin Shell

More and more digital information about products, no matter if machine or glass product are available and required. They range from technical parameters, via nameplate, utilization, and cleaning manuals up to detailed engineering documentation. For administration and information transfer, this calls for a systematic structuring at best in a standard universally accessible. We would like to show you how the Rene Magritte laid bases for creating such interoperability standard now called Asset Administration Shell and show on practical example how it helps saving time and money.

A solid base to build-upon: OPC UA Machinery

In the VDMA, more than 40 working groups with over 600 companies are working on the creation and publication of OPC UA interface definitions. Some of the information to be defined is not only relevant for a specific machine type or industry, but for the entire mechanical engineering sector. These are represented in OPC UA for Machinery. This talk will explain why OPC UA for Machinery serves as a basic specification and provides the perfect entry point for new machine interfaces.

The base specification for all interfaces on glass processing: the OPC UA CS 40301

The development of interfaces is not new. But, for the very first time many manufacturers harmonize the procedures handled by interfaces in the glass processing industry. The effort during implementation of the machine and the preparation of the production will be much lower in the future. If you can use the same structure for sharing and providing data with all machines in your production line, you can overcome the diversity of interfaces in different languages of the suppliers. This is a major step to Plug and Produce. The presentation will give an introduction and brief overview of the details specified in the following presentations on recipe, machine monitoring and the demonstration tool.

How does VDMA help the glass industry out of interface troubles? 2/3

Let´s make detailed order transmission simple: The Recipe Specification VDMA 24124

To process a job, a machine has to be aware of all the details that define that job. Typically up until now the recipe management sitting on the machine is mapping the material and processing codes supplied by the MES system to something that is known to the machine. Using our new recipe definition, the responsibility for this mapping is fully taken away from machinery suppliers! This way opening doors for seamless integration of different machinery as well as software vendors!

How to get standardized data back?
After having successfully standardized the OPC UA communication of jobs, we are now focusing on the standardization of machine feedback, to calculate production KPIs such as the OEE.Norms like the ISO 22400 define, how production times as well as resulting KPIs are calculated in a comparable manner and in return have specific requirements on the machine feedback received.Within our presentation we would like to show the status we achieved and the promising outlook, from which any flat glass production may benefit from.

Electrical Glass melting and boosting solutions of the future designed for efficiency, flexibility and Demand Side response

With a target to dramatically reduce CO2 by 2050, electrification of glass furnace is the most technologically ready to help the industry to transition from fuel and to reach the target. We expect the size of SCR based electric glass melting systems to grow especially for container and eventually also for flat glass furnaces. We believe flexibility and granularity of control will be key to the operation of those furnaces and to implement demand side response strategy to reduce cost of energy.

Chances and limitations of full electric melting furnaces – Concepts for the further development of Sorg’s VSM(R)

Company Nikolaus Sorg GmbH & Co KG is one of the world’s leading suppliers of customized solutions for glass melting furnaces and conditioning systems and supports its customers in meeting the challenges associated with the socially desired energy transition. The technology of all-electric cold-top melting , as known from Sorgs VSM(R), has a firm place in the glass industry due to the high glass quality as well as the energy efficiency worth seeing. Beside that the cold-top technology offers an additional advantage due to the function of the cold batch cover as a condensate trap, when aggressive raw materials are used, such as in opal glass production. While the energy efficiency and glass quality of these systems are very attractive, their application today is limited by a maximum tonnage of approximately 200 tons per day. Nevertheless the VSM(R) offers a unique combination of different advantages, such as the closed, almost dust-free, rotating superstructure, the use of easy-to handle top-electrodes and the compact design. The presentation will discuss interesting opportunities as well as limitations of all-electric glass melting furnaces and outline surprising solutions for future developments.

Smart window films for heat and light management in buildings

Solar heat through glazing causes overheating of buildings. Therefore, there is an increasing energy demand for artificial cooling of indoor spaces. In this work we develop smart window films that autonomously control solar heat and daylight transmission through glazing based on changes in outdoor weather conditions. Besides color-neutral, also films with special reflective colors can be prepared. The films can be adhered to existing glazing and thus provide a cost-effective renovation solution.

Development of Optimal Structures of Cover Glass for Improved Efficiency in Solar Modules

Structures in glass improve light coupling into the module and internal light management through enhanced internal reflection. We study the influence of structured backside glass for bifacial modules on module power output and theoretical structure adapted to realistic production conditions by implementing roundings. These results are compared to modules with conventional white polymer backsheet. We show, structured glass can replace backsheets without greatly affecting internal reflection gain.

Mechanical strength testing and evaluation of thin large-format solar glasses

Larger wafer formats are being introduced in the solar industry, resulting in larger module dimensions of up to 2.3 x 1.3 m². Glass strength under high loads (storm, snow load) is an important quality assurance issue. In this paper, a test setup for strength testing of large-sized 2 mm panes is presented. Due to the geometric nonlinearity, the evaluation must be supported by a finite element simulation to determine the fracture stresses.

Design and durability of cold-bent insulated glass units

Curved and free-form façades including the use of insulating glass units (IGUs) represent a clear trend in architectural design. Hot bending is the most common technique used to produce curved IGUs. Although its effectiveness has been proved in many projects, it is well known that it can be very expensive due to the big amount of moulds usually required to build up a free-form façade.As alternative to the ‘hot-bending’ technique, the increasingly used ‘cold-bending’ method is investigated in this paper being less expensive as well as more sustainable. Such method consists in imposing an out-of-plane displacement to flat insulating glass units and generally requires forces of limited magnitude applied on site during installation.Cold-bending introduces permanent loads into the glass panes, the glass interlayers, the secondary sealing as well as the primary sealing, the latter one responsible for the gas retention and the resistance to moisture penetration in the IGU cavity. Focusing on both integrity and durability performance, the paper presents the results of FEM analysis as well as tests performed on double glazed units including Sikasil® IG-25 secondary sealing joints and SikaGlaze® IG-5 PIB as primary seal and investigates their behavior due to cold-bending and exposure to climate conditions in accordance with EN1279-2. The limit identified is applied for the design of cold-bent IGUs in a high-rise building facade.

Facing up to global challenges through the application of microstructures in glazing

The global building industry is changing due to enhanced building directives and an increased focus on CO2 emissions and indoor climate. For years, the innovation has been aimed towards controlling the amount of energy from the sun that enters a building. However, as these requirements often exceed what conventional glass coating solutions can deliver, the industry has had to adopt to expensive external shading systems and double facades. The challenge with conventional shading systems is, that while they are effective in providing solar shading, they also reduce the daylight intake and the view to the outside. In addition, the conventional shading systems are expensive, complex to install and operate and have limited lifetime expectancy. Therefore, new approaches need to be invented. Solutions that provide effective shading, while maintaining the natural daylight and the view to the outside. At MicroShade we have found that all of these needs can be addressed through the application of microstructures inside the glazing.
