Metrology - good data means better results

Float glass production

As a glass manufacturer, a stable production process is more important than ever these days. Grenzebach’s inspection and measurement procedures stand for advanced control methods and top product quality.

Good data means better results

The data captured are fed back into the production process. They help spot departures from processes at an early stage and trend analyses of recurring problems reduce losses. The production process is fully transparent and full complete product analysis is possible.

The following aspects are measured in real time:

Contours and sizes
Edges
Position of the glass ribbon
Thickness of glass and layers
Stresses
Temperature
Quality
Surface quality

Data from the complete production line

CNUD EFCO GFT and Grenzebach’s integrated approach permits analyses to be made and conclusions drawn about the whole production process. And customers have the benefit of faster response times with minimal use of resources.

Example number one

Ribbon thickness is measured directly at the beginning of the annealing lehr to allow a faster response should production differ from the thickness tolerances permitted.

Example number two

At the cold end, Grenzebach measures the glass ribbon’s stress profile, in other words, the stresses that occur within the glass along a measurement line across the glass ribbon, which generate during the cooling process. Thanks to Grenzebach’s SERICY IIoT platform, the settings in the annealing lehr can be changed in order to reduce stress peaks.

Product Traceability

Staying on track

If an item of glass in a high-rise facade needs replacing, then product traceability is invaluable. All the information and data generated along the value chain can be captured and used. The ability to associate this information with basic sheets of glass and the products these are turned into allows stakeholders in the glass ecosystem to trace the whole process, starting from the production line to the warehouse and all the way to the consumer. This is a huge asset and the foundation for continual improvement.

Product Traceability

Partnership and service that go the extra mile.

Our service for the glass industry

We Service

Technology & equipment

Float glass production

Tin bath

The tin bath is the heart of every float glass production line; it is a decisive quality factor. Consequently, at CNUD EFCO GFT, it is always tailored to each customer’s requirements. Using process simulation, we are able to extract the ultimate in yield and quality.

Annealing lehr

The annealing process is a decisive factor for quality, productivity, and efficiency. With our innovative systems, you can keep it fully under control: the latest technological control applications monitor your process at all times, prevent production losses and help to minimize downtime.

Waste heat recovery systems

Environment protection and economic efficiency can go hand in hand if the right solutions are used. With our innovative systems for waste heat recovery, you can make your glass production more energy-efficient and at the same time create a new source of energy for your company.

Utilities and central power supply

For a float glass plant to operate reliably and at peak performance, it needs a steady supply of energy and other media like natural gas, electricity, inert gas, tin and much more.

Conveying technology

Our technology conveys glass gently and precisely – even over distances greater than 100 meters or 110 yards. What’s more, our conveying solutions operate smoothly and have long service lives too.

Cutting technology

Cutting technology lies at the heart of the cold end of a float glass production line. Combined with the breaking system, the cutting heads, force-regulated controls and an intelligent optimization system form a superbly efficient unit.

Metrology

As a glass manufacturer, a stable production process is more important than ever these days. Grenzebach’s inspection and measurement procedures stand for advanced control methods and top product quality.

Stacking tin air speed stacker Grenzebach

Stacking technology

For the glass line’s stacking process to work well, it relies on a good sorting process. We can develop a smart system for you so that conveying and stacking are a class act.

Coating technology

Architectural glass showcases buildings. Grenzebach’s PVD coating technology turns the raw material into an energy-efficient component. PVD large-area glass coating is a core technology that meets requirements in terms of functionality and appearance.

Digitalization

Digitalization is opening the door to a spectacular future of glass production. Be a part of the journey with our digitalization solution for tomorrow’s glass production.
