Grenzebach Maschinenbau GmbH products

Now more than ever, glass manufacturers rely on a stable production process. Grenzebach`s optical inspection and measuring process stands for state-of-the art production control systems paired with maximum product quality.

We are transporting glass gently and safely - even over long distances exceeding 100 meters. Grenzebach`s conveyor technology stands for efficiency, precision, smooth operation and long life spans. We have successfully implemented special solutions, such as cleaning devices of the bearing races, non-contact alignment or special glass widths up to 6 meters.

The cutting technology sits at the core of the cold end of a float glass production line. Highest cutting accuracy and availability are just two of the many standards Grenzebach relies on. Longitudinal and transverse cutters are equipped with field-tested Grenzebach cutting heads. The electromagnetic cutting force controller allows for accurate adjustment of the cutting pressure which can be fine-tuned with newly developed controls. The cutting technology achieves its highest level of functionality in combination with the surveillance camera Float Scan Edge and the "look-ahead" cutting optimization -granting highest precision, quality and performance.

Defects in the glass ribbon from inclusions, bubbles or stones force the glass manufacturers to dispose off the defective glass in the trough. So far, the shortest cullet plate, depending on the division of rollers, is at least 500 mm long. With the system, `short cullet plate` of Grenzebach the speed can be reduced down to 170 mm. This is possible because the trough strip is disposed of immediately after the snapping roller. This Grenzebach technology improves the glass yield by up to 2%.

For precise stacking at the end of the glass line, Grenzebach offers high quality technologies: from simple manual removal to a fully-automated stacking for small, medium, jumbo and jumbo XXL sizes for up to 3 tons. These include:

We are the world`s only supplier of complete customised coating solutions, all under one roof. We do not only provide the complete PVD coater and loading / unloading equipment, but also the related quality inspection equipment.

Worldwide, more than 40 Grenzebach thin film lines have been installed for CIGS and CdTe technologies. Our portfolio ranges from conveyance and buffering technology to in-house developed MES systems.

Calcining PlantThe plants developed by Grenzebach for the calcination of natural gypsum and synthetic gypsum have set international standards in the gypsum industry.

Gypsum plasterboard manufacturers get the complete range at Grenzebach. Our technologically advanced plants are characterised by a high degree of automation and performance that are in keeping with the customer`s requirements.
