Keraglass Spherical and Cylindrical Bending Furnace

Imagine a curved furnace capable of anything. Now stop imagining.

The world of glass processing is constantly evolving, and Keraglass has always been at the forefront of this transformation. Tempered curved glass, in particular, is now one of the most in-demand solutions across various industrial sectors: from automotive to architecture, from home appliances to interior design.

To meet market demands, Keraglass offers Visionbend, a bending and tempering furnace capable of processing flat glass, cylindrical curved glass, and spherical curved glass with maximum flexibility and consistent quality. This system integrates two advanced forming technologies, ensuring precision, reliability, and industrial repeatability.

With over 30 years of experience in glass bending and tempering processes, Keraglass continuously works to refine and optimize each stage of production, delivering precise results aligned with the needs of modern industry.

Advanced Forming Technology

The core of the system consists of two complementary technological solutions:

K-PRESS – Precision Spherical Bending
K-PRESS technology is based on a continuous ring system that combines mold and press to achieve precise and stable spherical curvatures. The off-set tempering layout and configurable hood system allow for excellent optical quality and flawless geometry, even with thin glass thicknesses.

K-ROLL – High-Productivity Cylindrical Bending
For cylindrical bending, K-ROLL uses a bending roller system capable of ensuring high-quality standards and continuous productivity. Keraglass has innovated the traditional design, creating a unique system that is reliable, precise, and ensures consistent repeatability of each piece.

Flexible Configurations

The system can be configured according to production needs:

• Unidirectional, by selecting one of the two technologies
• Bidirectional, by integrating both technologies within the same furnace, sharing the same heating and ventilation area

This complete versatility also allows for flat glass processing, meeting the production needs of multiple industries.

One Furnace, Endless Possibilities

The Keraglass bending system enables the production of a wide range of geometries:

• Cylindrical and multi-radius curved glass
• Spherical and deep spherical curved glass
• J-shaped and complex curved glass, with no radius limitations
• Tempered flat glass

Thanks to the 500°C convection system, it is also possible to process LOW-E glass with emissivity as low as 0.01, ensuring high performance even with the most delicate materials.

Unlimited Applications

Curved glass opens up creative and functional possibilities across numerous sectors:

• Automotive, where precision and safety are essential
• Shower enclosures with elegant, modern design
• Home appliances with contemporary and functional lines
• Display refrigeration units combining aesthetics and performance
• Architecture and interior design for iconic projects

Aesthetics and Custom Design

Curved glass is not only functional—it is also a design element. It enables the creation of dynamic, lightweight, and contemporary spaces, adapting to non-linear shapes while always ensuring top-level quality, aesthetics, and performance.
