What temperature control challenges do ceramic kiln manufacturers face?

Ceramic and glass production are processes where precision plays a key role, and temperature control is one of the most important elements determining the final quality of the products. In kilns, where temperatures can reach as high as 1,300°C, every degree matters. Even a slight deviation from the planned heat profile can lead to serious problems - cracks, uneven glazing and even the complete destruction of products. That's why furnace manufacturers like Rohde face enormous challenges to ensure stability and precision in these complex processes. Effective temperature control not only affects product quality, but also production efficiency, process repeatability and compliance with quality requirements. Lack of an adequate control system can result not only in financial losses, but also in a loss of customer confidence.

Why is precise temperature control crucial in ceramic and glass production?

Precise temperature control is the foundation on which the entire ceramic and glass production process is based. Firing ceramics, whether for small artistic pieces or large industrial batches, requires maintaining precise temperatures that can range from 900°C to 1300°C. Within this range, every degree matters, as it affects the structure, strength and aesthetics of the final product.

When the temperature is too low, the ceramic may not achieve the right hardness, resulting in brittleness and vulnerability. On the other hand, too high a temperature can lead to deformation, cracking or over-firing, which will irreparably damage the product. Uneven glazing or undesirable chemical reactions on the ceramic surface are other risks that result from a lack of precise heat control.

However, the challenges do not end there. The ceramic firing process must also be repeatable and stable so that each batch of products meets the same high quality standards. Without a proper regulatory system to ensure constant control over every step of the process, a manufacturer risks not only defective products, but also significant financial and reputational losses. That's why advanced technologies that enable accurate temperature control and monitoring are essential to success in this demanding industry.

How do modern kiln controllers improve the firing quality of ceramics? Our solution

In order to meet the increasing demands on the quality of ceramic firing, Rohde has relied on modern kiln controllers supplied by Jumo. A key component of this solution is the Imago 500 temperature controller, which provides exceptional precision thanks to its multi-zone temperature control capability. This allows even heating of the batch, which is key to avoiding common defects such as cracks, uneven glazing or insufficient ceramic hardness. The Imago 500 also allows the programming of complex temperature profiles, giving full control over each firing step, adapting the process to the specific needs of different materials.

In addition, Rohde has introduced the dual-channel Dicon touch controller, which makes managing thermal processes much easier with its state-of-the-art touch screen. This controller allows operators to monitor and control different furnace processes simultaneously, increasing production flexibility and enabling rapid adaptation to different requirements.

Also integral to this system are the Logoscreen 601 and 700 screen recorders, which record and visualize data on temperature measurements and other key parameters in real time. This allows Rohde to accurately monitor every stage of production, as well as meet audit and quality requirements through detailed process documentation.

All these elements work in full synergy to create an advanced solution that has allowed Rohde to raise quality standards, increase process stability and repeatability, and manage production more efficiently. As a result, Rohde has strengthened its position as a leader in the ceramic and glass furnace industry, offering its customers products of the highest quality.

How have advanced temperature controllers improved the firing quality of ceramics in Rohde kilns? Customer benefits

The implementation of advanced temperature controllers has significantly improved the quality of Rohde's products, providing precise control over the ceramic firing process. As a result, the company was able to eliminate defects such as cracks or uneven glazing, which directly translated into better quality products. The stability of the firing processes, achieved through modern controllers, guaranteed the uniform quality of each batch of products, which is crucial in mass production.

In addition, meeting stringent quality and auditing standards has been made possible by carefully monitoring and documenting thermal processes. The partnership with Jumo allowed Rohde to increase operational efficiency, reduce costs and strengthen its position in the international market, supporting the company's continued growth and satisfying customers worldwide.
