Proposal to increase the number of shelf levels for firing setter ceramic substrates and firing jigs.
Setter ceramic substrates optimized for the firing process, diverse ceramic technologies, and technology development that meets customer applications.
■Background We have developed a ceramic substrate optimized for "firing setters" by leveraging the characteristics of porous ceramics and utilizing our in-house integrated processes, such as printing on fired ceramic substrates, to meet the increasingly diverse needs of customers utilizing firing processes. Recommended for those who want to "fire more at once!" ■Usage Improving production efficiency in "batch vacuum furnaces" used in firing processes is a significant challenge. We often hear requests to "fit as many works as possible into a single firing process." By utilizing the "manufacturing technology for thin ceramic substrates" that we have cultivated, it is possible to increase the number of setter layers. This allows for an increase in the number of works that can be fired in a single process. In cases where there are space constraints in a firing furnace as illustrated, replacing conventional ceramic plates (7mm thick) with "our ceramic substrates for firing setters (1mm thick)" enables an increase in the number of shelf layers from 16 to 18, resulting in a 12% improvement in firing loading efficiency. Additionally, even with the same number of works, "thicker works" can be fired, allowing for a wider range of applications for the firing furnace.

basic information
■It is possible to increase the number of setter layers. When the height constraint is 720mm, the conventional product (left photo) can accommodate 16 layers, while our developed product (right photo) can accommodate 18 layers. *If the distance from the work surface to the upper shelf does not change, height improvement is possible by the thickness of the setter. ■Thicker workpieces can be fired. With the same number of work layers, our developed product can accommodate workpieces that are "more than 5mm thicker" compared to the conventional product (left photo).
