PLATECT®Ceramic Setter・Ceramic Saggar

Designing for Firing――PLATECT® is on your side

What's PLATECT®?

PLATECT® is a setter / saggar finding primary applications in firing processes for manufacturing electronic components. The setter is the sole material that is in directly contact with your product in the furnace; thus, the quality of the setter has a major impact on the quality of your product. We succeeded in developing the world’s first plasma spray coated setter. Since launching this technology, it has been adopted by many customers owing to the highly consistent quality results it produces.


Ceramic capacitors are just one of the many kinds of electronic components that use a setter during manufacturing.

We consult with our customers to ensure PLATECT® is custom designed to meet the needs of each of their products to provide optimal application of the technology to the usage conditions. This is one of the reasons our many customers keep choosing our products.

The three elements of PLATECT® technology

PLATECT® comprises three elements: the material and shape of the substrate, as well as the coating material. The performance you seek can be achieved by combining the three elements appropriately.
