Achieving Mass Production of Small Ceramics with Complex Shapes
Leveraging Kyocera's extensive technical expertise in raw materials, die molding, and injection molding, we have achieved mass production of small ceramics with complex shapes that are difficult to manufacture using molding methods such as pressing, CIP, and extrusion.
Furthermore, by improving molding technology, we have enabled mass production of thin-walled parts which were previously difficult to manufacture.
Features
- Available for Stable Mass Production of High-Precision Ceramics (level of tolerance ± 0.01mm)
- Supports Requirements for Complex and Sophisticated Shapes, such as thin walls (thickness 0.02mm min.) and small diameters (0.08mm min. through holes)
- Customizable Using Kyocera’s Diverse Materials Lineup to Match Customer Required Characteristics.
*Numbers are reference values based on actual products and may vary depending on the required shape.
Design Samples
Case 1
Mass production of suction nozzles with 0.08mm diameter through holes (1,000 pieces/lot)
Case 2
Mass production of ultra-thin parts (0.02mm) and complex shape parts

PICK UPSilicon Nitride SN240O
Silicon nitride (material code:SN240O) has superior thermal shock resistance and high-temperature strength in addition to excellent mechanical properties which typical engineering ceramic materials Alumina and Zirconia have. And SN240O has smaller specific gravity comparing to typical Alumina and Zirconia.
