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 ± 0.01 mm)
  • Supports Requirements for Complex and Sophisticated Shapes, such as thin walls (thickness 0.02 mm) and small diameters (0.08 mm 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.
