It is possible to produce high-precision fine-pore ceramics with a minimum aperture of φ0.02mm and a length of 100mm.
Pilot Corporation's ceramics can provide high dimensional accuracy for fine holes and deep holes of less than 1mm, which are difficult to manufacture through machining. Thanks to the expertise in mixing, extrusion molding, and firing developed in the production of mechanical pencil leads, dense and homogeneous molding is possible. The dimensional variation within the same lot is minimized, allowing for the production of single holes, multiple holes, and irregular shapes. By utilizing high-precision fine holes, precise flow control can be achieved. Due to the excellent corrosion resistance of the ceramics, they can be used with corrosive liquids and gases. The materials used are high-purity alumina, zirconia, and aluminum nitride. 【Features】 - Capable of producing fine ceramics with a minimum outer diameter of φ0.3mm and a minimum hole diameter of φ0.02mm - For inner diameters of less than φ1mm, long products with an aspect ratio of over 200 can be produced (maximum length 120mm) - Deep holes can be manufactured with freely adjustable wall thicknesses, from thin to thick - High precision with a dimensional tolerance of ±5% *For more details, please refer to the materials.
