Introduction of ceramic pipes

This time, Pilot Corporation will be exhibiting at the "10th Advanced Ceramics Exhibition [Osaka]" held at Intex Osaka. We will manufacture precision ceramics rods and pipes with an outer diameter of φ3.0 or less and an inner diameter of φ0.02 based on customer drawings, using the extrusion molding technology developed with our sharp cores. The materials will be high-purity alumina, zirconia, and aluminum nitride. We will display a large number of actual samples in various sizes and shapes. We look forward to welcoming you with a complete setup, and we kindly ask for your visit.

The pilot produced pipes made of aluminum nitride (AlN), which excels in thermal conductivity among ceramics, and showcased them at the "Nagoya Manufacturing World 2022" (April 13-15, 2022, at Port Messe Nagoya). The raw ceramic powder was mixed with a binder and kneaded, then extruded and fired at temperatures between 1200 and 1500 degrees Celsius to manufacture the products. Through precise molding and uniform firing, it is possible to achieve ceramics with high density, strength, and purity. The pipes and rods that can be produced have an outer diameter ranging from 0.5 to 6 mm, an inner diameter from 0.02 to 4 mm, and a length of up to 100 mm. It is also possible to create filter-shaped micro-machining with numerous through holes in the extrusion (length) direction. So far, our ceramic products have been adopted in applications such as shafts for bearings, heat dissipation fins, and guide pins for drive components in machinery.
