Zirconia ceramic PIN needle

PIN materials mainly include cemented carbide and ceramics. Ceramics have unique advantages as PIN needle materials. At present, the manufacture of ceramic PIN needles mainly uses powder injection molding and other processes, and the precision and high-precision back-end processing makes the tolerance reach ±0.001—±0.0005mm. The specifications of ceramic PIN needles are generally customized according to the drawings provided by customers. At present, zirconia ceramic PIN needles are mainly used in optical communication and other fields.
