The manufacturing process of ceramic ferrules involves several steps, including material preparation, molding, sintering, and polishing. Its manufacturing requirements are very high, and parameters such as dimensional accuracy, roundness, and surface roughness need to meet standards to ensure the performance and reliability of. With zirconia ceramic powder as a main material, an ethylene-vinyl acetate copolymer, an oleic acid, polymethacrylate, atactic polypropylene and paraffin are added in the mixing process, and thus the prepared zirconia ceramic ferrule is good in abrasive resistance, strong in ageing resistance. Ceramic ferrules and sleeves are often used in optical connectors, attenuators, fiber stubs, and other optoelectronics requiring low signal loss. Kyocera's extrusion molding process creates ferrules with excellent coaxiality, and our precision machining ensures excellent concentricity with precise. At first glance, they may appear easy to mass produce, but these ferrules are made of high-tech ceramics. Ceramics are hard, inorganic materials similar to pottery but much more sophisticated. Hence, H 2 S must be removed from processed petroleum products and pipeline quality natural gas.
