The process comprises the following steps: sequentially drying, mixing, preforming, crushing, injection molding, thermal debinding, sintering, grinding and the like. Material preparation is the first step in the manufacturing process of ceramic ferrules. The material used is typically zirconia, a type of ceramic that is known. This procedure provides guidelines for heatcure fiber optic connector polishing processes. Kyocera's extrusion molding process creates ferrules with excellent coaxiality, and our precision machining ensures excellent concentricity with precise. Figure 1. Each ferrule is defined by bore. Ceramics are hard, inorganic materials similar to pottery but much more sophisticated.
