Reputation depends on quality, quality comes from Hard!
Alumina Ceramics:
Since the ceramic ferrule blank contains a small hole of 0.1 mm and the requirements for dimensional concentricity are high, only the technique of ceramic injection molding (Ceramic Injection Molding) is possible. The ceramic ferrule manufacturing process is divided into two parts, namely blank manufacturing and precision machining. Firstly, the specially treated yttrium-stabilized nano zirconia powder raw material is used for granulation, injection molding in a special mold, and then sintering at a high temperature. The second part is to process the blank through a series of precision grinding to achieve sub-micron processing precision, so as to obtain a ceramic ferrule with good rigidity and high precision.
properties: High hardness, high strength, wear resistance, corrosion resistance, high temperacture (1600°), good thermal diffusivity, good insulativity, low cost etc.
