| A bushing is an essential fiber forming device in the glass fiber industry, and it plays a critical role in the glass fiber drawing process. It is generally made of classical or dispersion-strengthened platinum-rhodium alloys that are resistant to high-temperature melting glass erosion. Among the many components of bushings, the baseplates and tips are the core ones that determine the quality of glass fiber products, and it is necessary to comprehensively consider various factors for rigorous design. The manufacturing methods of bushings include the split assembly method and the integral molding method. Recently, the high rhodium price has led to the “de-rhodium” of the bushings materials, and the steady growth in the demand for basalt fiber has made the requirements for bushings with better performance and functions. This paper reviewed the working circumstances, performance requirements, structure design, raw materials and manufacturing methods of bushings, and the future development trends of bushings were prospected. |
