Product Manufacturing Process

The manufacturing process of the China porcelain donut insulator involves several meticulous steps. It begins with the precise mixing of raw materials to create a consistent batch. The porcelain dough is then carefully shaped into blanks, which undergo drying to remove excess moisture. Following this, the blanks are glazed for enhanced weather resistance. The glazed pieces are fired in a kiln to achieve their optimal mechanical and insulating properties. Post-firing, the insulators are assembled with galvanized steel fittings. Rigorous routine and specialized tests ensure each insulator meets stringent quality standards before packaging. This comprehensive process ensures the reliability and long-lasting performance of China porcelain donut insulators, vital for high voltage applications.
