Product Introduction
High Performance Ceramic Rings For Industrial Seals and Precision Applications
Why are industrial ceramic rings so special?
1)High-Temperature Resistance: They can withstand extreme temperatures, making them perfect for use in furnaces, kilns, and high-heat machinery.
2)Corrosion Resistance: Industrial ceramic rings resist damage from acids, alkalis, and other harsh chemicals, ensuring longevity in corrosive environments like chemical plants and refineries.
3)Excellent Electrical Insulation: With superior dielectric properties, these rings are ideal for electrical applications, providing safe and efficient insulation in power systems and electronic devices.
4)Mechanical Strength: Their hardness and durability make them suitable for high-stress mechanical components such as seals, bearings, and wear-resistant parts.
Applications of industrial ceramic rings:
1)Chemical Industry: Used in reactors, pipelines, and distillation columns.
2)Electrical Power: Employed in insulators, bushings, and high-voltage equipment.
3)Mechanical Engineering: Applied in seals, bearings, and abrasive components.
4)Laboratory & Research: Utilized in crucibles, boats, and other experimental apparatus.
If you're involved in any of these industries, industrial ceramic rings could be the solution to your operational challenges. Please contact us to discover how these remarkable components can enhance your industrial processes!

Production process
1. Grind and crush the raw materials to be slurry or powder
2. se-different method to making the slurry or powder into semi-finished products
3. Put the semi-finished products into the kiln for dewaxing and sintering;
4. After forming and sintering, Ceramic Sleeves products can also be processed by subsequent CNC precision machining according to the drawing requirements. Then Q/C test.
5. Finally package Ceramic Sleeves by bubble paper or cartons and place it on tray for delivery
