Advantages of ceramic insulation bars:
 
1. Refractory.
2. Self Lubricating.

3. Long Service Life.
4. Good Polished Surface.

5. Environmental and Healthy.
6. Superior Mechanical Strength.
7. High Corrosion and Wear Resistance.
8. Good Insulation Performance Precision.
9. High Temperature and Pressure Resistance.
10. High Purity Zirconia and Alumina Ceramic Material.

• High hardness, long service life, not easy to break and wear resistance.
• Non-conductive, anti-static, ceramic material itself with the insulation of electricity and magnetism properties.
• Corrosion resistance, high temperature resistance, can be applied to a specific environment, such as acid and alkali resistance.

Production process:

One-stop production, from the raw material (powder) to final products, control the quality strickly of every production link.
