Main characteristics of the ceramic bushing insulator

1. They offer different grade dimensional accuracy per sintered only, precision machining 
2. They are more cost-effective ceramic parts with equivalent performance among all other technical ceramics
3.. High hardness, it is can be up to 1700 HV, and Super compressive strength up to 2240 Mpa
3. High heat resistance: Alumina ceramic parts offer excellent thermal stability, which means that it is widely used in areas where resistance to high temperatures is essential.
4. Good wear resistance: it is an ideal  choice  to wear parts in high abrasive industry
5. High electrical resistivity: used in all-electric products, electric heating products, and wear-resistant machinery parts.
6. High corrosion resistance: It is insoluble in water and only slightly soluble in strong acid and alkaline solutions. Good chemical stability of alumina leads to high corrosion resistance.
7. We support a variety of customized alumina ceramic parts base on customer's drawing, sample, or reference parameters

 

Description of ceramic bushing insulator

Our industry alumina ceramic parts include tube, sleeve, rod, plate, disc, wafer, ring,  shaft, valves, pump plunger, beam, roller, screw, washer, hunger, spacer, holder, carrier, insulator, fixture, clamp, chuck, nozzle, guide, frame, lining, and beads besides flanged ceramic bushing insulator for electrical industry.
These precision toleranced ceramic components or assemblies are used in a wide range of semiconductor, electronic, electrical, mechanical, chemical, automotive, textile and the other industrial engineering applications, due to their extreme hardness, more resistances to wear, heat, corrosion, high electric insulation, and low thermal expansion.

Packaging proposal and transportation solutions

1. We will keep the ceramic parts inside the inner package to be fixed without moving, then it will prevent them from collision each other, to avoid any cause any chippings during transportation.

2. In addition, the inside of the outer carton will be filled with sufficient protective kinds of stuff.
