Silicon nitride Si3N4 ceramic plate
Specifications
Type: tube, bush, washer. pin, plate, block, rod, ball, bearing ball
Specifications: standard size & customized size
Advantage:
professional manufacturer with advanced technology of silicon nitride ceramics.
1. Longer service life of forming rolls. Service life of silicon nitride forming rolls is about 9 times and 2~3 times longer than that of metal and tungsten carbide forming roll, respectively.
2. Higher working temperature. Silicon nitride forming rolls could be used at , temperature up to 1000°C. While generally, steel forming rolls can only be used below 300°C
3. Better surface roughness quality of the metal works is achieved
4. Pick-up of the metal works is eliminated
5. Scrap of metal works is reduced
6. Consistency and reliability of metal works is in creased
7. Post-processing of metal works is reduced
8. Productivity is increased
