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.
