Technical Parameters

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
