Custom OEM Solutions

We specialize in custom-sized alumina ceramic wafers, plates, and complex-shaped components tailored to your exact requirements. Our advanced manufacturing capabilities include:

Laser Cutting & Precision Machining (tight tolerances down to ±0.005mm)

Metallization & Thin-Film Coating (for enhanced electrical performance)

High-Temperature Brazing (for robust assembly integration)

Main Features:

1. High hardness

2. High heat resistance

3. Good wear resistance

4. High electrical resistivity

5. High corrosion resistance

Performance:

1. The strong acid and alkali resistance of zirconia ceramic shall be better than other materials.

2. Zirconia ceramics are not easy to wear, with strong durability. The hardness is close to the natural diamond and light than metals, also has the gem properties such as never wear and non - discoloring.

3. Can maintain the mechanical strength under high temperature, can be used in the condition with high temperature.

4. Good surface finish quality, could get more glossy smooth surface. Small coefficient of wear, with quite good self - lubricating function, non - magnetic, electric insulation, static - free, anti interference and radiation.

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
