Machining Custom High Precision 99.8% Al2O3 Alumina Ceramic Frame for Industrial

Specification of the ceramic parts:

1. Material options: 95~99.8% alumina(Al2O3), Zirconia (ZrO2), Silicon carbide (SiC), Silicon nitride (Si3N4)
2. Forming method: Dry pressed, Ceramic injection molding, ISO pressed and Hot pressed, Extrusion and so on
3. Type of ceramic parts: ceramic tube, ceramic ring, ceramic rod, ceramic housing, ceramic cap, ceramic frame
4. Specification: Available outer from 1mm to 500mm, available length from 10mm to 1000mm
5. Tolerance: dimensions less than 100mm with 0.005mm, greater than 100mm with 0.01mm
6. Surface treatment: polishing to be diamond-like surface, glazing, metallizing for ceramic to metal bonding

Prime features of alumina ceramic parts :

1. Wear & abrasion resistance: Alumina is extreme hard technical ceramic with superb wear resistance

2. High-temperature ability: withstand up to 1650°C in oxidizing and reducing atmospheres

3. Chemical inertness, resistant most of the strong acid and alkali, and does not rust forever

4. Electrical insulation: The insulation breakdown is up to 18KV at least

5. Great mechanical properties, hardness, compressive and flexural strength are much higher stainless steel

6. Chemical corrosion resistance under high temperature, even if with strong acid or alkali

7. Protective atmospheres or high vacuum at high-temperature to eliminate contamination or impurity.

8. Low material cost in high-level applications than other technical ceramics


Description of high precision alumina ceramic parts:

As the sintering process will cause around 13% to 20% shrinkage for alumina ceramic parts, that means there is around 13% to 20% change in dimensions between green alumina ceramic body and sintered ones. In order to achieve precision fitting in the specific application, sometimes, fired alumina ceramic parts need to be machined to reach high accuracy size and tight tolerance by diamond tools. Our facility offers a selection of precision process, including fine grinding, lapping, CNC machining, laser cutting and so on.
We offer a selection of purities ranging from 95 – 99.8%. Our factory has access to many different types of shaping methods, including dry pressing, hot pressing, ceramic injection molding, ISO pressing, tape casting, and extruded.
Alumina ceramic is characterized by high hardness, wear resistance, low erosion levels, high-temperature resistance, corrosion resistance, and chemical stability. Furthermore, it can be highly polished making it a mirror surface to reduce friction at the fitting, working status. So alumina ceramic parts are extensively used in medical, electronic, electrical, machinery, chemistry, new energy, military, aerospace and so on.

The application of alumina ceramic parts:

Due to high purity alumina versatile characteristics, high precision alumina ceramic parts are widely used as ceramic mechanical seals, ceramic semiconductor parts, ceramic machine components, electrical ceramic insulators, ceramic waveguides, ceramic measuring components, fiber optical application.

Manufacturing flow chart of technical ceramic parts

We have in-housing comprehensive manufacturing types of equipment, including forming, sintering, CNC machining,

precision grinding, laser cutting and so on, it helps us to control the quality very well, also it greatly benefits cost control.


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.
