Wear-Resisting Alumina Ceramic Flanges Parts
My factory looking for distributors.
All products through the German DIN standards: DIN43724 / DIN43725 / DIN40680
Advantages of Wear-Resisting Alumina Ceramic Flanges Parts
1. The surface of alumina ceramic flanges parts is extremely smooth with low roughness. This enables a tight fit to be formed when cooperating with other components, effectively reducing or even eliminating medium leakage.
2. Alumina ceramic flanges parts, with their high hardness and wear resistance, can withstand material erosion and mechanical friction, maintaining good sealing performance.
3. Alumina ceramic flanges parts have high melting points and good thermal stability, ensuring that the sealing performance of equipment is not affected by temperature and ensuring the smooth progress of industrial production.
4. In some industrial equipment that requires electrical insulation, the good insulation performance of alumina ceramic flanges parts can prevent current leakage and avoid safety issues caused by electrical faults.
5. Alumina ceramics undergo high-temperature sintering and other processes during the manufacturing process, resulting in a dense and stable internal structure. This enables alumina ceramic flanges parts to have good dimensional stability and maintain precise dimensional accuracy under different working environments and conditions.
Applications of Wear-Resisting Alumina Ceramic Flanges Parts
1. In chemical production, alumina ceramic flanges parts are commonly used as inlet and outlet pipeline connections for high-temperature kilns, ensuring the continuity and stability of the production process.
2. The use of alumina ceramic flanges parts at the busbar connection of high-voltage switchgear can improve insulation performance and enhance the safety of equipment operation.
3. Alumina ceramic flanges parts can meet the requirements of hygiene, corrosion resistance, and wear resistance in pipeline connections on beverage production lines and interface parts of food processing equipment, ensuring the quality and safety of food and beverages.
4. The high mechanical strength and stability of alumina ceramic flanges parts can also ensure that the connection parts remain reliable during frequent use of pharmaceutical production equipment, providing a guarantee for the stable production of drugs.

Factory Equipment
Slip casting moulding: Inject the prepared slurry into the gypsum mold and let it stand for a period of time to allow the gypsum mold to absorb moisture. The slurry forms a uniform body on the inner wall of the mold.
Injection moulding: Inject a slurry containing paraffin into a metal mold at a certain temperature and pressure, and after the body cools and solidifies, perform demolding to prepare ceramic bodies.
Extrusion moulding: Suitable for long tube products, the powder is extruded into shape through an extruder.
