Ceramic Sleeve  Manufacturers, Traders, Suppliers

We machine your parts with inexpensive manufacturing processes in our own production workshop. These are produced in a fired, hard state from stored semi-finished products. This enables us to achieve a high degree of flexibility and to offer short-term delivery options.
Our manufacturing processes are particularly suitable for prototype construction and individual parts. However, depending on the process, we can also realise small series/series.
We would be pleased to advise you on the choice of ceramic material and help you find solutions for your ceramic-compatible designs.
Don't hesitate, give us a call!

Silicon Carbide characterizes the highest hardness, very good thermal shock resistance and very good chemical resistance. The thermal conductivity of silicon carbide is in the excess much higher than of many metals. Silicon carbide parts find application, where the highest wear and chemical resistance are required.

Ceramic sleeves represent cutting-edge engineering components designed to withstand the most challenging operational conditions. These precision-crafted cylindrical components are manufactured from advanced ceramic materials such as alumina (Al₂O₃), zirconia (ZrO₂), or silicon carbide (SiC), offering exceptional properties that outperform traditional metal sleeves.

Advanced ceramic tubes are made from high-performance ceramic materials, such as alumina, zirconia, and silicon carbide. They are known for their exceptional strength, high-temperature resistance, and diverse applications.

1. Manufacturing Process: The mixture is then shaped into tubes and fired at high temperatures to create strong and durable ceramic tubes.
2. Industrial Applications: Ceramic tubes have many industrial applications. They are used in various fields such as aviation, aerospace, navigation, petroleum, chemical industry, automobile, electronic equipment, metallurgy, electric power, textile, pump, medical equipment, scientific research, national defense and military.
3. Properties: Ceramic tubes are easily machinable and have excellent resistance to high temperatures, abrasives, and chemicals with low thermal conductivity. They are tough and highly polish-able considering their comparatively low densities.

Ceramic sleeves are high-performance components made from advanced materials like alumina or zirconia. Known for their exceptional hardness, wear resistance, and thermal stability, they are ideal for applications in demanding environments.
Ceramic sleeves provide excellent chemical resistance, making them suitable for corrosive and high-temperature conditions. They are commonly used as insulating liners, protective covers, and wear-resistant components in industrial machinery.
