Circular structure opening design, flange style, alumina ceramic components

The annular structure opening design flange style alumina ceramic component is a functional ceramic component with a special geometric structure made of high-purity (usually 92%, 95%, or 99% alumina content) alumina (Al ₂ O3) ceramic material through precision machining.
Its core feature lies in the organic combination of “circular structure”, “perforated design” and “flange style”:
Circular structure: refers to a component whose main body is a sturdy circular ring, providing excellent mechanical strength and stability, and effectively resisting deformation and stress.
Hole design: Various shapes and specifications of holes (such as central circular holes, surrounding screw holes, irregular through holes, etc.) are precisely machined on the annular substrate according to customer needs to achieve specific functions such as fluid passage, line crossing, optical pathways, mechanical fixation, etc.
Flange style: The edge of the component is designed with a flange (flange structure), which allows the component to be easily and firmly installed, docked, and sealed with other equipment or structures, greatly improving the convenience and reliability of integration.
This product integrates the inherent high performance and precise mechanical structure of alumina ceramics, aiming to solve the pain point of insufficient performance of traditional metal or plastic components in harsh environments.

What problems can this product solve for you?

1. Solve the problem of short wear and tear life: The hardness of alumina ceramics is extremely high, second only to diamond and silicon carbide. In applications with particle erosion and component friction, its wear resistance is tens or even hundreds of times that of metals, which can greatly extend the equipment’s operating cycle, reduce downtime and replacement frequency, and lower maintenance costs.
2. Solve the problem of performance failure in high temperature environments: It can maintain stable shape and function in a high temperature environment of 1600 ° C for a long time, without softening and melting like metals, nor will it burn and fail like plastics. Perfect for scenarios such as high-temperature furnaces, sintering furnaces, aerospace engines, etc.
3. Solve the problems of chemical corrosion and pollution: Alumina ceramics have excellent chemical inertness and are resistant to various acids, alkalis, and organic solvents. At the same time, it is oil-free, non-magnetic, not easy to adhere, and will not contaminate the media passing through (such as high-purity chemicals, semiconductor process fluids, food, drugs), ensuring the cleanliness and safety of the production process.
4. Solve the problem of insulation and sealing: It is not only an excellent insulator, but also can achieve high vacuum air sealing with metal parts through brazing and other methods. In power equipment, vacuum chambers, and semiconductor equipment, it can simultaneously serve multiple functions of insulation, support, and sealing, simplifying equipment structure design.
5. Solve the problems of dimensional precision and stability: Through advanced sintering and CNC machining technology, the dimensional accuracy and smoothness of the product can reach extremely high levels. Its low thermal expansion coefficient ensures minimal size changes during temperature fluctuations, ensuring the precision and reliability of the equipment’s long-term operation.

Typical application areas
Semiconductor manufacturing equipment: used as ceramic arms on wafer transfer robots, insulation fixing columns in vacuum chambers, gas distribution plates for plasma etching machines, heating plate supports for CVD equipment, etc., meeting the requirements of ultra-high cleanliness, resistance to plasma bombardment, and high precision.
Industrial pump valves and seals: As mechanical sealing rings, shaft sleeves, valve liners, etc., they are used in pump valve systems for conveying corrosive and abrasive media (such as mortar, acid and alkali liquids), providing a long service life.
Laser and Optical Equipment: As an insulation bracket, mirror holder, beam path window plate flange, etc. for lasers, it provides stable support, precise positioning, and excellent optical performance (after specific polishing treatment).
High temperature heat treatment industry: used for furnace rollers, bearing plates, brackets, etc. in sintering furnaces and muffle furnaces, to withstand extremely high working temperatures without deformation or contamination of products.
Medical and food equipment: As fixed components in bioreactors and wear-resistant liners in food processing equipment, it meets biocompatibility and FDA food grade safety requirements.
New energy and aerospace: used in high-end fields such as insulation separators for fuel cells and sensor protection covers for spacecraft.
