Aluminum oxide ceramic shaped part with a central protrusion and hole

The aluminum oxide ceramic irregular shaped part with a central protrusion and hole is a high-precision, high-performance special ceramic structural part designed and manufactured according to specific working conditions and functional requirements. It is not a standard product, but a customized “shaped” part produced through advanced ceramic molding and processing technology.

Core features: As the name suggests, the most prominent feature of this product is a protrusion (or boss) in the middle, and the entire or protruding part has precision machined through holes or blind holes. This unique geometric shape is designed to meet specific positioning, fixation, insulation, flow guidance, or transmission functions.
Basic material: High purity alumina (Al ₂ O3) ceramic is used as the core material. Usually, according to performance requirements, the alumina content can be extended from 92%, 95% to 99% or even higher. The high aluminum content ensures excellent overall performance of the product.
Core value: This design cleverly combines the material advantages of alumina ceramics with specific structures, providing efficient and reliable solutions to industrial challenges in extreme environments.

What problems can the product solve for you?
In many harsh industrial environments, traditional material components such as metal and plastic often perform poorly. Our aluminum oxide ceramic shaped parts with raised holes in the middle were born to solve the following pain points:

1. Solve the problem of rapid wear and tear:
   Pain point: In equipment that operates at high speeds and experiences frequent friction, metal parts are prone to producing wear particles that pollute the environment, or self wear that leads to loss of accuracy and shortened lifespan.
   Solution: Alumina ceramics have extremely high hardness (second only to diamond and silicon carbide), and wear resistance is over 266 times that of manganese steel. It can greatly extend the service life of equipment, reduce the frequency of downtime and replacement, and lower maintenance costs.
2. Solve the problem of high temperature insulation:
   Pain point: In high temperature environments, ordinary insulation materials (such as plastics) can melt, carbonize, and lose their insulation properties, leading to equipment short circuits or malfunctions.
   Solution: Aluminum oxide ceramics are excellent insulators, and their insulation performance does not deteriorate with increasing temperature. Even at high temperatures above 1000 ° C, they can maintain stable insulation characteristics, ensuring the safe operation of equipment.
3. Solve corrosion and pollution problems:
   Pain point: In strong acid, strong alkali, or reactive atmospheres, metal components will quickly corrode, not only damaging themselves, but also contaminating raw materials (such as lithium battery materials, semiconductor chemicals, food additives).
   Solution: Alumina ceramics have excellent corrosion resistance and can resist the erosion of most acids, alkalis, and organic solvents, ensuring the purity of the production process and product quality.
4. Resolve weight and inertia issues:
   Pain point: In automated equipment that requires high-speed start stop or motion, the weight of metal components increases inertia, affecting response speed and control accuracy.
   Solution: Ceramic materials have a lower density than steel, making components lighter and helping to improve equipment speed and positioning accuracy.

Typical application areas
With its unique structure and material properties, this product is widely used in the following high-tech and industrial fields:
Semiconductor manufacturing equipment: used as end effectors, positioning pins, and insulation fixing columns on wafer transfer robotic arms. Its high hardness, dust-free and wear-resistant properties, and ultra-high cleanliness perfectly meet the demanding requirements of the semiconductor industry for pollution-free and high-precision.
Lithium battery production equipment: ceramic bearing sleeves and insulating spacers used as guide rollers and tension rollers in processes such as coating, rolling, and cutting. Corrosion resistance can resist electrode slurry corrosion, and wear resistance ensures long-term dimensional stability.
High temperature industrial furnaces and heat treatment equipment: used as supports, connectors, guide rails, and insulators inside the furnace. The middle protrusion is used to locate and support the heated workpiece, and the hole is used to insert thermocouples or fix bolts. High temperature resistance and insulation properties are crucial.
Automation and Precision Machinery: Wear resistant sliders used as high-precision guides, ceramic components for linear modules, and adjustment seats for optical equipment. The lightweight and high rigidity of ceramics help improve the dynamic performance of equipment.
Medical and analytical instruments: used as insulation brackets, sample holders, sensor protective covers, etc. in detection equipment, their biological inertness and chemical resistance ensure the accuracy of detection results.
Chemical and textile machinery: used as corrosion-resistant guide wheels, nozzles, valve components, etc.
