U-shaped ceramic clamping piece

U-shaped ceramic clamping parts are U-shaped fixed components made of high-performance engineering ceramic materials, specially designed for clamping and positioning requirements in harsh environments such as high temperatures, high wear, and strong corrosion. Its unique material properties and structural design make it a key component in fields such as semiconductors, photovoltaics, electronic packaging, precision machinery, and high-temperature processing equipment.

Core advantages of the product

1. Excellent wear resistance
   It is made of ceramic materials such as alumina, silicon nitride or zirconia, with a hardness of over HRA85. Its wear resistance far exceeds that of metal parts, and its service life is extended by 5 to 10 times.
2. Extremely high corrosion resistance
   It can resist the erosion of acids, alkalis, salts and organic solvents, and is suitable for chemical treatment, electroplating and corrosive gas environments.
3. Excellent high-temperature stability
   It has a wide operating temperature range (-50℃ to 1600℃, depending on the material), does not deform or oxidize at high temperatures, and is suitable for vacuum high-temperature furnaces, sintering equipment, etc.
4. Good insulation and non-magnetic properties
   Non-conductive and non-magnetic, it is suitable for precision applications such as electronic component clamping, semiconductor wafer processing, and MRI equipment.
5. Dimensional stability and low thermal expansion
   It has a low coefficient of thermal expansion, ensuring that the clamping accuracy remains unchanged under temperature variations and guaranteeing production consistency.

The key problem to be solved

• Fast wear and frequent replacement: Replace metal clamping parts to solve the problems of downtime and high maintenance costs caused by wear.
• High-temperature deformation and oxidation: Maintain shape and performance stability in high-temperature environments to prevent production accidents caused by component failure.
• Corrosion contamination: Prevent corrosive media from damaging the clamping parts, and at the same time avoid metal ion contamination of the products (such as semiconductor wafers).
• Insufficient accuracy: It provides high dimensional stability and a smooth surface, ensuring that the clamping and positioning accuracy reaches the ±0.01mm level.
  Insulation requirements: In the electronics industry, achieve safe and interference-free clamping to prevent short circuits or signal interference.
