Ceramic Locating Pin
Ceramic locating pins are used for precise positioning and alignment in high-precision assemblies, particularly in environments requiring wear resistance, electrical insulation, and temperature stability. Compared with metal pins, ceramic pins maintain shape and accuracy even under long-term stress or corrosive conditions. They are widely used in electronics, semiconductor packaging, medical devices, and automated machinery.
- High precision and dimensional stability
- Superior wear resistance
- Electrically insulating and non-magnetic
- Thermal shock and corrosion resistance
- Customizable shapes and tolerances

Advantages of Ceramic Locating Pin
- High Dimensional Precision: Because ceramic pins can be machined to tight tolerances, they offer excellent repeatability in alignment tasks.
- Exceptional Wear Resistance: As a result, they maintain accuracy and surface integrity even under frequent insertion and removal.
- Thermal and Chemical Stability: Therefore, they perform consistently in high-temperature and corrosive environments without degrading.
- Electrical Insulation: In addition, their non-conductive nature makes them ideal for use in electronic or high-voltage applications.
- Non-Magnetic and Inert: Consequently, they are suitable for use in magnetically sensitive assemblies or chemically reactive processes.
- Long Service Life: Thanks to their hardness and stability, ceramic locating pins require less frequent replacement than metal alternatives.
Applications
- Precision Assembly Fixtures: For example, they are used to align components during automated manufacturing or robotic assembly.
- Electronics and Semiconductor Fabrication: Because of their cleanliness and non-conductivity, they are used in circuit board positioning and wafer alignment.
- Medical Device Manufacturing: In addition, they support precise alignment during cleanroom assembly of surgical or diagnostic tools.
- Aerospace and Automotive Components: Ideal for use in jigs and fixtures where thermal resistance and repeatable accuracy are essential.
- Optical and Laser Equipment: These pins maintain alignment in sensitive systems where vibration and thermal drift must be minimized.
- High-Temperature or Chemical Processing Systems: Lastly, they provide robust alignment solutions where metal pins would degrade or react.
