Blue zirconia ceramic locating pins are crafted from Zirconia (ZrO₂) ceramic material through processes including precision forming, high-temperature 

sintering, and precision grinding. They are designed for use in precision equipment, automated tooling fixtures, and positioning/assembly systems. Zirconia ceramics 

offer high mechanical strength and fracture toughness, alongside excellent wear resistance, chemical stability, and electrical insulation properties. Unlike conventional 

metal locating pins, these ceramic alternatives are resistant to rust, thereby mitigating risks such as corrosion, the shedding of oxidized particles, and metal-to-metal 

contamination. They are ideally suited for industrial applications that demand high positioning accuracy, material purity, and corrosion resistance. To meet specific 

customer requirements, these pins can be produced with a blue finish—a feature useful for color-coding, product identification, or ensuring visual uniformity across 

equipment. The specific shade, color uniformity, and durability of the blue finish are determined by the chosen coloring process and material system.

Features

① Precision Positioning · Accurate Dimensions

The diameter, roundness, straightness, and fit tolerances of a locating pin directly influence the accuracy of assembly positioning. Through precision grinding and 

dimensional inspection, key dimensions can be controlled to meet blueprint specifications, making these pins ideal for precision tooling, positioning fixtures, and 

automated assembly mechanisms.

② High Strength · High Fracture Toughness

Zirconia ceramics offer high mechanical strength and fracture toughness, making them suitable for various positioning and support applications, provided that the 

structural design and loading conditions are appropriate. For slender pins, small-diameter pins, or applications subject to lateral impact, careful evaluation of bending 

stress, installation methods, and the risk of edge chipping is essential.

③ Excellent Wear Resistance · Stable Positioning

Zirconia ceramics exhibit superior wear resistance, making them well-suited for operations involving repetitive positioning, frequent insertion/removal, or continuous 

contact. Properly managing fit clearances, surface roughness, and installation loads helps minimize the impact of wear on positioning stability.

④ Corrosion Resistance · Rust-Free · Reduced Risk of Metal Contamination

Unlike conventional metals, zirconia ceramics do not rust or suffer from oxidative flaking, thereby reducing the risk of contamination caused by metal corrosion. For 

applications that require the avoidance of metal-to-metal contact or metal oxidation, ceramic locating pins provide an effective non-metallic solution. Specific corrosion 

resistance should be evaluated based on the contact medium, temperature, and actual operating conditions.

⑤ Electrical Insulation · Suitable for Electronics and Precision Equipment

Zirconia ceramics possess excellent electrical insulating properties, making them ideal for positioning structures that require electrical isolation, the minimization of 

metal-to-metal contact, or the prevention of interference from conductive components.

⑥ Blue Appearance · Facilitates Identification and Differentiation

The blue color allows for visual distinction between different workstations, part specifications, or equipment functions, simplifying product identification and on-site 

management. The color is determined by the material formulation or coloring process; factors such as color consistency, surface condition, and color durability should 

be verified based on the intended operating environment.
