CERAMPRO 3C zirconia ceramic center rods are precision-machined from Y-TZP zirconia ceramic for fixture positioning, alignment, and repeated contact in 3C electronics manufacturing. They are often used in mobile phone assembly fixtures, camera module positioning tools, connector inspection jigs, and automated alignment stations where metal rods may wear, lose accuracy, or leave marks on delicate parts.
Material: Yttria-Stabilized Zirconia Ceramic (Y-TZP / ZrO₂)
For 3C fixture parts, zirconia ceramic is valued for its toughness, wear resistance, and smooth polished surface. A well-ground zirconia center rod can keep a stable outside diameter during repeated positioning work and helps reduce the risk of scratches or contact marks on electronic housings, glass parts, camera modules, connectors, and other precision components.

| Parameter | Technical Indicator | Application Meaning |
|---|---|---|
| Material | Y-TZP Zirconia Ceramic | Suitable for precision fixture contact and positioning parts |
| Density | 6.0–6.05 g/cm³ | Dense ceramic structure for stable mechanical performance |
| Hardness | 1200–1350 HV | Helps resist wear from repeated fixture contact |
| Flexural Strength | 900–1200 MPa | Suitable for small precision rods used in alignment tools |
| Fracture Toughness | 8–12 MPa·m1/2 | Better impact tolerance than many conventional ceramic materials |
| Outside Diameter Tolerance | ±0.005 mm to ±0.01 mm | Important for fixture repeatability and center positioning |
| Roundness | 0.002–0.005 mm | Helps maintain consistent contact during positioning or insertion |
| Straightness | Controlled according to length and diameter | Especially important for long or slender center rods |
| Surface Roughness | Ra ≤ 0.2 μm; Ra ≤ 0.1 μm available for suitable designs | Polished surface helps reduce friction and visible contact marks |
| Custom Features | Chamfer, step, groove, hole, slot, flat end, polished contact area | Produced according to fixture drawings or samples |
Note: The above values are typical reference data. Final tolerance, surface finish, straightness, and inspection requirements should be confirmed according to rod size, fixture structure, contact area, and actual assembly conditions.
| Material | Main Characteristics | Best-Fit Applications |
|---|---|---|
| Zirconia Ceramic | Smooth surface, good toughness, wear resistance, stable outside diameter | 3C fixture center rods, alignment pins, inspection jigs, positioning supports |
| Alumina Ceramic | High hardness, good insulation, economical ceramic option | General ceramic pins, insulating rods, and low-impact positioning parts |
| Silicon Nitride Ceramic | Good strength, thermal shock resistance, and mechanical reliability | Higher-load guide parts, automation tooling, and demanding mechanical contact parts |
| Stainless Steel | Easy to machine, but may wear, deform, or leave contact marks after long-term use | General fixture rods where surface marking and wear are not critical |

It is a precision zirconia ceramic rod used for center positioning, alignment, guiding, and support in 3C electronics fixtures and automated assembly equipment.
It is commonly used in mobile phone assembly fixtures, camera module positioning tools, connector inspection jigs, loading fixtures, and automated alignment stations.
Zirconia ceramic has a hard, smooth, and wear-resistant surface. Compared with worn metal rods, it can help maintain positioning stability and reduce the risk of scratches or visible contact marks on delicate electronic parts.
Yes. It is designed for repeated fixture contact where outside diameter stability, wear resistance, and surface quality are important for consistent positioning.
Yes. Diameter, length, chamfers, steps, grooves, holes, slots, flat ends, and polished contact areas can be customized according to fixture drawings or samples.
For suitable sizes and structures, outside diameter tolerance can typically be controlled within ±0.005 mm to ±0.01 mm. Final tolerance depends on size, length, structure, and inspection requirements.
Yes. The contact area can be precision ground and polished to reduce friction, contact marks, and surface damage during fixture operation.
Yes, but long or slender rods need technical review. Straightness, grinding stability, handling risk, and packaging protection should be evaluated before production.
Common inspection items include outside diameter, length, roundness, straightness, surface roughness, chamfer size, end-face quality, and special fixture-related dimensions.
Please provide drawings or samples, dimensions, tolerances, contact area requirements, surface finish, quantity, fixture application, and inspection standards. This helps us evaluate the machining process and quotation more accurately.
