In the field of precision manufacturing, the choice of materials often directly determines the upper performance limit of the product. As functional materials with high hardness, wear resistance, high temperature resistance, corrosion resistance and other properties, precision ceramics are increasingly used in industry. But truly "easy to use" depends not only on the material itself, but also on reasonable customization and matching.

This article combines several typical precision ceramic customization cases we have undertaken recently (customer information has been withheld), from Application scenarios, customization requirements, key parameters and actual effects Starting from the article, we objectively analyze the adaptation logic in different scenarios to help everyone understand more intuitively how to "use precision ceramics in the right place". ".

1. Case 1: Wear-resistant guide parts in automation equipment

Application scenarios

The high-frequency reciprocating motion module in an automation equipment requires long-term stable dimensional accuracy and wear resistance of the guide parts.

Customized needs

• High frequency operation (>1 million cycles)
• Low wear and dust generation
• Dimensional tolerance is controlled at ±0.002mm
• Use with metal shaft to avoid snapping

Material and parameter selection

• Material: Alumina ceramic (Al₂O₃ ≥ 99%)
• Hardness: HV ≥ 1500
• Surface roughness: Ra 0.2μm
• Density: ≥ 3.85 g/cm³

Adaptation logic analysis

Combined with the early material selection principles:

High hardness → reduced wear rate

Low coefficient of friction → reduced risk of sticking

High density → improve structural stability

Alumina achieves a good balance between cost and performance and is suitable for such "high frequency and medium load" scenarios.

Use feedback

The service life is approximately 3 times longer than that of original metal parts

Equipment maintenance frequency dropped significantly

No abnormal wear or chipping

2. Case 2: Insulating structural parts in semiconductor equipment

Application scenarios

Inside the cavity of semiconductor equipment, structural components with high purity and strong insulation performance are required.

Customized needs

• High dielectric strength
• Low impurity precipitation
• Stable vacuum environment
• High dimensional accuracy (matching complex structures)

Material and parameter selection

• Material: High purity alumina ceramic (Al₂O₃ ≥ 99.5%)
• Volume resistivity: ≥ 10¹⁴Ω·cm
• Dielectric strength: ≥ 15 kV/mm
• Surface cleanliness level: semiconductor grade cleaning

Adaptation logic analysis

Based on testing and selection experience:

Higher purity → fewer impurities → reduced risk of contamination

Electrical performance indicators → determine equipment stability

Surface treatment → affects particle precipitation

In such scenarios, "performance stability" takes priority over cost control.

Use feedback

Meet long-term stable operation requirements of equipment

No abnormal particle contamination detected

Good compatibility with the system

3. Case 3: Corrosion-resistant seals in chemical equipment

Application scenarios

In chemical fluid transportation systems, the medium is highly corrosive, posing challenges to seal materials.

Customized needs

• Strong resistance to acid and alkali corrosion
• Does not lose effectiveness after long-term immersion
• High sealing surface precision
• Stable thermal shock resistance

Material and parameter selection

• Material: Zirconia ceramic (ZrO₂)
• Bending strength: ≥ 900 MPa
• Fracture toughness: ≥ 6 MPa·m¹/²
• Thermal expansion coefficient: close to metal (easy to fit)

Use feedback

Improved sealing stability

The service life is extended by about 2 times

No obvious corrosion or cracking

4. Case Summary: Key Selection Keys in Different Scenarios

As can be seen from the above cases, precision ceramics are not "the more expensive, the better", but need to be matched based on specific working conditions.

1. Look at the core contradictions of working conditions

Wear Dominant → Prioritize Hardness

Impact Dominance → Prioritize Resilience

Electrical properties dominate → Prioritize purity and insulation

2. Depend on usage environment

High temperature/vacuum/corrosion → material stability is priority

Precision assembly → Dimensions and processing capabilities are key

3. See Testing and Verification

Dimensional inspection (CMM/projector)

Material testing (density/composition)

Use mock or real testing

5. Our practical principles in customization

In actual projects, we pay more attention to “adaptability” rather than pure performance superposition.

Do not blindly recommend high-cost materials

Provide selection suggestions based on actual working conditions

Support the plan through data and test results

Continuously track usage feedback and optimize solutions

Conclusion

The value of precision ceramics does not lie in the parameters themselves, but in Whether it is truly suitable for application scenarios .

It can be seen from the cases that every link from selection and design to processing and testing affects the final effect. Only customized solutions based on real working conditions and data can exert stable value in practical applications.
