Precision Ceramic Testing & Quality Inspection Capability

At CERAMPRO, quality is built into every stage of manufacturing. From raw material selection to final delivery, we implement a full-process inspection system to ensure dimensional accuracy, material performance, and long-term reliability for demanding industrial applications.
Our quality control process is designed to meet the requirements of semiconductor, electronics, and precision industrial customers worldwide.

1️⃣Incoming Material Inspection

Objective: To verify raw ceramic materials before production and ensure material consistency, reliability, and traceability for precision ceramic components.
●Chemical composition analysis (Al₂O₃, ZrO₂, Si₃N₄, SiC, AlN, BN, etc.)
● Particle size distribution testing (D50 / D90)
●Detection of impurities and metal content
●Raw material batch traceability and supplier quality records
✅Inspection Result:: Qualified raw materials with complete batch traceability records before production

2️⃣Pre-forming Inspection

Objective: To ensure the stability of the powder and the formulation
•Uniformity check of powder mixing
•Testing of moisture content / fluidity
•Confirmation of grouting / dry pressing / isostatic pressing parameters
✅Prevent post-sintering deformation and abnormal pores

3️⃣Green Body Inspection

Objective: To prevent size control failure after sintering
• Inspection of the appearance of the green body (cracks, missing corners)
• Random inspection of the size of the green body
• Weight consistency testing
❌Non-conforming products are directly isolated.

4️⃣Sintering Control

Objective: To ensure that the material performance meets the standards
•Monitoring of sintering curves (temperature / time / atmosphere)
•Batch records and furnace sequence numbers
•Initial inspection of the sintered product appearance (deformation, sintering defects)
✅The entire process parameters can be traced back.

5️⃣Machining Inspection

Objective: To meet high precision tolerance requirements
• Dimension accuracy measurement (±0.001 to 0.01 mm)
• Concentricity / flatness / perpendicularity measurement
• 100% inspection of key dimensions (subject to customer requirements)

6️⃣Visual & Surface Inspection

Objective: To ensure assembly and usage reliability
•Inspection of surface cracks and chipping
•Testing of surface roughness Ra
•Confirmation of coating / polishing quality (if any)
✅Standard: Free of cracks and obvious defects

7️⃣Functional Testing

Customize testing items according to product application
• Hardness test (HV)
• Bending strength test
• Wear resistance / corrosion resistance test
• Electrical insulation / thermal conductivity test (for semiconductors)
• Thermal shock / high temperature test
📌Key point: Focus on application rather than just size

8️⃣Final Inspection & Packing

Objective: To ensure that the customers receivequalified products that are ready for direct use
• Quantity, identification, batch confirmation
• Review of customer drawings and specifications
• Shockproof, moisture-proof, and clean packaging
• Shipping inspection report (COC / Inspection Report)

Quality Commitment

We do not simply manufacture ceramic components — we ensure they achieve reliable performance through strict material control, precision inspection, and quality verification.

Our quality control system supports OEM customers producing ceramic components for semiconductor equipment, optical communication systems, ceramic heating applications, and industrial precision devices, ensuring stable quality, full traceability, and long-term reliability.

Customizable

We have a wide range of technologies such as material technology, process technology, design technology, measurement/evaluation technology, and integrated processes from materials to products in-house, so we can respond to various customizations. Please feel free to contact us first.
