Can you provide samples for me to test? How much does it cost?

We strive to provide ceramic samples that closely meet your requirements to the best of our abilities.
The samples are completely free, but you need to pay the freight.
For samples with unique shapes that require custom molds, we are open to discussing the mold cost in order to accommodate your specific needs.

We don’t know which material of ceramic we need, what should we do?

No worries! Please provide us with more details about your requirements, such as the intended use, desired properties, and any specific characteristics you're looking for.

With these information, our team can guide you in selecting the most suitable ceramic material for your needs.

We are concerned about the quality of the product we ordered.

We understand your worries and we maintain stringent quality control standards as following:

Test Standard Testing Dimension Pass Rate Standard Range
Appearance Inspection Quantity and Severity of Defects ≥ 97.3% Determined by AQL standard
Dimensional Inspection Size Accuracy and Consistency ≥ 98.1% Determined by ISO 9001 standard
Density Testing Material Density ≥ 97% Determined by ASTM C20 standard
Hardness Testing Surface Hardness ≥ 98.2% Determined by ISO 6508 standard
Flexural Strength Testing Material Flexural Strength ≥ 97.9% Determined by ASTM C1161 standard
Thermal Shock Stability Testing Material Thermal Shock Stability ≥ 98.7% Determined by ASTM C884 standard

*Qualification standards higher than ISO standards

In addition to production line inspections, we also accept inspections from third-party organizations several times a month

While the occurrence of defects is extremely rare, it is an unavoidable possibility. If any quality issues arise, we take full responsibility and will expedite the reproduction process at cost price.

Our commitment is to ensure that our products meet the highest quality standards and promptly address any concerns to ensure customer satisfaction.

What is the processing accuracy of ceramics?

Precision Requirement Example Unit
Surface Flatness Ra ≤ 0.1 μm μm
Dimensional Accuracy Tolerance within tens of μm μm
