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.

I don’t know which material of ceramic I need, what should I 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.

What's your trade terms?

We prefer EXW, FOB and CIF as for terms.
T/T, West Union,30% deposit, 70% balance paid before delivery are greatly appreciated.

What is the processing accuracy of ceramics?

Precision Requirement Example Unit
