What packaging do you use to ensure ceramics are safe?

We pack the ceramic products tidily with foam protection inside the carton, plastic box, and wooden box.

Do you accept custom orders?

Of course, besides substrates with standard dimensions, we also produce custom substrates according to your requirements for dimensions, structure, surface roughness, and metallization.

Would you provide our order's inspection report and material test certificate?

Yes, we can provide these documents upon request.

AI-Powered supplier vetting

SummaryThe supplier is identified as a trading company with export activity and reported annual productivity of 220 tons of boron nitride ceramics. It offers extensive customization, ODM, and OEM services, supported by two R&D engineers and documented design-development records. Quality and service procedures are documented, but finished products are checked by packing staff and the supplier reports zero quality-control test equipment. ISO9001:2015 and CE certifications are stated. Financial records are referenced for 2022–2024, but no substantive financial performance details are provided. The supplier has no overseas warehouses, showrooms, agents or branches, and has not participated in offline trade shows. No specific customer names or verifiable customer cases are supplied.

CertificationsThe supplier reports an ISO9001:2015 management-system certificate and CE product compliance certification. These stated certifications support quality-management and product-compliance capability, although certificate scope and validity details are not provided.

After-Sales capabilityTwo technology engineers are responsible for technical support for after-sales service, and the supplier reports documented and followed procedures for customer complaints and corrective/preventive actions. This is explicit evidence of an established after-sales process.

R&D capabilityThe supplier reports new products during the past year, provides ODM services, and has two R&D engineers responsible for new product development. It also has design input, output, review, verification and validation documents available for audit, although no SDK is available.

Production capacityReported productivity is 220 tons of boron nitride ceramics, with a stated lead time of within 15 working days in the off-season and one month during peak season. However, zero quality-control test equipment and finished-product checking by packing staff indicate a documented weakness in production quality-control resources.

Customization capabilityThe supplier explicitly offers customization from samples, designs, full customization, minor customization and flexible customization, alongside ODM capability. These repeated service declarations demonstrate broad customization coverage.
