AI-Powered supplier vetting

SummaryThe supplier operates across waterproofing materials, rubber-related products, mechanical equipment, textiles, chemicals, building materials, and selected medical supplies. It states that it provides OEM services for well-known brands and reports multiple technical patents and ISO9001 certification. Quality assurance and raw-material traceability are identified, but the available evidence also shows no SDK, no inventory, no overseas warehouse or showroom, no valid manufacturing-capacity contract with related subcontractors, and no documented corrective-action or complaint-handling procedures. Lead time is stated as within 15 working days in both peak and off-season, but supplier-service governance documentation is incomplete. Financial records are referenced for 2022–2024, without sufficient detail to assess credibility. R&D resources are limited in the evidence, with one engineer and no available design-control documentation.

CertificationsThe company states that it has passed ISO9001 quality management system certification and holds multiple technical patents. This is explicit evidence of certification and technical recognition, although no certificate number, validity period, or certification scope is provided.

After-Sales capabilityThe supplier states that it has no overseas warehouse or showroom, and it has no written procedures or records for corrective and preventive actions or effective customer-complaint handling. These documented gaps indicate weakly evidenced after-sales service infrastructure.

Production capacityThe supplier reports no valid manufacturing-capacity contract with its related subcontractors and no in-stock capacity. It states an average lead time within 15 working days in both peak and off-season, but service-capability governance lacks written assessment procedures and an approved-supplier list. Overall production capacity is not sufficiently substantiated and includes explicit control gaps.

Customization capabilityThe supplier explicitly states that it provides OEM services for well-known brands and offers products intended to meet varied customer demands. Quality assurance and raw-material traceability are also reported, but the absence of an SDK and formal R&D audit documentation limits evidence for technically complex customization.

Product Q&A

Q:What is NBR rubber?

NBR is a synthetic rubber copolymer made from acrylonitrile and butadiene. It is widely used in oil-resistant and fuel-resistant rubber products.

Q:Which NBR series has the best low-temperature flexibility?

Series 18 has a relatively low acrylonitrile content of 17-20% and generally provides better low-temperature flexibility.

Q:Which NBR series is suitable for fuel hoses?

Series 40, with 36-40% acrylonitrile content, is recommended for applications requiring higher fuel and oil resistance.

Q:Which grade is suitable for oil seals and gaskets?

Series 26 and Series 33 are commonly suitable for oil seals, gaskets and other industrial sealing products. Final grade selection depends on viscosity and performance requirements.

Q:Can NBR be used for rubber rollers?

Yes. Series 26, Series 33 and Series 40 include grades suitable for industrial rubber-covered rollers.
