AI-Powered supplier vetting

SummaryThe supplier is a limited company offering casting products and graphite products, with stated annual graphite production of 16,000 tons. It identifies as a professional technical supplier, provides 3D software design and multiple customization options, and reports one R&D engineer plus SDK availability. Export activity is established, with 51%–70% of sales from exports and 11 years of exporting experience, but no overseas showrooms, agents, branches, or offline trade-show participation. Quality-related procedures exist for corrective/preventive actions and customer complaints, although written records are absent; quality assurance status and raw-material traceability are unknown. The supplier reports 21–30 quality-control staff, a one-month off-peak lead time, broad export markets, and port access through Qingdao, Dalian, and Tianjin. Evidence for certifications, customer cases, and financial strength is insufficient.

Supplier typeThe supplier is explicitly described as a professional technical supplier and a limited company. Its stated product scope includes casting products, while graphite products are identified in its production information; it is not part of a larger company group.

After-Sales capabilityThe supplier has procedures for corrective and preventive actions and customer complaints, but no written records are available. It also reports no overseas showroom, agent, branch, or overseas service country, indicating limited documented after-sales infrastructure.

R&D capabilityThe supplier reports one R&D engineer, SDK availability, professional technical-supplier status, and 3D software design capability. However, it launched no new products in the past year, so the evidence supports technical capability but not strong recent product innovation.

Production capacityThe supplier reports graphite production of 16,000 tons annually, 21–30 quality-control staff, broad export-market coverage, and a one-month off-peak lead time. These stated production and operational figures provide explicit evidence of production capability.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization, together with 3D software design services. This directly supports a broad customization capability.

Product Q&A

Q:How does your factory control quality?

All bearing parts undergo 100% strict inspection before and during production, including crack detection, roundness, hardness, roughness, and geometry size, meeting ISO international standards.

Q:How do you guarantee product quality?

Each production step and finished products are inspected by the QC department before warehousing. NG goods are strictly prohibited from entering the completed goods warehouse.

Q:How long is your delivery time?

If goods are in stock, delivery takes 5 to 10 days. If out of stock, it takes 15 to 20 days, depending on the quantity.

Q:Do you accept OEM and custom orders?

Yes, we accept OEM and can customize products according to your samples or drawings.

Q:What are the main applications for these rings?

They are used as sealing elements in pumps and valves, bearings, bushings, hot zones in furnaces, and electrochemical cells.
