AI-Powered supplier vetting

SummaryWeiqi presents evidence of structured relay manufacturing and service processes, including batch traceability, supplier/material controls, sample inspection reports, reliability analysis, and documented complaint and corrective-action procedures. It holds ISO9001:2015, CCC, and UL certifications and offers ODM and OEM services. However, the supplier has no valid manufacturing-capacity contract with its related subcontractor, no overseas warehouse or showroom, no available SDK, and no new products reported in the past year. Financial records are indicated for 2022–2024, but no financial performance details are provided. No Fortune 500 cooperation is reported.

Supplier typeThe supplier is evidenced as a relay and water-valve manufacturer with assembling and winding production lines, inventory capacity, and ODM/OEM service offerings. It also manages raw-material sourcing and provides product samples with inspection reports, but its manufacturing relationship with an associated subcontractor lacks a valid contract.

CertificationsWeiqi states that it holds ISO9001:2015 and product certifications including CCC and UL. It also reports reliability reports for relays and water valves, providing explicit evidence of certification and compliance capability.

After-Sales capabilityThe supplier states that it provides professional after-sales service, with response targets of one working day for 3D issues, three working days for 4D issues, and six working days for 5D issues. Written procedures and records are reported for service assessment, corrective and preventive actions, and complaint handling, while batch codes support abnormal-product traceability.

R&D capabilityThe supplier reports no available SDK and no new products during the past year, which limits evidence of recent product innovation. It does provide ODM services and reports using an AI model for data-driven management, but these facts do not establish strong product-development performance.

Production capacityWeiqi reports inventory capacity, assembling and winding production lines, supplier and raw-material controls, and sample inspection support. A deficiency is explicitly reported because there is no valid manufacturing-capacity contract with its related subcontractor; overseas warehouse capability is also absent.

Customization capabilityThe supplier explicitly offers ODM services and OEM services for popular brands. Its free-sample process and inspection reports further support pre-order product evaluation, although no specific customization scope or engineering details are provided.

Client casesThe supplier reports no cooperation with Fortune 500 companies. No other named customer cases or documented customer references are provided, so the available evidence does not establish a strong customer-case portfolio.
