AI-Powered supplier vetting

SummaryDongguan Qiaofeng Electronics Co., Ltd. is identified as a manufacturer integrating R&D, production, sales, and technical services for cooling fans and blowers, with an independent XIN RUI FENG brand. The supplier reports broad customization, 3D design, ODM, and OEM capabilities, and indicates new-product development during the past year. Production information includes five production lines, 6–10 quality-control staff, and stated annual outputs for AC axial fans, DC axial fans, and blowers. Finished-product inspection instructions are reportedly standardized and followed. However, no supplier-management-system certifications are listed, overseas service infrastructure is absent, and several service-management procedures lack records or formal approvals. The supplier states OEM service for well-known brands, but no specific customer names or documented cases are provided. Financial information is inconsistent or incomplete and cannot support a strong credibility assessment.

Supplier typeThe supplier is explicitly described as a manufacturer integrating R&D, production, sales, and technical services for cooling fans and blowers. Its stated operations include five production lines and dedicated quality-control personnel, supporting classification as a manufacturer rather than only a trading or service company.

After-Sales capabilityThe supplier has written procedures for service capability, corrective and preventive actions, and complaint handling, but reports no written records for these processes. It also has no overseas warehouse, showroom, agent, branch, or offline trade-show participation, while stated lead times are within 15 working days and service quotations can use FOB, CIF, CFR, or EXW.

R&D capabilityThe supplier reports first-class R&D personnel, product development and continuous-improvement capability, new products during the past year, 3D software design services, ODM service, and development of AC, DC, EC, and blower fan series since 2017. However, the total experience of R&D engineers is listed as 1 and no SDK is available, so innovation capability is supported but appears limited in some dimensions.

Production capacityProduction resources include balancing, pressing, tin-dipping, winding, oil-pressing, automatic dispensing, and automatic assembly machines, together with five production lines and 6–10 quality-control staff. The supplier states annual outputs of 3.6 million AC axial fans, 6 million DC axial fans, and 6 million blowers, with standardized finished-product inspection instructions that are uniformly followed.

Customization capabilityThe supplier explicitly offers customization from samples, designs, full customization, minor customization, and flexible customization. It also provides 3D software design, ODM, and OEM services, indicating broad support for customized product development and manufacturing.
