AI-Powered supplier vetting

SummaryNingbo Dragon Electronics and Technology Co., Ltd. is an integrated manufacturer of linear actuators, motor-related products, and control systems, with stated in-house R&D, production, sales, and one-stop service. It provides OEM services for well-known brands and offers extensive customization options. Production information states annual linear-actuator capacity of 100,000 pieces, with lead times within 15 working days in both peak and off-peak periods. However, the supplier reports no available SDK, no new products launched in the past year, only one R&D engineer, fewer than five quality-control staff, and zero quality-control testing equipment. Overseas service infrastructure is limited: no overseas showroom, agents, branches, or offline trade-show participation are reported. Financial-year and cash-flow years are listed, but no substantive financial performance evidence is provided. Certification, customer cases, and several quality, traceability, and sustainability controls remain undocumented or...

Supplier typeThe supplier describes itself as an integrated company covering R&D, production, sales, and one-stop service. Its stated product portfolio includes linear actuators, multifunctional rotating bed control systems, hybrid stepper motors, drive controllers, micro motors, and related household-appliance applications, indicating a manufacturer rather than only a trading intermediary.

After-Sales capabilityThe supplier reports no overseas showroom, overseas agents or branches, offline trade-show participation, or countries with overseas services. It has procedures for corrective and preventive actions and customer complaints, but no written records, while service-capability assessment procedures likewise have no records; therefore, formal after-sales support is only partially evidenced and overseas coverage is limited.

R&D capabilityInnovation evidence is weak: the supplier reports no available SDK and no new products launched during the past year. It has one R&D engineer responsible for R&D, product improvement, and production support, but this limited staffing does not establish strong innovation capacity.

Production capacityThe supplier states annual linear-actuator productivity of 100,000 pieces and lead times within 15 working days in both peak and off-season periods. However, it reports zero quality-control test equipment, fewer than five quality-control staff, and unknown traceability status, so production capacity is demonstrated but production-control maturity is a material weakness.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. This provides direct evidence of broad product-design and modification support.
