AI-Powered supplier vetting

SummaryNingbo Dragon Electronics and Technology Co., Ltd. is an integrated manufacturer of linear actuators, multifunctional rotating bed control systems, hybrid stepper motors, drive controllers, and micro motors, with stated in-house R&D, production, sales, and one-stop service capabilities. It provides OEM services for well-known brands and offers broad customization options. Reported linear-actuator capacity is 100,000 pieces annually, with lead times within 15 working days in both peak and off-peak seasons. However, the supplier reports no available SDK, no new products launched in the past year, one R&D engineer, fewer than five quality-control staff, and zero quality-control test equipment. Overseas service infrastructure is limited, with no overseas showroom, agents, branches, or offline trade-show participation. Financial records are indicated for 2021–2023, but the slices do not provide enough detail to assess financial strength. Certification, customer cases, and formal quality-system effectiveness...

Supplier typeThe supplier is presented as an integrated manufacturer and service provider for electronic and electromechanical products, including linear actuators, motors, controllers, and related systems. Its stated own R&D, production, sales, and one-stop service structure supports classification as an OEM/ODM-type manufacturer rather than a trading-only supplier.

R&D capabilityThe company states that it has its own R&D function, but only one R&D engineer is reported, no SDK is available, and no new products were launched during the past year. These explicit limitations outweigh the general claim of R&D capability and indicate a weakly evidenced innovation position.

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

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. This is consistent with its stated integrated R&D and production model and provides clear evidence of broad customization capability.
