AI-Powered supplier vetting

SummaryShanghai Wenlida Technology Co., Ltd. is a manufacturer and seller of regulated power supplies, voltage stabilizers, EPS emergency power supplies, harmonic suppressors, automatic doors, and related electrical and control equipment. It reports raw-material traceability, 100% finished-product inspection, ISO9001:2015, ISO14001, and ISO45001:2018 certifications, as well as written procedures for supplier service assessment, corrective actions, and complaint handling. The supplier offers extensive customization and OEM services, has five R&D engineers, and holds one national science and technology progress award, but reports no SDK availability and no new products launched in the previous year. Production-related information indicates a stabilizer production base and supporting testing and production lines, although capacity figures are not provided. Overseas service infrastructure is limited: no overseas warehouse, showroom, agent, branch, or offline trade-show participation is reported. Customer evidence...

Supplier typeThe supplier is identified as a modern enterprise integrating R&D, production, and sales of regulated power supplies, EPS systems, harmonic suppressors, voltage stabilizers, automatic doors, and related electrical and control equipment. Its stated business scope also includes import and export of goods and technologies, supporting classification as a manufacturer with integrated commercial activities.

CertificationsThe supplier reports ISO9001:2015, ISO14001, and ISO45001:2018 management-system certificates. These are explicit certifications covering quality, environmental, and occupational health and safety management.

Production capacityThe supplier describes integrated R&D and production, a large stabilizer production base, ancillary professional testing and supporting production lines, and complete plant processing. It also reports raw-material traceability and 100% finished-product inspection, but provides no quantitative production capacity, making the overall production advantage supported qualitatively rather than fully measurable.

Customization capabilityThe supplier explicitly offers customization from samples, designs, full customization, minor customization, and flexible customization, and also reports OEM capability for recognized brands. These statements directly support broad customization and OEM capability.

Client casesThe supplier reports providing OEM services for recognized brands and a repeat-buyer preference of 50%–80%. It also reports no cooperation with Fortune 500 companies; named customer cases, project details, and independently verifiable references are not provided.
