AI-Powered supplier vetting

SummaryThe supplier operates in metal structures, magnetic materials, transformer-related manufacturing, and distribution switch-control equipment. It demonstrates documented quality, warehouse, supplier-assessment, complaint-handling, and corrective-action procedures, supported by raw-material traceability, 100% finished-product inspection, and nine quality inspectors. It holds ISO9001:2015, ISO45001:2018, ISO14001, and ISO50001 certifications. The supplier provides broad customization, ODM, and OEM services, with five R&D engineers supporting technical confirmation, product design, production, and after-sales service. However, it is not identified as a professional technical supplier, does not provide 3D software design or SDK services, and reported no new products in the past year. Evidence for overseas service coverage and customer cases is limited; the stated overseas-service country count is zero, while OEM for well-known brands is confirmed without customer names.

Supplier typeThe supplier is explicitly not classified as a professional technical supplier. Its stated business scope instead centers on metal structure manufacturing and sales, metal and magnetic materials, transformer-related manufacturing, and distribution switch-control equipment.

CertificationsThe supplier reports ISO9001:2015, ISO45001:2018, ISO14001, and ISO50001 certifications, covering quality, occupational health and safety, environmental management, and energy management.

After-Sales capabilityFive technology engineers are responsible for technical support during production and after-sales service, while complaint handling has a clear procedure with records. However, the stated overseas-service country count is zero, so international service reach is not demonstrated.

Production capacityProduction capability is supported by listed cutting, laminating, testing, and uncoiling/slitting machines, nine quality-control inspectors, two quality-control test-equipment units, and a one-month average lead time in both peak and off-season. The stated business scope also includes multiple relevant manufacturing activities.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. This range is stated consistently across the design-service records.
