AI-Powered supplier vetting
SummaryThe supplier is a professional magnetic-materials and magnetic-device supplier engaged in production, sales, R&D, and import/export. It holds an ISO 9001:2015 certificate, operates five production lines, has a 3,018.0 m² manufacturing plant, and reports 21–30 quality-control staff. Product inspection is described as 100% inspection with documented instructions. The supplier provides sample-, design-, full-, minor-, and flexible-customization, 3D design, ODM, and OEM services, and reports new products during the past year. After-sales support includes debugging, maintenance, repair, training, and equipment installation, but no overseas warehouses, showrooms, agents, branches, or offline trade-show participation are reported. Financial figures are not assessed or disclosed here. Customer-specific cases are not identified in the provided information.
Supplier typeThe supplier explicitly identifies as a professional technical supplier and conducts production and sales of magnetic steel sheets, magnetic materials, and magnetic devices, together with related R&D and sales activities. Its reported ODM and OEM capabilities further support its role as a manufacturer and technical supplier rather than only a trading intermediary.
CertificationsThe supplier reports holding an ISO 9001:2015 certificate for supplier management systems. This is explicit evidence of a quality-management certification, although no additional certificates are listed.
After-Sales capabilityThe supplier offers overseas service activities including debugging, maintenance, repair, training, and equipment installation, with service proximity identified to Shanghai Port and Ningbo Port. However, it reports no overseas warehouse, showroom, agent, or branch, and no overseas-service countries are specified, so the evidence supports service availability but not broad overseas infrastructure.
R&D capabilityThe supplier reports professional technical R&D capability, 3D software design services, one year of R&D engineer experience, new products during the past year, and ODM services. It does not provide an SDK, and the limited R&D staffing detail prevents a broader assessment of innovation depth.
Production capacityThe supplier operates five production lines, has a 3,018.0 m² manufacturing plant, and lists sintering, wire cutting, automatic assembly, and magnetization equipment. Its finished-product process includes 100% inspection with documented instructions that are uniformly followed, supporting established production and quality-control capability.
Customization capabilityThe supplier explicitly provides customization from samples, designs, full customization, minor customization, and flexible customization, supported by 3D software design, ODM services, and corresponding design-service capability records. These statements indicate broad product-design and customization coverage.
Client casesThe supplier states that it provides OEM services for popular brands, which is evidence of serving at least some recognized-brand customers. However, no customer names, project details, volumes, or verifiable case studies are provided, so the breadth and quality of its customer track record cannot be fully assessed.
