AI-Powered supplier vetting

SummaryThe supplier is a professional magnetic-materials and magnetic-device supplier engaged in production, sales, research and development, and international trade. It holds an ISO 9001:2015 certificate, operates five production lines, and has a 3,018.0 m² manufacturing plant. Quality controls include stated procedures, 100% finished-product inspection, and 21–30 quality-control staff in one record, although another record lists one quality-assurance and quality-control inspector. The supplier offers broad customization, 3D design, ODM, OEM, and recent new-product development. After-sales support includes debugging, maintenance, repair, training, and equipment installation, but no overseas warehouse, showroom, agent, branch, or offline trade-show participation is reported. Financial credibility cannot be assessed because the provided financial records identify years but contain no financial results. Customer evidence is limited to a statement that it provides OEM services for well-known brands.

Supplier typeThe supplier identifies itself as a professional technical supplier and conducts production and sales of magnetic steel sheets, magnetic materials, and magnetic devices, alongside R&D and sales activities. It also offers ODM and OEM services, indicating a manufacturer with technical-development and contract-manufacturing capabilities.

CertificationsAn ISO 9001:2015 certificate is explicitly reported for the supplier’s management system. This provides direct evidence of certification relevant to quality management.

R&D capabilityThe supplier reports professional technical R&D capability, 3D software design services, recent new-product development, and ODM services. However, it reports no available SDK, and total R&D-engineer experience is listed as one, so the breadth and depth of innovation resources are not fully established.

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. It also reports 100% finished-product inspection with documented and uniformly followed inspection instructions, although quality-inspector staffing is inconsistent across records, with one record stating 21–30 quality-control staff and another stating one inspector.

Customization capabilityThe supplier explicitly offers customization from samples, designs, full customization, minor customization, and flexible customization. It also provides 3D software design, ODM services, and OEM services, demonstrating broad customization and design-to-production support.

Product Q&A

Q:Can magnets be exported?

Sure. Now we can independently approve licenses, and the delivery time has been increased by five times.

Q:Do your magnets support customization?

Yes. We can customize material, size, magnetic strength, plating and special-shaped structure to meet personalized needs.

Q:How to choose different material magnets?

- Neodymium iron boron: Strongest magnetic force, suitable for precision equipment; - Ferrite: Cost-effective, suitable for home appliances and toys; - Samarium cobalt: High temperature resistant, suitable for industrial high-temperature scenarios; - Alnico: Good stability, suitable for instruments.

Q:What is the function of magnet plating? Which has good corrosion resistance?

Plating is used for rust and corrosion prevention. Corrosion resistance order: Electrophoresis > Nickel-copper-nickel plating > Zinc plating > Color zinc plating, which can be selected as needed.

Q:Is there a minimum order quantity (MOQ) for bulk purchases? What is the lead time?

MOQ for standard products is 1000 pieces, MOQ for customized products is 5000 pieces (negotiable); Lead time for standard products is 7-15 days, and for customized products is 15-20 days.
