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.

Product Q&A

Q:What products can you provide?

We offer CRGO mother coils, slit coils, transformer lamination, and OEM transformer cores.

Q:Who are we?

Established in 1988, we are a pioneering force in CRGO silicon steel products in China, and the exclusive user of Bao-steel. Our joint laboratory with Bao-steel underscores our commitment to quality and innovation.

Q:How can we guarantee quality?

We strictly adhere to ISO9001:2015 standards. Our engineers conduct meticulous calculations before order placement, and we rigorously test each product post-production to ensure peak quality before dispatch.

Q:Why should you buy from us and not from other suppliers?

With over three decades of expertise in producing transformer cores, we leverage advanced German slitting and cutting systems, including the Georg 800 cross-cutting E-stack machine. Our impressive annual production capacity exceeds 100,000 tons. Selecting a good transformer core is critical because it directly affects efficiency, losses, noise, temperature rise, and lifetime of the transformer.

Q:What is the minimum order quantity?

The minimum order quantity is 1 Ton.
