What quality checks should be performed before purchase?

Request prototype sample tests (no-load loss, noise), original mill test certificates (MTC), dimensional drawings, and inspect joint consistency and insulation coating.

How are the products packaged for shipping?

Products are packed with anti-rust protection (VCI paper/oil film) in strong wooden crates with shock protection to prevent lamination displacement during transport.

What is the Minimum Order Quantity (MOQ)?

The Minimum Order Quantity is 1 Ton.

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 provide CRGO mother coils, slit coils, transformer laminations, and OEM transformer cores.

Q:How do you guarantee quality?

Our production adheres to ISO9001:2015 standards. Engineers perform calculations before orders, and rigorous tests are conducted post-production before dispatch.

Q:Why choose your company over other suppliers?

We have over 30 years of expertise, use advanced German slitting/cutting systems, and have an annual capacity exceeding 100,000 tons.

Q:What are the key technical requirements for transformer cores?

Key parameters include transformer type, rating, frequency, target no-load loss, core structure (3-leg/5-leg), joint type (step-lap), and lamination thickness.

Q:What materials are recommended for ultra-low loss applications?

For ultra-low loss, Amorphous Alloy is recommended. For standard high efficiency, Grain-Oriented Silicon Steel (GOES) like Hi-B or Laser-scribed Hi-B is used.
