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.

Supplier typeThe supplier is involved in metal structure manufacturing and related fields, but is not a professional technique supplier.

CertificationsThe supplier holds ISO9001:2015, ISO45001:2018, ISO14001, and ISO50001 certifications, indicating a strong commitment to sustainable development management.

After-Sales capabilityThe supplier has clear procedures and records for handling customer complaints and providing technical support, indicating effective after-sales service capability.

R&D capabilityThe supplier lacks significant R&D output, with no new products developed recently and no SDK availability.

Production capacityEquipped with various machines and a dedicated quality control team, the supplier ensures thorough inspection and traceability in production.

Customization capabilityOffers extensive customization options from samples, designs, and full customization, demonstrating strong customization capabilities.

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.
