Annealed EI Silicon Steel Core with Low Core Loss and High Dimensional Accuracy for EI Lamination Core

METS manufactures precision EI-54 silicon steel cores for inductors, power transformers, and electromagnetic devices. Made from non-oriented electrical steel laminations, these cores are designed to support efficient magnetic performance and reliable operation in electrical equipment.

The EI-54 core features an E-shaped lamination and a corresponding I-shaped lamination, providing a practical magnetic circuit structure for transformer and inductor designs. The laminations can be customized according to drawing specifications, including thickness, dimensions, center-leg geometry, and hole design.

An appropriate annealing process can help reduce manufacturing-related residual stress and improve magnetic properties, depending on the electrical steel grade and processing conditions. METS supports customized lamination manufacturing to meet specific magnetic, dimensional, and assembly requirements.

From prototype development to batch production, we provide flexible manufacturing support for electrical component manufacturers and OEM customers.

• EI-54 Lamination Design: Suitable for compatible transformer and inductor structures.
• Non-Oriented Electrical Steel: Supports magnetic applications requiring multidirectional magnetic performance.
• Annealing Options: Processing can be evaluated to help optimize magnetic properties.
• Precision Hole Design: Customized holes and geometric features according to technical drawings.

These are representative application scenarios, not claims of specific completed customer projects.

The performance of a laminated magnetic core depends on electrical steel grade, lamination thickness, stamping quality, annealing conditions, stacking accuracy, and the final magnetic circuit design.

METS provides customized silicon steel lamination manufacturing to help customers meet their electrical and mechanical design requirements. By reviewing core geometry, material specifications, hole locations, and processing needs before production, we aim to support consistent component quality and efficient assembly.
