Manufacturing Process And Forming Technology of Iron Laminations

The manufacturing process of iron laminations requires a combination of material characteristics and application scenarios, utilizing multiple procedures to achieve precise control over structure and performance.

 amorphous alloys. Once materials enter the production phase, they are first processed into preset dimensions via cutting. The cutting method must balance precision and efficiency to avoid concentrating internal stress, which could adversely affect magnetic properties.

• Lamination Stacking: This process involves stacking multiple thin sheets in a staggered arrangement, utilizing insulating co

• atings to isolate interlayer currents and reduce eddy current losses. It is suitable for scenarios with high requirements for loss control.

• Integral Casting: This method uses molds to shape molten material in a single step, making it ideal for products with complex structures and strong integration needs.

During the forming process, temperature and pressure parameters must be strictly controlled to ensure uniform internal material structure and prevent defects such as porosity and cracks.

• Annealing: This process eliminates machining stress, optimizes thematerial's magnetic domain structure, and improves magnetic permeability efficiency.

• Surface Insulation Treatment: This enhances inter-sheet insulation performance by spraying or dipping insulating materials, further suppressing eddy current losses.
