Product Manufacturing Process

The manufacturing process of nanocrystalline transformers includes several carefully controlled steps to ensure high-quality production. Initially, the raw materials, typically iron-based alloys with elements like silicon and boron, are processed to form a melt-spun ribbon. This ribbon is rapidly cooled to achieve an amorphous structure. The amorphous ribbon is then subjected to annealing under specific conditions, including the presence of a magnetic field, to induce nanocrystalline formation. The resulting nanocrystalline material is characterized by its tiny grain size, usually less than 100 nanometers. This material is then cut, shaped, and wound into the desired core form. The finished cores undergo rigorous testing to ensure they meet the required specifications for magnetic properties, dimensions, and performance before being integrated into transformers. This meticulous process ensures that the nanocrystalline transformers produced in the factory offer superior efficiency, thermal stability, and DC current immunity.
