Exquisite Manufacturing Process: A Journey of Refinement from Steel to Magnetic Circuit Core
Material Selection and Pre-treatment
Based on the application scenario, we precisely select DT4 electric pure iron, low-silicon or high-silicon steel sheets. All electromagnet cores undergo rigorous composition analysis and magnetic performance sampling before being put into production.
Precision Stamping and Lamination
Using high-precision moulds, the silicon steel sheets are stamped into the required shapes (such as E-type, I-type, U-type). The stamped sheets are then stacked on a fully automated lamination machine with extremely high pressure and positioning precision, and firmly formed by riveting or welding to ensure tightness and no looseness between the sheets.
Critical Annealing Treatment
This is the "soul" process that determines the soft magnetic properties. We place the laminated iron core in a continuous annealing furnace or vacuum furnace for heat treatment under precisely controlled temperature profiles and a protective atmosphere. This process eliminates stamping stress, refines grains, restores, and maximises the material's magnetic permeability, while reducing coercivity.
Precision Machining and Surface Treatment
High-precision grinding is performed on key mating surfaces (such as air gap surfaces and mounting surfaces) to ensure dimensional and geometric tolerances. Finally, surface treatments such as steam bluing, electroplating, or coating with insulating varnish are applied as needed to enhance rust resistance and insulation performance.
Quality Assurance and Attention to Detail: Pursuing Excellence in Every Dimension
| Microstructure Uniformity | Under a metallographic microscope, the material exhibits large, uniform grains with clean grain boundaries and minimal inclusions, direct evidence of superior soft magnetic properties. |
| Dimensional Accuracy and Consistency | For each batch of DT4C AC Relay iron core laminations, key dimensions such as the diameter of the central post and the flatness of the pole faces are ensured to be within strict tolerances through Statistical Process Control (SPC). |
| Surface Quality and Protection | The surface treatment layer is uniform and dense, free from plating defects, blistering, or scratches, effectively preventing rust and avoiding additional magnetic resistance caused by surface irregularities. |
| Magnetic Performance Batch Stability | We use high-precision magnetic performance measuring instruments to monitor key parameters such as permeability and coercivity of the materials through random sampling, ensuring minimal batch-to-batch fluctuations and supporting stable mass production. |
