Using Nd₂Fe₁₄B permanent magnet material, it has the characteristics of high remanence, high coercive force, and high magnetic energy product. The magnetic energy product can reach an ultra-high value and can absorb objects far exceeding its own weight, providing stable and strong magnetic force for electronic devices. For example, in the data line anti-interference scenario, it can effectively shield high-frequency noise and ensure the purity of signal transmission.

(II) Significant structural advantages
The elliptical cross-section design is better in installation adaptability and strength than the traditional circular structure. When applied to data cables, the thickness in the long axis direction is large, which improves the strength of the magnetic ring and the stability of installation, and is not easy to fall off; as a magnetic suction part, it fits the special-shaped structure of some electronic components to enhance the magnetic suction fit and firmness.
(III) High processing precision
Relying on advanced powder metallurgy and CNC processing technology, the dimensional tolerance is controlled within ±0.02mm, and the aperture and shape are precisely adapted to the installation of electronic wires and components, ensuring the reliability of working with other parts, and meeting the high-precision requirements of precision electronic equipment for accessories.
III. Product details
From the R&D end, we focus deeply on the miniaturization and high-performance needs of the electronics industry, and use magnetic simulation technology to optimize the magnetic circuit design to ensure that the elliptical parts release the maximum magnetic efficiency in a limited space while avoiding magnetic field interference. The production process strictly follows the precision manufacturing standards. The raw materials are melted, powdered, and pressed into shape by medium frequency induction, and then vacuum sintered and tempered to enhance the magnetic properties. Subsequent grinding, drilling and other processing procedures rely on high-precision equipment to ensure dimensional accuracy.

In the surface treatment stage, different coatings can be selected according to the application scenario, such as epoxy resin coating commonly used in the electronic communication field, which has both insulation and strong protection; galvanized coating is selected for automotive electronic scenes to improve resistance to moisture, heat and salt spray. Before leaving the factory, the magnetic performance tester and image measuring instrument are fully inspected to ensure that the magnetic flux, size and other parameters meet the standards. For example, the magnetic ring used for data lines will simulate the high-frequency environment to test the anti-interference effect.

Whether it is used for magnetic charging and signal shielding of consumer electronics, or precise magnetic positioning of industrial equipment, this elliptical magnetic hardware precision electronic part has strong magnetic properties, precise structure and reliable quality to lay a solid magnetic foundation for the efficient operation of electronic systems, help products achieve stable magnetic attraction and anti-interference functions in compact spaces, and promote the development of electronic equipment towards a smarter and more sophisticated direction.
