Our magnetic shielding box is a high-performance device designed to meet various special needs. Whether it is the requirement for customized specifications or the special protection applied to precision instruments, it can perform excellently. This magnetic shielding box not only effectively shields magnetic fields, but also performs excellently in uniform magnetic field shielding, providing a stable working environment for precision instruments and ensuring the accuracy of measurement and experimental results.
Features of shielding function
- High performance magnetic shielding
- Adopting advanced shielding technology, based on principles similar to traditional shielding boxes, such as circuit electromagnetic induction principle. The resistance characteristics of the metal material inside the box enable the formation of eddy currents when the electromotive force generated by the external magnetic field is sensed. The magnetic field generated by the eddy currents is opposite in direction to the external magnetic field, thereby canceling out some of the magnetic field. At the same time, eddy currents generate heat and consume a portion of the radiated magnetic energy inside the metal, achieving a shielding effect.
- According to the principle of electromagnetic field transmission, special metal materials cause impedance mismatch of electromagnetic waves (including magnetic field related electromagnetic waves), resulting in reflection of the magnetic field and continuous attenuation during transmission, greatly enhancing the magnetic shielding effect.
- Customized specifications
- We are well aware that different application scenarios and precision instruments have different requirements for the size, shape, and internal structure of magnetic shielding boxes. Therefore, we provide customized specification services and can create suitable magnetic shielding boxes for both small precision instruments and large equipment according to the specific needs of our customers.
- Uniform magnetic field shielding
- In many precision measurements and experiments, a uniform magnetic field environment is crucial. Our magnetic shielding box can create a uniform magnetic field shielding effect inside the box by carefully designing the internal structure and selecting suitable shielding materials, reducing the interference of magnetic field non-uniformity on the operation of precision instruments.
- Waterproof and dustproof function
- In order to adapt to a wider range of usage environments, especially in situations where there may be water vapor and dust pollution, the magnetic shielding box has waterproof and dustproof functions. The well sealed structural design, combined with special protective materials, can effectively block external moisture and dust from entering the shielding box, protect precision instruments from corrosion, and ensure their long-term stable operation.
Applicable objects and advantages
- Precision instrument protection
- For precision instruments such as high-precision electron microscopes and magnetic resonance imaging equipment, external magnetic field interference may lead to increased measurement errors or even damage to the instruments. Our magnetic shielding box can provide a relatively "pure" magnetic field environment for these precision instruments, ensuring their normal operation and improving their service life and measurement accuracy.
- Multi domain application advantages
- In the field of scientific research, whether it is physics experiments, material research, or magnetic field sensitive experiments in biomedical research, magnetic shielding boxes can provide reliable magnetic field shielding guarantees for experiments, which helps to obtain accurate experimental results.
- In industrial production, the use of magnetic shielding boxes can improve product quality and reduce defect rates for electronic components that are sensitive to magnetic fields.
materials and processes
- High quality shielding material
- Choose metal materials with high magnetic permeability, such as Permalloy, which have excellent magnetic shielding performance and can effectively absorb and reflect magnetic fields, ensuring the efficient shielding ability of the shielding box.
- Exquisite craftsmanship
- During the manufacturing process, precision machining techniques are used to ensure the sealing and structural stability of the shielding box. For example, the interface adopts a special sealing design, which can ensure good electromagnetic shielding effect and achieve waterproof and dustproof functions. At the same time, the manufacturing process of the internal structure has been carefully optimized to achieve uniform magnetic field shielding effect.
