Friends who have only seen the appearance of the shielding box will probably think that the shielding box is just an "iron box", right? However, the material of the shielding box is mainly sheet metal or aluminum alloy (cast aluminum process), and pure iron cannot guarantee the shielding performance of the shielding box.

The wave-absorbing materials of the shielding box are generally divided into wave-absorbing foam and wave-absorbing glue, and ferrite tiles. These are all materials that can handle radiation well and can absorb the reflected waves of wireless signals inside the shielding box. Generally, in the manufacturing process of shielding boxes, most of them are treated with wave-absorbing foam or wave-absorbing rubber, which can make up for the lack of surface finish of the box. It is worth noting that this absorbing material will be affected by changes in time, temperature, humidity, etc.



Depending on the model of the shielding box, the size of the box is also different, and the naturally selected absorbing materials are also different. Small-scale shielding box equipment generally chooses wave-absorbing cotton, for example, mobile phone shielding box, wifi shielding box, Bluetooth shielding box, etc. It is a more economical and reliable solution to take wave-absorbing cotton, which can meet the requirements of testing or Reduce costs for customers.
