How does the shielding cover work? Let Dongguan shield manufacturer hardware tell you. The shielding cover is mostly made of aluminum and copper dense shell. That is because the metal shell can shield the wireless signal. It is an electrostatic shielding phenomenon. The conductor in the electric field, whether it is solid or hollow, causes the charge on the surface of the conductor due to electrostatic induction. Redistribution, when the electrostatic balance is reached, the field strength at any point inside the conductor (including the conductor cavity) is zero. The wireless signal causes the metal shell to induce current without inducing current inside, so that the inside will not be affected by external electron sources. If you want to know more about the shielding cover, welcome to consult
