Dongguan mobile phone shield, has cooperated many times with global top 500 companies + 15 years of ingenuity and focus on precision stamping

Hello everyone, I am a hardware manufacturer of precision shielding covers that is responsible for the production of shielding covers for mobile phones in Dongguan. Today I will bring you some knowledge about shielding covers. Let’s take a look! The mobile phone shielding cover is made of metal materials, such as nickel silver coil. During processing, the insulating layer 2 is first covered on the inner surface of the metal material by plating, spraying, coating or pasting, and then after connecting stamping or single The process of stamping is made into a single shield, and then the subsequent process is processed. Mobile phone shields are also called magnetic shields. They are generally made of magnetically permeable materials. The best is permalloy, but they are expensive. They are usually made of magnetically conductive silicon steel strips or iron. In toroidal transformers What is the main function of the shielding cover? The toroidal transformer using the shielding cover has small magnetic leakage and low interference. For power amplifier transformers, electromagnetic interference can be largely eliminated. The sound quality is quite pure and noise-free. It is mainly used for magnetic shielding, effectively reducing the interference of magnetic field on circuits and electronic components. Hardware, committed to being the best and most professional precision stamping processing factory in the world
