How to prevent rust and corrosion of precision stamping parts

With the development of society, metal stamping parts have been applied to all aspects of everyone's daily life. The requirements for stamping parts are constantly increasing, and the quality requirements for precision stamping parts are getting higher and higher. The surface corrosion of stamping parts is a very common problem, so how to prevent problems such as rust and air oxidation? Next, precision will teach everyone how to prevent rust and corrosion of metal stamping parts. Precision stamping parts will use electroplating process, processing methods include galvanizing, electroplating copper, copper-nickel alloy, etc. When encountering customers with lower requirements for goods, generally speaking, galvanizing can consider product demand. As for the surface treatment of stamping parts, the cost of galvanizing is lower. Its advantage is that it is corrosion resistant and not easy to rust. The disadvantage is that the gloss of the surface of the product cannot be persisted for a long time. Especially in a relatively humid or dark natural environment (such as outdoor precipitation) or in the middle of humid and cold (such as next to a tap water pipe), the galvanized surface of metal materials will become soft with corrosion, and it will be weakened in the early and early stages. The skin becomes white and blisters like molting. Until the galvanized layer is intact and eroded, the surface of the stamping parts is exposed, and the maintenance of the galvanized layer is lost. After the coating is lost, the hardware configuration will rust, and with the passage of time, it will become more and more serious, and then lose the ability to apply it. So, how to prevent this kind of galvanized damage and increase the service time of metal stamping parts? Precisely summarized the following two points: Try to minimize the need to thicken the surface of the galvanized layer when interrupting the galvanizing of stamping parts in a dim and damp environment. On the basis of the thickened galvanized layer, a layer of transparent paint is sprayed. After these two aspects are carried out, the application service life of stamping parts can be greatly increased.
