Methods to prevent rust and corrosion of metal stamping parts

Hardware stampings have been widely used in our daily life. Due to the wide range of applications, the quality requirements for hardware stampings are also constantly improving. For example, the surface corrosion and erosion of hardware stampings is a very common problem. For the treatment of this problem, many users do not want to see at present, so the rust and corrosion problems of hardware stampings appear, See how the hardware stamping parts processing manufacturers deal with and prevent? Next, Ningbo SV plastic hardware factory will give you a detailed introduction, as follows:

1. The metal stamping parts will use the electroplating process in the processing process. The processing methods include galvanization, copper electroplating, copper nickel alloy, etc. When meeting customers with low commodity requirements, generally speaking, the product needs can be considered for galvanization.
2. For the surface treatment method of metal stamping parts, the cost of galvanizing is low. Its advantages are corrosion resistance and not easy to rust. Its disadvantages are that it is not possible to persist in the glossiness of the commodity surface for a long time.
3. In a relatively cold and wet or dark natural environment (such as outdoor precipitation) or in the middle of a cold and wet environment (such as near the water pipe), the galvanized surface of metal materials will become soft with erosion, and the skin will turn white and blister like molting at the initial and early stages. The surface of the metal stamping parts will not be exposed until the galvanized layer is intact and etched, and the maintenance of the galvanized layer will be lost. After losing the coating, the hardware configuration will rust, and with the passage of time, it will become more and more serious, thus losing the ability to apply it.
4. When the metal stamping parts are interrupted to be galvanized, the surface of the thickened galvanized layer is required. On the basis of thickened zinc coating, paint a layer of transparent paint. After carrying out these two aspects, the application service life of the metal stamping parts can be greatly increased. Minimize the placement of metal stampings in a dark, damp and cold environment.
