With the development of society, metal stamping parts have been popularized in every aspect of people's life. In daily life, with the increasing demand for stamping parts, people have higher and higher requirements for product quality. The surface rust and corrosion of stamping parts is a very common problem, so how do we prevent rust and oxidation and other problems? Next, I will show you how to prevent surface rust and corrosion of precision metal stamping parts.
Most metal stamping parts will be electroplated, processing methods include zinc plating, copper plating, chromium plating, copper nickel alloy, etc. When it comes to customers who do not have high requirements for products, generally speaking, galvanized can meet product requirements. On the surface treatment method of stamping parts, the cost of galvanized is low, and its advantages are corrosion resistance and corrosion prevention. The disadvantage is that it can not maintain the smoothness of the product surface for a long time, especially in relatively wet or dark environment (such as outdoor rain) or wet place (such as next to the water pipe). The galvanized surface of the metal will be thinned by corrosion and will turn white in the early stages and when bubbling. Peeling and other phenomena. Until the galvanized layer is completely corroded and loses the protection of the galvanized layer, the surface of the stamped part will not be exposed. Without the galvanizing layer, the hardware rusts and deteriorates over time, thus losing its ability to be used.
So, how can we prevent the loss of this galvanized layer and extend the application time of metal stamping parts? Yi Wei precision summed up the following two points.
1. Try to avoid dark and damp places.
2. When galvanizing the stamping parts, thicken the surface of the galvanizing layer. On top of the thickened zinc coating, spray a clear coat. After completing these two points, the service life of the stamping parts can be greatly extended.
