What to do about surface oxidation and rust of precision metal stamping parts

With the development of society, hardware stamping parts have been widely used in various aspects of people's lives. In daily life, with the increasing demand for stamping parts, people's requirements for product quality are also increasing. Rust and corrosion on the surface of stamped parts is a common problem, so how can we prevent problems such as rust and oxidation? Next, I will introduce how to prevent surface rust and corrosion of precision metal stamping parts.

Most metal stamping parts undergo electroplating treatment, including galvanizing, copper plating, chromium plating, copper nickel alloy, etc. When it comes to customers with low product requirements, generally speaking, galvanizing can meet the product requirements. Regarding the surface treatment method of stamping parts, the cost of galvanizing is relatively low, and its advantages are corrosion resistance and rust prevention. The disadvantage is that the smoothness of the product surface cannot be maintained for a long time, especially in relatively humid or dark environments (such as outdoor rain) or damp places (such as near water pipes). The galvanized surface of metal will become thinner due to corrosion and turn white in the early stages and during foaming. Peeling and other phenomena. The surface of the stamped part will not be exposed until the galvanized layer is completely corroded and the protection of the galvanized layer is lost. After losing the galvanized layer, the hardware will rust and deteriorate over time, thus losing its ability to use.
