Rust and oxidation problems of metal stamping parts
With the development of society, hardware products have been popularized in every household. The demand for stamping parts in life is increasing, and the quality requirements for products are getting higher and higher. So how to prevent rust and oxidation problems in the actual application of metal stamping parts?
Most of the metal stamping parts will be electroplated. The treatment methods include galvanizing, copper plating, chrome plating, copper-nickel alloy, etc. If you encounter customers with lower product requirements, galvanizing can meet the demand for products. Compared with the surface treatment method of stamping parts, the cost of galvanizing is lower. Its advantages are that it is both anti-corrosive and not easy to rust. The disadvantage is that it cannot maintain the smoothness of the product surface for a long time.
Especially in a relatively humid or dark environment, such as outdoor rain, or in humid places such as next to water pipes, the galvanizing on the surface of the hardware will become thinner and thinner as it is corroded. In the early stage, the surface will turn white, blister, peel, etc. Until the galvanized layer is completely corroded, the surface of the hardware is exposed, and the protection of the galvanized layer is lost. After the corrosion resistance is lost, the hardware will rust, which will become more and more serious over time, thus losing its usability.
1. Try to avoid dark and humid places;
2. When the hardware is galvanized, the surface of the galvanized layer can be thickened, and a layer of transparent paint can be sprayed on the basis of the thickened galvanized layer.
