What is the function of household appliance hardware etching?

Simply put, the etching process is an extension of the metal stamping process, which is also called photochemical etching, and some people call it corrosion. Hardware stamping is die-opening stamping, but the stamping process is rough, with large tolerance and low precision, which cannot be solved for parts with high roughness. Etching process solves the demand for high-precision parts in industrial production. Etching is to transfer the drawing to the steel plate by photochemistry, and through the principle of chemical reaction, the unnecessary part is corroded away, and the part of the product remains. There are many manufacturers of metal etching, such as Shenzhen Huasheng and Zhuolida. Zhuolida's website introduces the etching process in detail, so you can know about it.
