Common surface techniques for showerheads

Conclusion: Prioritize electroplating and carefully choose the baking paint process
Electroplating: The most common process, often manifested as silver. A good electroplating layer has almost no bubbles on the surface, which will quickly fade away when exposed to water vapor. It can be tested by blowing air onto the surface of the showerhead. In addition, the national standard stipulates that the electroplating layer of the showerhead needs to undergo a 24-hour salt spray test, and the corrosion resistance performance needs to reach level 9 to be considered qualified. Many big brands can reach the highest level of level 10, so be sure to check and inquire when purchasing. Electroplating is a process that uses electrolysis to attach a layer of metal film to a metal surface. A protective layer is formed on the surface of the substrate to enhance the corrosion resistance and wear resistance of the shower, and to improve its appearance glossiness and aesthetics. The high-quality shower electroplating process on the market mainly adopts three-layer electroplating, which includes bottom layer copper plating, to seal the substrate and increase adhesion; Intermediate nickel plating (multi-layer nickel plating process is also used in high-end products), achieving the effect of anti-oxidation and anti-corrosion; Surface chrome plating, due to its stability in air, can maintain surface glossiness for a long time. A small number of businesses promote the use of "five layer electroplating", "six layer electroplating" and other methods for showerheads, attempting to guide the electroplating process to be better with more coatings. However, in reality, the opposite may be true. "Five layer, seven layer electroplating" is often used to compensate for defects in the substrate and manufacturing process. Due to poor substrate quality or poor craftsmanship, the issue can be resolved by adding a coating.
