Every morning, you will instinctively turn the faucet handle. But turning an original brass casting into a finished wall-mounted faucet is far more complicated than you can imagine. Here is the actual process that takes place inside an ordinary faucet factory.
Most brass faucets are initially made through sand casting or investment casting processes. Workers pour molten brass (heated above 900 degrees) into molds shaped like the main body of the faucet. After it cools and hardens, the molds are removed, and a rough brass shell is obtained. At this point, it looks nothing like a faucet and is dark in color, heavy in texture, and covered with scratches and flash lines.
The rough castings enter the CNC machine, where excess brass material is removed, internal water channels are drilled, threads are cut, and a smooth installation surface is machined. A faucet body may require multiple processing procedures. The tolerances are very strict - even a tiny gap could cause leakage later.
After processing, the surface still retains scratches and rough edges. Polishing workers use a series of different coarse and fine polishing wheels - from rough grinding to fine grinding - to make the surface shine. This process is mainly done by hand, and the difference between skilled polishing workers and sloppy operators is immediately visible in the finished product. Cheap faucets often cut corners here.
The polished faucet body undergoes electroplating treatment - usually first coating with a layer of nickel to prevent corrosion, and then coating the surface with a chromium layer to achieve a mirror finish. The faucet is immersed in the electroplating tank and the metal is attached to the surface through an electric current. If the process is done well, this coating can last for many years.
Each faucet will undergo a water pressure test before shipment - if there is leakage, it will be returned for reprocessing.
