The faucet plating process: first, ultrasonic wave removal, and cathode power release oil. Electric oil removal, activation, coarsening, recovery, migration, neutralization, surface conditioning, prepreg, sensitization, acceleration, cation electrolysis, cation electrolysis, water washing, neutralization, acid copper, activation, cleaning, nickel plating, recycling, Cleaning, chrome plating, etc. Copper plating can make the electroplated layer get finer structure, small defects on the surface of the faucet, small pinholes, and small pores can be covered to achieve satisfactory results. The effect of nickel plating increases the corrosion resistance of the faucet surface and is highly polished. Chrome plating prevents corrosion and keeps light, improves surface hardness and improves wear resistance. The quality of the plating surface treatment is judged by the 24-hour acetate spray test (the test equipment is a salt spray test machine) and the plating thickness gauge can be used to identify the thickness of each metal plating. Generally speaking, the thickness of the coating is up to standard and the salt spray test can pass.
Faucet assembly process: First of all, equipped with various assembly tools and components, start to connect, including detachable connections such as valve core, mesh nozzle, etc., non-detachable connections such as joints and water inlet feet. Install the valve plug (porcelain core) with a torque wrench to tighten the gland pin or use a sleeve torque wrench to lock the ceramic core. Install the water foot or water level and the hex nut with a 10mm hex wrench (pre-installed seal “O” ring on the water inlet and water level). The bathtub faucet is equipped with a water separator switch. The next step is to test the water. First, the faucet is clamped on the test bench according to the state of use. Open the inlet and outlet valves on the left and right sides respectively, open the valve core, pre-wash the inner cavity of the faucet, and then close the valve plug to install the mesh nozzle and the mesh nozzle. And use a wrench and other tools to gently tighten, do not seep water, can not be too hard to lock, so as not to damage the parts. In the next step, the pressure test is carried out to check that there is no leakage on each sealing surface as a qualified product. The test qualified product is transferred to the assembly line with a pressure cap, a handle, a hot and cold water mark, and finally an accessory is attached to wipe the package and packing.
Factory inspection of faucet: After the faucet product is put into the warehouse, the finished product inspector will carry out sampling inspection. The inspection items include: casting surface, thread surface, appearance quality, assembly, marking, valve core sealing test, faucet sealing performance test and other projects. Strictly implement the sampling plan and the principle of judgment.
After understanding such a comprehensive faucet production process, do you think that the high-priced faucet on the market is worthy of this price? The faucet is a common and essential household item, we must choose a good product.
