Faucet polishing process and installation process

1. Faucet electroplating process: the first is ultrasonic wax removal, and the cathode is free of oil. Electricity free oil, activation, roughening, retraction, neutralization, surface adjustment, prepreg, sensitization, speeding, positive electrolysis, negative electrolysis, water washing, neutralization, acid copper, activation, cleaning, nickel plating, recovery, Cleaning, chrome plating, etc. Copper plating can make the plating layer more finely arranged, and the small defects of the faucet's appearance are small pinholes and small air holes can cover up to achieve satisfactory results. The nickel-plated effect improves the corrosion resistance of the faucet and can be highly polished. Chromium plating avoids corrosion and adheres to bright light, and improves appearance hardness and wear resistance. The quality of the electroplating surface treatment is judged by the 24-hour acetate spray test and the coating thickness gauge can be used to determine the thickness of each metal coating. Generally speaking, the thickness of the coating is qualified, and the salt spray test can pass.

2. Faucet installation process: The first thing is to equip all the installation items and parts, and start the connection, which includes detachable connections such as spools, net nozzles, etc., and joints such as joints and water inlet fees. Install the valve core (porcelain core) and use a torque wrench to tighten the gland pin or use a socket torque wrench to lock the porcelain core. In the next step, the water test is checked. The faucet is clamped on the experimental table according to the application status, and the water inlet valves on the left and right sides are turned away, the valve core is opened, the inner cavity of the faucet is pre-flushed, and then the valve core is closed to install the net nozzle rubber pad and Use a wrench and other tools to lightly tighten the net nozzle without water seepage. Do not tighten with excessive force to avoid damage to the parts.

3. Factory inspection of the faucet: After the faucet products are put into the warehouse, the product inspector will conduct a sample inspection. The inspection items include: casting appearance, thread appearance, appearance quality, installation, logo, valve core sealing experiment, faucet sealing function experiment For other projects, strictly implement the sampling plan and judgment criteria. The final check of the quality of faucet products.

Summary: Such a production process with 16 rigorous processes, each process has strict requirements on the manufacturing process. The factory of the brand is in accordance with the principle of leaving the first-class products, the second-class products are not allowed to leave the factory, and the small manufacturers don't care about the repair of the first-class and second-class products, so the price is very different. Therefore, the purchase of faucets should still be selected branded faucets to ensure that any one is a boutique, and small manufacturers depend on luck and character.
