  China fasteners refer to the parts that are used to connect objects. In combination with different weights of objects, our choices of model and specifications are also different, so that we can meet the weight-bearing problem. Then the surface of China fasteners that have been used for a long time will accumulate a lot of dust, so how should the surface stains be handled?

  1. Electroplating:

  Electroplating refers to immersing the part of China fasteners that need to be electroplated into a specific aqueous solution. The aqueous solution will contain some deposited metal compounds so that after the current passes through the aqueous solution, the metal substances in the solution will precipitate and adhere to the immersed part of China fasteners. The electroplating of China fasteners generally includes zinc, copper, nickel, chromium, copper-nickel alloy, etc.

  2. Hot dip galvanizing:

  Hot-dip galvanizing is to immerse China fasteners of carbon steel into a molten zinc plating tank with a heat of about 510℃, so that the iron-zinc alloy on the surface of China fasteners will be converted into passivated zinc, thereby obtaining a surface treatment effect

  3. Mechanical plating:

  Mechanical plating refers to the use of specific physical and chemical means to impact the surface of China fasteners with the power of the coated metal so that the coated metal forms a coating on the surface of China fasteners through cold welding to achieve the surface treatment effect. The mechanical plating of China fasteners is mainly applied to spare parts such as screws, nuts, and gaskets.
