After the preparation of aluminum alloy profile products on electroplating, you can enter the steps of aluminum electroplating. No matter what kind of pre-treatment method is used, the first process after pre-treatment to electroplating is flash copper plating.

    A: flash copper plating

    At that time suitable for flash copper plating bath is mainly hydrogen cyanide copper plating professional skills.

    After the flash copper plating, 4080 aluminum profiles should be fully cleaned, T-type aluminum alloy keel and activation treatment, activation with 1% ~ 3% sulfuric acid solution, assuming that the electroplating after this is acid alkaline copper or nickel plating, after activation without water cleaning can be immediately into the plating tank. If it is other alkaline plating solution, especially hydrogen cyanide plating solution, the activation must be washed after 2 times before plating into the tank.

    Two: central plating

    To carry out the flash copper plating to the back, according to the standard of product plan or ability to carry out the electroplating production and processing of the center coating, the center coating on probation can also be said to be the bottom coating.
