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 is completed, it is necessary to clean up adequately and carry out activation treatment. The aluminum profile frame is activated with 1% ~ 3% sulfuric acid solution, assuming that the electroplating after this is acid alkaline copper plating 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. Carried out flash went back, copper plating, in accordance with the standards of products or the ability to launch center coating electroplating production and processing, lu: su doors and Windows aluminum coating also can say the trainee on center into bottom plating, flash copper plating in order to better access port only loose to and even the relay for a professional skill of coating, to reach the product to the provisions of the coating.
