Aluminum products regardless of what kind of processing prior to disposal method, the first step is completed prior to disposal into the copper plating is flashing. A flash copper currently used as an appropriate first flash copper cyanide plating bath process. After completing the flash copper, to fully clean, and activation, activation with 1% to 3% sulfuric acid solution, if followed by an acidic copper plating or nickel-plated CNC machining precision metal model aircraft, upon activation, without washing you can directly into the groove plating. If other alkaline plating bath especially cyanide plating bath, the latter must be activated into the groove after two bearing washed before plating. Second, the intermediate coating was flash copper future product design or process should be based on the requirements of the center plating copper electroplating process CNC lathe, a practice center plating base layer can also be said, just to ensure that lax copper flash to and associated power and skill of an acceptable coating, the coating product to reach the requirements should be based on the final selection of the center to the outer coating layer. For example, acid copper plating, nickel-plated or other dark as a center or bottom plating or coating processes used. If the outer coating is silver, even more to the right and then thicker plating copper flash, for example, light acidic copper plating, silver plating and inevitable flash again (or silver plating) after the appearance of the final coating competence to enter plating. Chapter introductions of generic processes, copper, nickel and other processes can be used as coatings on aluminum center plating. Fourth, the appearance of the outer coating is an aluminum coating on the purpose of the demand for coatings plating, decorative coating can therefore also be so utilitarian coating. About electronic plating, the aluminum plating mostly utilitarian coating, a small amount of exterior parts of both function and decorative effect. Purely decorative coating limited to the frame on the handles, knobs, and other signs. Aluminum products are made of aluminum alloy aluminum products from the processing of the main raw material supplies, industrial supplies collectively. In recent years, with the rapid advance of large-scale investment in infrastructure and industrialization process, aluminum as the construction sector and the machinery industry in important application areas of aluminum materials, its production and consumption of the rapid growth of the industry, China also jumped the world's largest aluminum production base and consumer market.
