ã€China Aluminum Industry Network】 1. Anodized parts, if there are no fixtures allowed on the part or the entire surface, leave the process margin for card loading. The anodized parts can be mounted on a universal rack or a special rack according to the shape and size. Keep a certain distance between each fixture to avoid 6061 aluminum plate. Second, aluminum rivets, washers and other small parts can be installed in rivet baskets for anodizing. Before the basket is installed, the rivets are etched and lighted, cleaned, and then put on the basket. When oxidizing, in order to increase the conductive contact and reduce the amount of rework, some aluminum chips can be added to the basket when rivets are installed, and mixed with rivets and washers. After filling, add a cap and fasten it with an aluminum nut. Third, you can shake it for a while and listen for loose voices. If there is a loud noise, you should tighten it again, but do not overtighten it. Before mounting, the hanger must be subjected to alkaline etching or boring to remove the old oxide film on the surface of the hanger. Fourth, when loading and affixing, it is necessary to install the card very firmly, but it is not possible to pinch the parts, especially the mechanically processed threaded parts. The large skin is hung with a medium-sized pylon, and the bolts are tightly tightened to prevent it from falling off when the solution oscillates up and down. Parts made of the same material should be mounted on a rack. It is not permissible for one rack to contain two kinds of materials. 5. Box-shaped parts, tubular parts and machined parts with blind holes must ensure that the holes and openings of the parts are upwards, so that the gas generated during anodizing can be freely excluded, otherwise air pockets will form and the local surface will not be oxidized. membrane.
