Aluminum die casting is a more common tool, used in many places, is a very important part, but if it encounters problems in the process of use how to solve it? Let's take a look at the use of aluminum die casting and surface treatment methods.
First,powder spraying (i.e. powder spraying) : powder spraying is the use of powder spraying equipment to spray powder coating to the surface of the workpiece, under the action of static electricity, the powder will be uniformly adsorbed on the surface of the workpiece, forming a powdery coating.
Second, baking paint treatment: the real baking paint process is to spray aluminum alloy after phosphating, spraying and then baking, such a coating is not only anticorrosive and bright and wear-resistant, not easy to fall off.
Three, oil injection treatment: oil injection is the name of the surface coating processing of industrial products, oil injection processing is generally specialized in plastic oil injection, screen printing, pad printing processing; EVA, rubber shoe material color change, screen printing. With spraying line, screen printing line, pad printing machine and other equipment, and according to customer requirements, the production of high temperature resistance, friction resistance, UV resistance, alcohol resistance, gasoline and other products.
Fourth, oxidation treatment: aluminum alloy surface oxidation, suitable for conductive oxidation, aluminum or aluminum profiles, suitable for anodizing.
5. Sandblasting treatment: Spray a layer of fine sand on the surface of aluminum alloy products to enhance the friction coefficient of the contact surface, which can enhance the reliability of the connection. Sand thickness, grain is also very different.
