The aluminum die casting manufacturer tells you the polishing treatment and infiltration method of aluminum castings

After the shock light of cast aluminum parts, the surface quality has been very high, and even can reach the "mirror" light, and has a passivation effect. There is no need for further treatment except for the special requirements of customers.

"Electrolytic polishing" can further improve the surface quality. Oxidation can improve corrosion resistance. There's no need for shock light. Dyeing can improve the corrosion resistance and get the required color. There's no need for shock light. Electrochemical oxidation of oxidized metal or alloy of cast aluminum parts. An oxide film is formed on the surface of metal or alloy parts by electrolysis. Metal oxide film changes the surface state and properties, such as surface coloring, improving corrosion resistance, enhancing wear resistance and hardness, protecting metal surface and so on. For cast aluminum parts, anodizing is often encountered, but it has to be said that the process of casting aluminum alloy is very difficult to do. Profile and pure aluminum are very easy to do, which is related to the composition of its own alloy.
