Moisture is the biggest enemy of metal. It sits on metallic surface and erodes surface bit by bit. Moisture peels metallic surface and in the long run makes it weak. A good example of moisture eating metal is rusting of iron. But a metal can be prevented from coming into contact with metal finishing coating.
The finishing would not only protect the metal from rusting but also improve its look. For instance, you can give the metal a definite color matching with its functionality. If it is a small machine, you can coat it in the color that suits to its uses. Or you can coat a piece in different colors to improve its visual appearance. The process of metal finishing coating covers both look and safety of metal.
The process involves coating metal with a powder that makes a thin protective film on metallic surface. First of all the metal is cleaned and dried to remove moisture and dust from its surface. When it is ready, it is sprayed with a special type of powder made of molecules. The second step is heating the powder so that its molecules become one. The process of metal finishing coating completes with the metal getting heated and cooled.
When it is cooled, the metal piece can be used for the purpose for which it is made. If it is a spare part, it can be used in the machine for which it is made. If it itself is a machine, the metal finishing coating makes it ready-to-use.
