Auto Oxidation Blackening Line Phosphating Machine for Nail and Metal Parts

Auto Oxidation Blackening Line Phosphating machine For Nail and metal parts


Description:

The Oxidation blackening machine is a specialized equipment used for the process of oxidation blackening. It is designed to create a black oxide coating on the surface of metal parts, providing them with enhanced corrosion resistance and an attractive black finish.

The machine operates by immersing the metal parts in a chemical solution, typically a mixture of sodium hydroxide and sodium nitrite. The solution reacts with the metal surface, forming a layer of black oxide. This oxide layer not only protects the metal from rust and corrosion but also improves its aesthetic appearance.

And it's widely used in metal coating, such as, nail, screw and valve......
