Surface treatment lines

The processing stages of surface treatment lines: galvanic treatment and fluxing

The surface treatment lines perform various different processing stages used in many fields of application, such as automotive engineering, fashion, microelectronics, watchmaking, jewellery manufacturing and so on.

Surface treatment lines are used to prepare any kind of metal for craftsmen or other industrial machinery to work with. Here we will describe two of the most common procedures: galvanic treatment and fluxing. A galvanic treatment is applied to clean, degreased or acid-treated metal surfaces. The aim of the treatment is to give the surface an aesthetically pleasing appearance, as well as making it stronger and more resistant to oxidation and corrosion.

Surface treatment lines immerse the metal in a liquid solution with a continuous flow of current, so that the metal ions can deposit on the newly-treated surface. Following immersion, the surface is carefully polished.

The second procedure is called fluxing: this is a preparation stage that is indispensable in the galvanization of ferrous materials. As the material destined for immersion in zinc has just been cleaned, it is necessary to protect the surface that is to be galvanized with a special protective film, using a fluxing procedure, so as to prevent further oxidation of the material.
