Single-wire or multi-wire electroplating lines for steel wire

Sirio Wire solutions also include cutting-edge units for steel wire electroplating. In the electroplating process, a relatively thin layer of metal is applied to a conductive item, in this case, steel wire, using electrical current. The main goal is to apply additional properties to the surface of the steel wire, namely corrosion protection or lubricity.

The wire functions as a cathode in a conductive solution, while the metal to be deposited, typically activated titanium, can act as the anode. When a direct current is applied to the cathode by a rectifier, the metal ions in the solution lose their charge and are deposited on the wire, creating the plating. The anode slowly dissolves and fills the ions in the bath as the electric current from the circuit flows through it. In the case of insoluble anodes, these are pulled out of the solution; therefore, the metal must be periodically re-loaded into the bath in a special dissolution tank.

The line consists of a series of bath tanks made of welded polypropylene plates and a series of working basins. The work basins are fed by collection tubes, while vertical tubes are used to pump the bath from the storage tank below. Due to the aligned working basin, the wire can be guided in a straight line without deviating or having difficulty with the threading.

It’s critical to have a completely clean wire. Soap and oxide residues from the previous drawing and heat treatment processes must be completely removed to achieve flawless adhesion of the metal to the steel.
