Polymer Wire Coating in Place of Phosphating
Sirio Wire srl is an Italian company specialized in the chemical and electrochemical treatment of wire. This includes HCl fumeless pickling and H2SO4 electrolytic pickling, ultrasonic and electrolytic cleaning, electro-plating lines, copper and bronzing lines, phosphating etc.
In this article, let’s focus on a very interesting technology developed in the last years: the use of polymer coating in replacement of phosphate mainly used for cold heading applications but also in some particular case for drawing. This technology, that is sludge-free and can be applied at temperature of about 40°C, has huge advantages in terms of energy savings and water consumption as well as for maintenance.
