The steel material phosphating process has the purpose to produce a surface conversion layer, at thin and compact thickness strongly anchored on the surface, in order to facilitate the cold deformation or the further drawing operations. It exists with different types of phosphate. For rod wire, the most frequently used is the zinc phosphate. After phosphating, an opportune covering with lubricating layer on the phosphated surface is necessary

Considering the downstream process from rod to fine wire, be it single or multi-wire production, the in-line annealing process is as important as the wire drawing process itself, because it must ensure the required mechanical and electrical properties (elongation, mechanical strength and conductivity), maintain the wire diameter and roundness defined by the final die, and for metal-plated wires, ensure the integrity of the wire coated surface

OTOMEC Srl is pleased to now present the new complete line for the electro zinc plating of carbon steel wires with large diameters up to 8.5 mm. The new OTO 4 XL electro zinc line represents an innovation for the wire industry.
