Wire rods are treated with phosphating immersion; semi-finished products of water tank drawing (φ1.5 - 2.5mm) are treated with phosphating online; semi-finished products of direct forward drawing (φ2.5 - 4.0mm) are treated with electrolytic phosphating.

Sludge volume is only 1/10 or less compared to conventional non-electrolytic processes, greatly reducing environmental burden.
Salt spray life after painting reaches 1940h+, more than 2× that of non-electrolytic processes (960h).
Reaction energy is concentrated on the workpiece surface via voltage; no tank heating needed, low energy consumption.
No oxidizers or neutralizers required, eliminating non-film-forming side reactions; easier bath maintenance.
SEM shows finer crystal structure than conventional processes; Ni/phosphate ratio is tens of times higher, with better adhesion.
Film thickness is controlled by adjusting current density (e.g., 5–12V, 5.2–9.4 A/dm²); wide operating window.
Wire-reciprocating electrolytic phosphating takes only 40–50 seconds, far faster than traditional immersion processes.
We provide comprehensive wire production chemical solutions to global customers—from high-performance phosphating solutions to advanced dry wire drawing lubricants.
