After wire drawing, spring steel wire is immersed in a chemical phosphate bath to form a thin crystalline phosphate film on the surface, providing anti-rust protection, friction reduction, and enhanced coating adhesion.
We offer phosphorus-free and boron-free film agents to help steel strand enterprises meet environmental protection emission standards

Hold the three major international system certifications of ISO 9001, ISO 14001 and ISO 45001. We own over 20 patented technologies
Phosphate film as lubricant base extends die life by 30%+.
Short-term anti-rust between processes, no white rust.
Excellent base for plastic/oil coating, no delamination.
Film introduces no hydrogen — spring fatigue life unaffected.
Wide parameter window, consistent film quality batch to batch.
We provide comprehensive wire production chemical solutions to global customers—from high-performance phosphating solutions to advanced dry wire drawing lubricants.
