Phosphating
We use modern phosphating lines with counter-current rinsing:
- Mn-Ph – Manganese phosphating
- Zn-Ph – Zinc phosphating
What is phosphating?
Phosphating (phosphatisation) is a chemical process that forms a protective phosphate layer on clean steel surfaces. This layer:
- prevents corrosion,
- improves paint and lubricant adhesion,
- reduces friction,
- acts as an electrical insulator.
Our process follows EN 12476 and ISO 9717 standards.
Maximum part size: 1.5 × 1.5 × 1.7 m (W × L × H)
Maximum weight: 5 t
Applications of phosphating
Corrosion protection
Phosphate layers protect machine parts from rust. We impregnate the layer with oil, grease, or wax for stronger resistance.
Cold forming of metals
The phosphate layer, combined with lubricants, reduces friction between tool and material. This makes forming processes (e.g., pipe drawing) smoother and less damaging.
Before painting
Phosphating improves paint adhesion and prevents under-rusting. Thin layers are best – thick layers may cause paint chipping.
Moving parts (break-in process)
Manganese phosphate coatings reduce wear during the run-in period of machine parts. They absorb oil well, shorten break-in time, reduce friction, and lower noise.
