After the chemical degreasing we conduct a second chemical treatment in a jet-cleaning and iron phosphating plant.
The phosphate layer which builds up on the surface of the part guarantees a higher corrosion resistance. Depending on the type of the phosphate and the type of the technology used to apply it, the anti-corrosion resistance of the part could reach more than >750 neutral salt spray.
At this stage of the preparation degreasing is done once more and the phosphate layer builds up on the already cleaned part. The accumulated film assures a good quality of the surface and an excellent cohesion for the next step of the production process – applying of the powder coating.
