Surface treatment

Before painting, metallic surfaces of the parts are duly treated: their quality level is determined, the preparation method and technique are selected, etc., so that the coating would be of high quality.

Abrasive cleaning

If surfaces of the parts are covered with rust, metal oxides, slag and so on, the layers of paint or primer have to be cleaned – this can be done by manually grinding or by abrasive blast cleaning.


Currently the parts are pickled manually, but not automatically. However, if necessary, the pickling in the automatic line could be provided within a couple of months (special area in the coating line is foreseen for this application).


These processes are fully automated in the company.
10 steps of degreasing, phosphatizing with Zn-Mn-Ni phosphate and Chrom-free passivation are used.
