Electropolish is a powerful anode treatment process turning the metal surface to outstandingly bright & smooth, corrosion resistant, stress-relieved, defectless, burrs free, stain/spotless one. Electropolish is as well a succesfull, and in some applications irreplaceable, instrument for on micron-level size control and correction. (View gallery to see parts appearance after Electropolish.)
The king of anode treatment processes, Electropolish, was invented at the dawn of the 20th century, intensively researched uhtil 50th, ant then started its rapid industrial development culminating nowdays as a power instrument for metal surface beneficiation for modern burst industtries like ultra fine precisious mechanics, optics, electronics, and especially medical devices.
Finish Line has developed and runs for its customers Electro-polishing Processes for Austenitic and Martensitic Stainless Steels, Titanium & Alloys, Nitinol, CoCr Alloys, Bio Dur Alloys, Aluminum & Alloys, Copper & Alloys.
The size of parts treated at our Electro-polishing lines may be from tens microns to 500 mm and more, with capacity up to thousands units per 8-hours shift, dependings on parts dimensions.

Anode Treatment

Anode treatment beneficiates metal surface through metal dissolving and oxidation. In case no coating is allowed, Anode Treatment is a way to enhance your parts’ surface qualities. more >>


Passivation is a classic anode treatment to improve corrosion resistance of metals, comparing to not treated parts, through completing natural formation of metal oxides surface layer. more >>

Bright Passivation

Bright Passivation improves corrosion resistance of metals, comparing to not treated parts, removes spots from previous processing and provides the parts with brighter appearance. more >>


Etching is an old craft which technically comprises a vigorous anode treatment process, widely exploited in industry. Etching metal surface as a whole makes it uniformly rough and porous more >>

Color Anodizing

Color Anodizing is a unique Titanium only applied process granting to metal surface a wide spectrum of controllable vivid interference colors, which are stable, uniform and repeatable more >>

Surface preparation

Surface preparation ensures the after Anode Treatment surface features as aimed. It includes both quality improving (like de-burring) and surface beneficiation (like surface roughening) more >>

Surface cleaning

Surface Cleaning is an essential completing operation after any Anode Treatment intended washing the surface from leftovers of previous treatment, using purified water at the end step more >>
