Medical Devices

Industry of Medical Devices has become in the last decade one of the big users of Anode Treatment of metals services, certainly the most quickly developing and the most diversified and multiform user.

Anode treatment, and especially Electropolish, grants to metal medical parts a range of unique performances requested for medical applications:

• Brightness, smoothness, increased corrosion resistance of the metal, with no use of foreign coating materials,
• Surface defects removing, stress relieving, reduced adhesion of environmental media components to the surface, improved clean ability of the surface,
• Accurate, micron controlled, reduction of size,
• Treatment of parts sized from tens microns to any needed dimensions applicable in medical devices, of any geometrical configuration.

In case the opposite performances are required (matte appearance, roughness, high adhesion ability), Etching surface treatment substitutes Electropolishing treatment. For granting coloring effects to Titanium parts, Color Anodizing is using. In case the cost is of dominant priority, Passivation or Bright Passivation may be operated.

Finish Line is well experienced in development and mass commercial running of all above processing for metal parts of variety of medical devices, meeting Customers’ needs as concerned both quality and capacity.

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 >>

Clean Room Packing

Packing in Clean Room class 1000 with laminar cameras class 100 allows us to implement packaging procedure for customers’ products having the highest cleanness requirements more >>
