Electrochemical marking or electrolytical marking

ensemble de marquage électrochimique

Electrochemical marking is an unalterable marking on electrically conductive metals. It is also called electrolytical marking because the process requires the use of an electrolyte.

Electrochemical process on a machined part

Our electrolytic marking machines are applicable to several fields of activity: Fragile parts of the aeronautical industry; Nuclear industry; Tooling; Sharpening of knives; Medical instruments; Marking of identification plates; Datamatrix code marking.

These electrochemical marking machines work on ferrous metals, stainless steel, aluminum, inconel and titanium.


Electrochemistry creates a chemical reaction between the metal and an electrolyte. To carry out this process, it is necessary to have an electrochemical marking assembly composed of several elements: Low voltage electrical current generator. Indeed, when the generator produces alternating current, there is oxidation of the metal. On the other hand, when it produces direct current, there is removal of material and etching; It is the electrolyte that will create the chemical reaction on the part, marking head or electrode. The electrode will bring the electric current from the generator to the part to be marked; The stencil will let the electric current and the electrolyte pass on the part to be marked. The electrochemical process is similar to the laser marking, which explains the very close appearance of the marking obtained.

  • Unalterable marking;
  • Economical and aesthetic marking (accessible and efficient marking assembly);
  • No alteration of the tolerances of the part;
  • Very little maintenance on the electrolytic marking machines;
  • Quick and easy marking.
