Summary for electrochemical marking etching Discussion
Electrochemical marking/etching is discussed as a possible way to put logos and part numbers on diemoulds, with the original question asking about achievable depth, electrolytes, power supplies, and limitations. In the only answer provided, Igor Agafonov says he has made deep marks using an electrochemical machine with a vibrator L-2000 from Lamik S.A. He reports a pulse time of 2 mS and an electrolyte of 8% NaNO3, and says the resulting surface roughness was Ra 0.05–0.09. He also notes that he has a photo of the surface, implying the process can produce very fine finishes while still making deep marks. The thread does not give broader guidance on power-supply design or process limits, so the practical takeaway is limited to Igor’s specific setup and results.
Am interested in finding information on the Electrochemical Marking/Etching process.
Have read that it can make deep marks (up to 10 thousandths of an inch/250 microns)and wish to investigate the possibility of using this process for etching logos/part numbers etc on diemoulds for the plastics industry.
Am interested in details such as what electrolytes are used, what sort of power supplies are required, and any limitations that the process has.
Any information/details greatly appreciated.

A. I have made this deep marks using electrochemical machine with vibrator L-2000 ( Spain,Lamik S.A). Time of pulse 2 mS, with NaNO3-8%. I have photo of surface.Ra 0,05-0,09.
