Electrolytic Metal Etching setup and marking demonstration

A short demonstration from http://www.trendmarking.com.au on setting up and using the electrochemical metal marking system, used to permanently etch metal products with a contrasting black print similar to laser-marking.

A low-voltage current is applied through a stencil to mark into the surface of a metal product.

Different stencils are available depending on the type of information required, the demonstration shows only "permanent stencils", long-lasting a re-usable electrochemical marking stencils
