The principle

The electrochemical etching process was developed to streamline the marking of conductive metals. No other process allows such quick, economical and problem-free etching of products made from hard metal, stainless steel, tool steel, zinc, aluminium and brass or with chrome-plated or nickel-plated surfaces, without impairing the structure of the material. The process is an electrochemical one involving a combination of electrical current, time, electrolyte and the material itself.

Application

The electrochemical etching process is used for applying company logos, product designations, dimensional details, manufacturing data, serial numbers, inspection labels, bar codes, functional symbols, assembly and installation instructions and much more. The etching process can be applied manually or semi-automatically in connection with a suitable machine or unit.

Examples of etchable products

Medical and surgical instruments, steel items of all types, fittings, household implements made of stainless steel, containers in the food-processing industry, assemblies for the car industry, pipes, sheet metal, lathe-turned parts etc.

Three quick and easy steps to a successfully etched marking

Place the workpiece to be etched on the contact plate, align the stencil over the workpiece.

Moisten the hand stamp with electrolyte and press it onto the workpiece for about 2-3 seconds. Large markings can be etched by sliding the stamp across the stencil.

After that, the etching process is finished. The inscription is now permanently etched. As a last step, the workpiece is cleaned and passivated with Neutralin.
