4 Today, very economical equipment etchesfrom one ten-thousandth of an inch deep (.0001) for feeler and plug gages to ten thousandths of aninch deep (.010) for aircraft landing gear components and aerospace hardware, which requirepositive traceability throughout the life of the and dental instruments can now be etched and identified without causing stress toextremely thin wall areas. This same principle is now used for hundreds of other identificationpurposes where products were previously labeled, ink or steel stamped .. or not identified at , simple, fast and safe best describe Electro-Chemical singleconstraint to this process is that it must be applied to electrically conductive metal surfaces. It willnot function on painted metal, already-anodized aluminum or through certain heavy phosphatecoatings.

5 However, by deep etching the parts (.002 to .006) prior to any of these non-conductivecoatings, the MARKING shows through very metals, both ferrous (steel alloys) and non-ferrous (aluminum, brass, bronze and copper)and plated metals (chrome, nickel, cadmium and zinc) mark extremely well because they METHODS , INC.

It issimply made by placing the MARKINGAPPLICATORA over the STENCILB incontact with the part C to be marked.

Theresult is a permanent mark which can only beremoved by buffing or grinding the metal downto the depth of the mark. Occasional blottingof the applicator and stencil in the STENCILCLEANER TRAY E replenishes the electrolytesupply and helps to keep the stencil power unit is equipped with an AC/DC switch. The AC (alternating current) alternately etches out and redeposits acombination of the metal oxide and electrolyte salts, producing a black DC (direct current) charges theapplicator negatively (cathodic) which dissolves metal out, etching a frosted or clear mark. To prevent corrosion, the partsmust be thoroughly cleaned after MARKING to remove any residual special skill is required to operate theequipment except pride in doing a good job.

7 Electro-Chemical MARKING does not deform, weaken or fracture the metalbecause molecular structure is not altered beyond the depth of the etch. MARKING such as steel stamping, dot peen orelectric arc etching alter the grain structure of the metal in the area of the mark, causing possible stress or fracture to theparts. Laser MARKING creates a heat zone around the mark METHODS , INC.
