Permanent part marking that changes nothing about the part — and makes its own stencils. The mark takes two to five seconds. Ordering a stencil for a part number you have never marked before takes days. SUPER SET 04 removes that gap: type the content, print the stencil, mark the part, discard it.

This is the configuration to specify when marking content changes from part to part — serial numbers, lot codes, manufacturing dates, unique device identifiers. There is no per-design tooling cost and nothing to schedule.

Who uses it

Serialised production, medical device and instrument identification, aerospace subcontract machining, precision fasteners and fittings, hardened tooling, and contract manufacturers marking different content for different customers from one bench.

Two marking modes

• Black oxide marking — shallow, high-contrast dark mark. What most identification work calls for.
• Deep etch, light marking — recessed mark with real depth, for identification that must stay legible through further finishing, handling or service life.

The compact sets 05, 06 and 07 do black marking only. If a drawing specifies etch depth rather than contrast alone, Set 04 is the one that covers it.

What’s in the box

• EUmark marking unit, 110 V / 220 V, with power and marking cables
• Stencil printer model 410 — 108 mm print width, 300 dpi, USB and Bluetooth
• Stencil design software, included with no licence fee
• Stencil tape 108 mm × 100 m, 1 roll
• Hand stamp (marking head)
• 2 × marking felt, 375 × 500 mm (10″ × 19″)
• Electrolytes M21, M22, M23 and N11 Neutralyte — 200 ml each
• Sample long-life stencil and sample printed stencil

SUPER SET 04A is the same kit with 50 ml electrolyte bottles. Choose 04A to evaluate, 04 to run production.

What the included software does

Stated plainly: the software imports raster images, not vector files. Use the printer for content that changes, and a long-life photo stencil — which EUmark produces from your SVG, DXF, AI or EPS artwork, good for up to 5,000 marks — for content that repeats. Most workshops use both.

How the process behaves

A controlled low-voltage current carries an electrolyte through a stencil into the workpiece, converting the surface chemistry in the exposed pattern. Typical mark depth is 0.025 mm (0.001 in).

• No heat-affected zone and no recast layer — nothing melts
• No residual stress introduced, which matters on fatigue-critical and thin-wall sections
• No burrs and no raised edges, so no deburring after marking
• Corrosion resistance preserved when the mark is neutralised with N11
• Black oxide, clear etch, or white marks on chemically blackened components
• Works on flat, round, concave, convex, hollow and assembled parts

The mark is a conversion of the metal itself, not a coating, so it survives solvents, handling, steam sterilisation and alkaline cleaning.

The four electrolytes

Marking units are broadly similar across the industry. Electrolytes are not, and they are where the result actually comes from.

All EUmark electrolytes are formulated to the requirements applied in medical, aerospace and food-contact production, and a safety data sheet is supplied for every fluid — which quality departments need for incoming inspection and the audit file. A 200 ml bottle delivers up to 20,000 marks.

The table is a recommendation, not a specification. Alloy, condition and surface finish all affect the result, so trial marking on your own material is a required step. EUmark will mark a sample of your material on request.

How to mark a part

1. Switch on the unit and degrease the surface.
2. Print the stencil with the serial number, code or text the job calls for.
3. Fit the felt to the hand stamp and wet it with electrolyte.
4. Position the stencil on the part and press the stamp against it — a few seconds decides contrast and depth.
5. Lift the stencil and neutralise the surface with N11 and a separate cloth.

No extraction, no enclosure, no laser safety programme. The workstation is a bench, and the unit travels to the part when the part cannot travel.
