Overview

An etched stainless steel nameplate is produced by photochemical machining that cuts graphics, text, serial numbers and apertures into the metal itself rather than printing or engraving them on the surface. Grades 304 and 316L, 0.30–1.50 mm thick, are laminated with dry-film resist, exposed through the artwork and developed, then sprayed with ferric chloride so the unprotected areas recess into a controlled depth. The line width of the finished character is set by the artwork and the side-etch factor, and because the copy is recessed it can be paint-filled and will not rub off with abrasion, solvent or weather.

For a nameplate the governing detail is line width, not overall size, and etched stainless steel nameplate production holds it by balancing etch depth against side etch. A 0.15 mm stroke on 0.5 mm stock is kept crisp by compensating roughly 0.6–0.8 × thickness per side, so fine rules, QR codes and small text do not thicken or close up. The same film repeats identically across a sheet, and the recessed graphics are filled with baked enamel or left raw, giving a durable, flat tag that stays legible outdoors for years.

Parameter Window

• Available Materials: stainless steel 304/316L/430, brushed or mirror finish
• Material Thickness Range: 0.30–1.50 mm (0.5–1.0 mm typical)
• Tolerance: profile ±0.05 mm, etch depth ±10% of thickness, line width ±0.02 mm
• Minimum Feature: 0.15 mm line width, 0.3 mm character stroke at 0.5 mm stock
• Surface Options: brushed, mirror, electropolished, black oxide, PVD, baked enamel fill, adhesive backing
• Compliance: ISO 9001 process control, RoHS/REACH material traceability

Manufacturing Process / Workflow (8 Steps)

1. Artwork Review — Convert files to vector, check stroke width against material thickness, and confirm font, spacing and bleed.
2. Material Selection — Choose 304 for general use or 316L for marine exposure, and confirm finish and flatness.
3. Cleaning & Lamination — Degrease and laminate dry-film resist under heat and pressure so no bubble sits under fine text.
4. UV Exposure — Expose through high-resolution film registered to the sheet edge for panel-level accuracy.
5. Development — Wash out unexposed resist to open the character and contour areas, then inspect for under-developed strokes.
6. Etching — Spray ferric chloride at controlled time and temperature to reach the specified recess without undercutting fine lines.
7. Stripping & Finishing — Strip resist, neutralize, then fill with enamel, brush, electropolish or apply adhesive backing.
8. Inspection & Packaging — Verify character legibility, depth, flatness and colour against the approved sample, then pack on liners.

Core Advantages

1. Copy in the metal: Recessed characters filled with enamel cannot be worn off by abrasion, solvent or weather.
2. Crisp fine lines: Compensated artwork holds a 0.15 mm stroke, so QR codes and small text stay scannable.
3. Burr-free flat tags: Chemical removal leaves no roll-over burr, so the plate bonds flush to a curved housing.
4. Controlled depth: Etch depth is held to ±10% of thickness, giving uniform paint fill and consistent contrast.
5. Full-sheet consistency: All plates on a sheet etch at the same rate, so colour and depth match across a batch.
6. Artwork-only revisions: etched stainless steel nameplate runs need only a new film per part number, so serial changes and short runs carry no die cost.

Typical Applications

• Equipment rating plates: Model, rating and warning data etched into 1.0 mm 316L for outdoor machinery.
• Control panel overlays: Function labels and window apertures on brushed 304 for industrial consoles.
• Serial and asset tags: Individually numbered plates etched in panels, then serialized during finishing.
• Brand and logo plates: Deep-etched logos with enamel fill for a premium, long-life finish.
• Instrument faceplates: Fine scales, tick marks and units on thin 304 for meters and analyzers.
• Safety and certification labels: Durable warning plates for equipment exported to humid or corrosive sites.

Design Notes & Process Considerations

1. Stroke versus thickness: Keep the narrowest stroke at 0.15 mm or 1.5 × thickness, whichever is larger, or characters etch unevenly.
2. Etch depth callout: State depth for paint-filled graphics, typically 0.05–0.30 mm, and say half-etch or through-cut.
3. Colour fill: Name the enamel system and colour reference; two-pass fill is needed when colours sit closer than 0.4 mm.
4. Finish direction: Specify brushed grain direction and whether the recessed area should be raw or colour-filled.
5. Adhesive and backing: Give liner type, adhesive grade and service temperature when PSA backing is required.
6. Flatness and burr: etched stainless steel nameplate parts bonded to curved housings need flatness per 100 mm and burr-free edges.
