The Science of Permanent Identification

Using fiber lasers, we achieve microscopic marking precision — contact-free, consumable-free, with no change to the part’s dimensional tolerances. Every parameter — power, speed, pulse frequency, and focal distance — is set individually for the material and required contrast. The result is a legible, permanent code or text that lasts as long as the part itself.

Indelible Marking Durability

Laser marking alters the material's surface structure at a molecular level — it does not fade, peel, or wear off over the part's operating life. Resistant to industrial chemicals, oils, solvents, UV radiation, and temperatures up to +350°C on stainless steel and +150°C on aluminium.

High-Precision Detail

Fiber laser marking achieves 0.1 mm resolution, producing legible QR codes and DataMatrix codes on areas smaller than 5×5 mm — ideal for miniaturized components in electronics, medical devices, and precision instruments. Every code is machine-verified for readability per ISO/IEC 15415 after marking.

Zero Mechanical Stress

The laser beam never makes physical contact with the part — no mechanical stress, no surface deformation, no change to dimensional tolerances. This makes the method ideal for heat-treated parts, thin-walled components, and precision parts with tolerances as tight as ±0.01 mm.

Indelible Laser Identification

Advanced Marking Specifications

We tailor every marking project to match your specific material grade and traceability requirements. We ensure optimal contrast and precision for a wide range of industrial applications.

Advanced Serialization

We mark QR codes (ISO 18004), DataMatrix ECC200, GS1-128, Code 39, Code 128, and HIBC codes, with readability verification after every part. Sequential serial numbers, batch identifiers, date codes, and UID numbers are processed automatically from Excel files or ERP exports — every part receives a unique identifier without manual input.

Material-Specific Optimization

Laser power, scan speed, and pulse frequency are optimized individually per material. Black annealed marking on AISI 304/316 stainless steel. High-contrast white marking on anodized aluminium. Deep engraving on brass. Gold anodizing marking on titanium. Dimensional tolerances remain unaffected.

Automated Data Processing

Variable data — serial numbers, barcodes, production dates, batch numbers — is processed directly from structured Excel files or ERP exports. Every component in a batch receives a unique identifier automatically, with no manual re-entry. Capacity: tens of thousands of parts per batch with zero data-entry error rate.

Flexible Production Formats

We mark single prototypes for development teams as well as production-scale batches for manufacturing lines. Parts can be delivered loose, in trays, or arranged on sheets per customer specification. Rush orders and shortened lead times are available on request.

Manufacturing Excellence

Quality Assurance & Standards

Consistent Marking Quality

Every order passes 3-stage inspection: incoming material inspection, in-process contrast and dimensional checks, and outgoing visual and machine code verification. ISO 9001:2015 certification (SGS-verified) is available on request for every order. Production records are archived for 10 years.

Scalable Production Capacity

Every QR code and DataMatrix code is machine-verified for readability immediately after marking. We use GS1-certified verifiers to confirm Grade A/B readability per ISO/IEC 15415. A verification certificate is available to customers on request. Zero tolerance for unreadable or damaged codes.

Indelible Legibility

SITAPRESS provides UDI (Unique Device Identification) laser marking compliant with EU Regulation 2017/745 (MDR) for medical device manufacturers. We mark HIBC and GS1 DataMatrix codes on implants, instruments, and medical device components in stainless steel and titanium.

Custom Configuration

Laser power (W), scan speed (mm/s), pulse frequency (kHz), and pass count are set individually for each material and application. Result: optimal contrast without heat damage to the surrounding area, preserved dimensional tolerances, and intact surface integrity.

Frequently Asked Questions

What materials can be laser marked by SITAPRESS?

SITAPRESS performs laser marking on stainless steel (AISI 304 and AISI 316), aluminium, and brass components. We optimize contrast settings, marking speed, and focal depth for each specific material type to ensure maximum legibility and consistent marking quality. The laser parameters are adapted to each material to achieve a high-contrast permanent mark without damaging the surrounding surface or altering the dimensional tolerances of precision components.

What is the difference between laser marking and laser engraving?

Laser marking modifies the surface properties of the material — through processes such as annealing, oxidation, or surface coloring — to create a permanent high-contrast mark without significant material removal. The surface remains dimensionally unchanged. Laser engraving physically removes material to create a recessed cavity with visible depth. SITAPRESS provides laser marking optimized for permanent industrial identification, traceability, and serialization without compromising the structural integrity or dimensional precision of the marked component.

Can laser marking include QR codes, Data Matrix codes, and sequential serial numbers?

Yes. SITAPRESS specializes in high-precision laser marking of 2D codes including QR codes and Data Matrix codes, sequential serial numbers, batch identifiers, and date codes. Variable data can be processed directly from structured data sources such as Microsoft Excel files, enabling fully automated batch marking where each component receives a unique identifier without manual intervention. This supports complete product traceability from production through the entire service lifecycle.

Is laser marking permanent and resistant to harsh industrial environments?

Yes. Laser markings are permanently bonded to the material surface at the molecular level — they do not fade, peel, flake, or wear off under normal or demanding industrial conditions. Unlike adhesive labels or ink-based marking methods, laser markings withstand prolonged exposure to industrial chemicals, oils, solvents, cleaning agents, UV radiation, high temperatures, and mechanical abrasion. This makes them the preferred identification method for components requiring permanent traceability throughout their entire service life.

What industries use laser marked parts from SITAPRESS?

Laser marked parts from SITAPRESS are used across a wide range of industries where permanent component identification and traceability are required. Key sectors include automotive manufacturing, aerospace and defense, industrial machinery, medical device manufacturing, electronics, oil and gas equipment, food and beverage processing equipment, and pharmaceutical manufacturing. Any industry subject to regulatory traceability requirements — such as CE marking compliance, UDI (Unique Device Identification), or serial number traceability — benefits significantly from laser marked permanent identification.

What is the minimum order and lead time for laser marking?

The minimum order is flexible — SITAPRESS manufactures everything from single prototypes for development teams to serial production batches for manufacturing lines. Standard lead time is 5–10 business days from artwork or drawing approval. Rush production with shortened lead times is available on request. Quotes are always free and non-binding — we respond within 1–3 hours.
