The Science of Permanent Identification

Laser marking is applied directly onto the component surface, creating precise and durable results. This contact-free process ensures permanent identification without mechanical stress or the use of consumables.

Indelible Marking Durability

Markings are permanent and do not fade, peel, or wear off, ensuring lifetime legibility for critical tracking.

High-Precision Detail

Capable of rendering fine text, small symbols, and machine-readable codes with excellent accuracy and edge definition.

Zero Mechanical Stress

The contact-free process ensures no physical deformation or stress is applied to the part, preserving its structural integrity.

Indelible Laser Identification

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.
