01 · Marking applications

Laser marking categories.

Different marking purposes — branding, traceability, compliance — each with specific requirements for content and durability.

Logo and branding

Customer logos

Customer brand logos laser-marked on parts. Permanent, doesn't wear off, doesn't affect part function. Standard for premium consumer products.

Serial numbers

Unique per part

Sequential or random serial numbers per part. Critical for: warranty tracking, recall management, individual part identification. Often combined with date code.

Lot codes

Production batch ID

Lot or batch identification — date code, shift code, line number. Production tracking, quality investigation.

Barcodes

1D or 2D

UPC, EAN, Code 39, Code 128 barcodes. Standard for inventory management, supply chain tracking.

Data matrix codes

High-density 2D

Data matrix (DPM - Direct Part Marking) codes. Compact 2D code with error correction. Standard for medical UDI, aerospace traceability.

Medical UDI

FDA compliance

Unique Device Identification per FDA UDI rule. Required for medical devices. Specific format with device identifier + production identifier.

Aerospace mark

AS9132 spec

Aerospace direct part marking per AS9132. Specific format and depth requirements for jet engine and structural parts.

Cosmetic engraving

Decorative

Decorative engraving for premium consumer products — watch backs, awards, custom hardware.

Calibration scales

Precision graduations

Precision laser-engraved scales on instruments, measuring tools, calibration hardware.

FAQ

Laser Marking questions.

Fiber laser (most common): steel, stainless steel, aluminum, titanium, brass, copper. Anodized aluminum (great contrast). Excellent for metals. CO2 laser: most plastics (acrylic, ABS, PC, PEEK, Delrin), ceramics, glass, leather. Fiber laser also works on some plastics with proper laser parameters. Specific material/laser combinations tested case-by-case.

Different applications have different depth requirements. Aerospace AS9132: typically 0.05-0.13 mm depth depending on application. Medical UDI: surface marking adequate (anneal mark). Industrial: 0.05-0.1 mm typical. For wear/abrasion environments: deeper (0.2-0.3 mm). For cosmetic: surface anneal (no depth, color change only). Specify depth requirement on drawing.

FDA UDI rule requires medical devices have Unique Device Identification including: Device Identifier (product), Production Identifier (lot, serial, expiration). Format: data matrix code with human-readable text. Direct Part Marking required for reusable medical devices. Our laser marking system supports compliant UDI marking with verification.

Mark verification: verify mark quality and content per applicable standard. AS9132 has specific quality grading (A-F) measured with verifier. Medical UDI verifier per ISO 15415 (data matrix) or ISO 15416 (linear). We perform mark verification per customer specification, document mark quality grade. Inline verifiers can verify each mark in production.

Contrast varies with material and process: Steel/stainless dark mark on light substrate (high contrast). Anodized aluminum: light mark on dark substrate (high contrast — anodize layer removed exposing bright aluminum). Bare aluminum: lower contrast (gray on silver). Plastics: typically dark mark on light substrate. For high contrast on bare aluminum, consider anodize before marking.

High-volume capability — typical mark cycle: 1-15 seconds per part depending on mark complexity. Production: 100s-1000s of parts per shift. For very high volumes, dedicated marking station with automated part loading. Pricing scales with production volume — per-mark cost can be very low at scale.
