Fine permanent detail
Small text, logos and codes can be marked when line width, surface texture and readability are realistic.

Laser Marking for Custom Manufactured Parts
Permanent part identification for logos, serial data, labels, and traceability requirements.

Finish overview
Permanent identification with minimal dimensional impact.
Laser marking is used for logos, part numbers, serial numbers, QR codes, data matrix codes, orientation marks and traceability text. It can be applied to many metals and selected plastics without adding a label, ink layer or significant dimensional buildup.
The result depends on the material, surface finish, coating, mark size, contrast target, readable distance and fixture access. Kewei reviews artwork, location, line weight, code data and inspection requirements before treating the mark as production-ready.
Appearance
What the finished surface can look and feel like.
Material-dependent contrast
Black, white, frosted or color-change effects depend on the substrate and existing finish.
Minimal buildup
Laser marking usually has negligible effect on overall dimensions compared with paint or plating.
Fixture-sensitive placement
Curved faces, recesses and large assemblies need access and focus review.
Suitable processes
Manufacturing routes commonly paired with this finish.
Suitable materials
Base materials that require process-specific review.
Typical applications
Part families commonly reviewed for laser marking.
Serial numbers
QR and data matrix codes
Logos
Part numbers
Orientation marks
Traceability labels
Benefits
Where this option can add value.
- Creates permanent identification without a separate label
- Adds negligible dimensional buildup
- Supports variable data such as serial numbers
- Can be combined with many machined, molded and fabricated part workflows
Limitations
Requirements that need engineering review.
- Contrast depends on material, coating and laser parameters.
- Very small codes may fail readability if surface texture or mark size is unsuitable.
- Some plastics discolor poorly or can be damaged by heat.
- Marking through coatings or on cosmetic faces requires approval samples when appearance matters.

FAQ
Laser Marking questions from engineering and sourcing teams.
Does laser marking change the part size?
It normally has negligible dimensional effect compared with plating or paint. The main concerns are contrast, readability, surface effect and location.
Can QR codes be laser marked?
Yes, but the code size, module size, contrast and inspection method must be realistic for the surface and scanner.
Will laser marking look the same on every material?
No. Mark color and contrast vary with material, coating, texture and laser settings. Critical markings should be sampled or clearly specified.
