Compare industrial laser marking machines for metals, plastics, glass, ceramics, electronic components and automated production lines. Selection should consider material and coating, mark content, contrast and depth, takt time, machine vision, traceability and line interfaces—not power alone.
Choose a laser route by material and marking goal
The power figures below describe the current product range; they do not guarantee the same color, contrast, depth or adhesion on every material. Final parameters require testing with the actual part and code-quality requirement.
| Laser route | Current product range | Selection boundary |
|---|
| Fiber laser marking | 20 / 30 / 50 W | For permanent identification, codes and general engraving on metals and selected industrial plastics; confirm coating, color, depth and takt time on samples. |
| MOPA laser marking | 30 / 60 / 100 W | For evaluating variable-pulse-width tasks such as stainless-steel color marking, black marking on aluminum and deep engraving; power alone does not determine color stability or depth. |
| UV laser marking | Platform-specific | For heat-sensitive plastics, glass, ceramics, electronics and fine marks; material response, edge quality and takt time still require validation. |
| Green laser marking | Platform-specific | For evaluating highly reflective or heat-sensitive materials; absorption, surface condition and target contrast define the process window. |
| 3D laser marking | Configured to geometry and field size | For parts with height variation, curved surfaces, large fields or deep engraving; evaluate calibration, distortion, focus compensation and motion together. |
Boundaries to confirm before selection
- Define the task first: text, logos, serial numbers, DataMatrix, QR codes, color, black marking, coating removal, engraving or deep engraving.
- Material grade, surface treatment, coating and color change absorption and contrast; one laser source will not produce identical results across every batch.
- Regulated or traceability projects should define code format, size, grade, durability and machine-vision verification—not only whether the mark is visible.
- Inline integration also requires part positioning, triggering, vision, data interfaces, fume extraction, safety interlocks and target takt time.
From sample marking to a traceability system
Review the laser marking process guide, then use sample testing and process validation to submit the material, mark content, quality standard, takt time and code-verification requirement. For equipment, vision or line planning, request sample marking and a configuration review.
Frequently asked questions
How do I choose between fiber, MOPA, UV and green lasers?
Fiber lasers generally cover metals and common industrial identification. MOPA is evaluated for variable pulse width, color or black marking. UV and green lasers can be evaluated for heat-sensitive or specially absorbing materials. Test the actual material and mark goal.
Does higher power always mean faster or better marking?
No. Speed and quality also depend on wavelength, pulse width, frequency, spot size, fill strategy, material absorption, target depth and contrast. Excess energy can increase melting, burrs or heat effects.
How can a QR code or DataMatrix be kept readable?
Define code and cell size, contrast, surface condition, illumination, camera and grading standard, then validate the entire marking-and-reading process on production-like parts.
Can curved parts or parts with height variation be marked?
3D dynamic focusing, fixtures or motion axes can be evaluated, but field size, curvature, height range, distortion and focus compensation must be validated together.
What information is needed for sample testing?
Provide the material and surface treatment, artwork, size and depth, target color or contrast, takt time, code grade, durability requirements and production-line communication conditions.
