Industrial Laser Marking Machine Manufacturer & Supplier | Fiber, CO₂ & UV
Laser Marking Machine Solutions
KEYI Laser provides different laser marking technologies for different materials and applications.
Stainless steel, carbon steel, aluminum, copper, brass, titanium, anodized surfaces, coated metals, and most engineering plastics.
Serial numbers, QR codes, barcodes, logos, part IDs, traceability marks, and metal engraving.
For color marking on stainless steel, high-contrast black marks on anodized aluminum, or finer surface control on sensitive materials, MOPA fiber lasers are worth considering.
How to Choose the Right Laser Marking Machine
Start here. Metals such as stainless steel, aluminum, copper and titanium usually need a fiber laser. Wood, acrylic, leather, paper and packaging materials are better matched to CO₂. Glass, ceramics, electronics and heat-sensitive plastics often require UV.
Surface marking, deep engraving, annealing, color marking, high-contrast marking, QR codes or fine graphics all affect the laser source, power, lens and marking parameters.
The marking field should match the part. Standard galvo systems often use a 110×110 mm field, with larger fields, rotary fixtures or positioning systems available for bigger or cylindrical parts.
Low-volume or flexible jobs can use a desktop or portable unit. High-volume production may need a faster galvo system, conveyor integration, rotary devices or automated marking.
Key Features of Industrial Laser Marking
Permanent, traceable marks
Laser marking produces durable identification that withstands handling and environmental exposure — ideal for serial numbers, QR codes, barcodes, and part traceability.
High precision
The focused beam marks fine text, small graphics and high-density codes accurately, especially on electronic components, precision parts and small industrial products.
High-speed processing
Laser marking handles batch production and automated lines efficiently. Actual speed depends on material, marking content, laser source, power and required quality.
Low consumables and digital control
Unlike ink-based systems, laser marking requires no ink or chemical agents. Marking content — text, logos, serial numbers, barcodes, QR codes and variable data — can be created and changed directly in the control software.
Industrial Applications
- Automotive components — serial numbers, part numbers, QR codes, logos and traceability marks
- Electronics & electrical products — fine marks on components, connectors, housings and electrical parts
- Hardware & tools — logos, model numbers, specifications and serial numbers
- Machinery & industrial parts — bearings, valves, metal parts and machine components
- Medical devices — identification and traceability codes on suitable materials
- Packaging & consumer products — marking on selected packaging, plastics, glass and consumer goods

FAQ
Q: What materials can a laser marking machine mark?
A: Laser marking machines can mark metals, plastics, glass, ceramics, wood, leather, rubber, paper and packaging materials. The suitable laser type depends on the material and required marking effect.
Q: Which laser is best for metal marking?
A: Fiber laser marking machines are the standard choice for metals such as stainless steel, carbon steel, aluminum, copper, brass and titanium. They offer high precision, stable performance and low maintenance.
Q: Which laser is suitable for plastic marking?
A: Plastic marking depends on the plastic type and required effect. Fiber lasers work for many engineering plastics, CO₂ lasers suit some organic plastics and packaging, and UV lasers are preferred for heat-sensitive or high-contrast plastic marking.
Q: What is the difference between fiber, CO₂ and UV laser marking?
A: Fiber lasers mainly mark metals and many engineering plastics. CO₂ lasers are used for non-metallic materials such as wood, acrylic, leather, paper and packaging. UV lasers use a shorter wavelength and are suitable for fine, low-heat marking on glass, ceramics, electronics and heat-sensitive materials.
Q: Can a laser marking machine mark QR codes and barcodes?
A: Yes. Laser marking machines can mark permanent QR codes, barcodes, serial numbers, logos and other variable data.
Q: Can KEYI customize a laser marking machine?
A: Yes. Configurations can be adapted to material, workpiece size, marking requirements, production volume and automation needs.
Q: How do I choose the right laser marking machine?
A: Start with material, marking effect, workpiece size, production volume and automation level. KEYI’s team can recommend a suitable configuration based on your application.
