Laser marking machines have demonstrated strong application potential in multiple fields due to their high precision, non-contact processing, and wide applicability
1. Industrial manufacturing field
-Metal processing: used for permanent marking of hardware tools, automotive and motorcycle accessories, electronic components (such as serial numbers, QR codes), supporting materials such as stainless steel and aluminum alloy.
-Non metallic processing: Suitable for carving fine patterns on materials such as plastic, leather, wood, etc., such as packaging boxes, craft gifts, and leather products.
-Precision components: Marking small parts in aerospace, medical equipment and other scenarios to meet high-precision requirements (such as fiber laser marking machines that can achieve micrometer level accuracy).
2. Electronics and Semiconductor Industry
-Chip/PCB board marking: UV laser marking machine can achieve ultra fine marking on mobile phone screens and optical components, with minimal heat affected zone.
-Anti counterfeiting label: Enhance product anti-counterfeiting capabilities through irreversible permanent markings (such as invisible QR codes).
3. Consumer goods and packaging industry
-* * Food/drug packaging * *: CO2 laser marking machine prints production date, shelf life and other information at high speed on paper boxes and glass bottles.
-Luxury goods and jewelry: Green laser marking machine carves complex patterns on glass and crystal surfaces to maintain material aesthetics.
4. Special material handling
-Ceramics and hard brittle materials: Ultra fast laser marking machine (picosecond level) achieves crack free cutting and marking.
-* * Film/Coating Removal * *: Used for ink removal or fine processing of coatings on the surface of electronic components.
The outstanding features of laser marking machine
Technical performance advantages
| Characteristics | Description |
| The light spot can reach the micrometer level, suitable for ultra-fine processing (such as ultraviolet laser marking machine focusing on extremely small light spots) |
Permanent Marking | Marking is achieved through material vaporization or chemical reaction, which is wear-resistant, corrosion-resistant, and not easily tampered with |
| Non contact processing | No mechanical stress, avoiding material deformation, especially suitable for fragile or micro workpieces |
| High speed and efficient | The CO2 laser marking machine can reach a speed of several meters per second and supports large-scale production |
Economic and environmental characteristics
-Low operating cost: The electro-optical conversion efficiency of the fiber laser marking machine is as high as 28%, and the energy consumption is only 10% -20% of traditional equipment.
-* * Consumables free * *: No need for ink or chemical reagents, reducing pollution and consumable replacement costs.
-* * Long lifespan * *: The lifespan of fiber lasers can reach 100000 hours, and the maintenance cycle of semiconductor lasers is long (such as end pumped YAG lasers that do not require frequent lamp replacement).
Flexibility and adaptability
-Multi material compatibility: covering metal (fiber optic), non-metal (CO2), special materials (UV/green light), etc.
-* * Programmable Control * *: Quickly adjust patterns and text through a computer, supporting complex graphics and dynamic data (such as real-time serial number generation).
-* * Customized solution * *: Specialized models can be optimized for specific industry needs, such as Dazu Laser's picosecond equipment used for ceramic drilling.
Core comparison of different models
| Type | Wavelength | Applicable Materials | Advantages | Limitations |
| Fiber laser marking machine | 1064nm | Metal and some plastics | Long lifespan, low energy consumption, small light spot | Limited non-metallic processing capability |
| CO2 laser marking machine | 10.6 μ m | Non metallic (wood, plastic) | Low cost, fast speed | Unable to process metal, low accuracy |
| UV laser marking machine | 266nm/355nm | Glass, ceramics, polymers | Ultra fine processing, minimal heat affected zone | High equipment cost |
| Green laser marking machine | 532nm | Glass, semiconductor | Suitable for transparent materials, good beam quality | Narrow application range |
Summary:
The laser marking machine achieves full scene coverage from industrial manufacturing to consumer goods through the combination of lasers with different wavelengths. Its high precision, permanent marking, and low operating cost make it the preferred technology to replace traditional mechanical processing and ink printing. In the future, with the development of ultrafast laser technology, its applications in microelectronics, biomedicine and other fields will be further expanded.
