Coherent CO₂ Laser Marking Machine: Expanded Overview

Building on the previous overview, here's a deeper dive into the Coherent CO₂ Laser Marking Machine, addressing technical specifications, advanced applications, and practical considerations:

The Coherent CO2 Laser Marking Machine is a high-precision industrial laser system designed for permanent marking, engraving, and coding on a wide range of non-metallic materials. Utilizing a gas CO2 laser source (typically 10.6 μm wavelength), it delivers excellent beam quality, high speed, and superior marking clarity.

1. High precision and speed. Marking depth can be controlled easily. Continue working no need maintenance.

2. Imported power source with high speed galvanometer& path expander fans system.stable path fast marking.

3. With good quality F theta lens & galvonometer lens assured a high speed and high precision marking efficiency.

4. Industry computer, strong anti-interference and adaptation stable working position for 24 working.

5. Red position system avoids material waste.

6. Multi-function software with friendly interface support win7/xp/2000/win7/8/10 together with many languages version. Supporting True Type font and single line font JSP, DMF, One-dimensional code and VIN.

7. supporting bmp, jpg, gif, tga, png, tif file together with ai, dxf, dst, plt. Work on 256 level grey image. Image processing for grey conversion, black white conversion and dot.

8. Free control system and outside equipment.

9. Using imported laser source, high quality strong beam energy,focus marking point is small, ultra-fine marking.

10. Small heat affected area. Prevent material deformation, damaged or burnt. High rate of final products.

11. Using digital galvanometers, lower drift, higher positioning speed, higher performance and higher precision.

12. The overall design meets CE requirements.Wide range of applicable materials.

13. With high-speed marking, could fulfill the bulk and production line marking needs.

14. With high power configuration, besides marking, also could engrave and cut on nonmetal materials.

15. Could mark the larger object with big sizes.

16. Longer lifespan, although fiber laser marking machine is very long could be 100,000 hours, the RF CO2 laser marking machine's lifetime is even longer, can be 200,000 – 300,000 hours.

CO2 laser marking machine is currently a laser product with a high continuous output power. It is widely used in the field of non-metallic material cutting, and is used in leather, stone, jade, textile, medical, material processing, industrial manufacturing and other fields, especially in Industries such as logo marking and inkjet printing have unique applications.

. Key Components

Laser Source: A CO2 gas laser emitting infrared light at 10.6 μm wavelength.

Control System: Computer and software for designing marks and controlling parameters (power, speed, frequency).

Galvanometer Scanners: Direct the laser beam rapidly across the material.

Focusing Lens: Concentrates the laser beam for high-resolution marking.

. Working Principle
The CO2 laser generates a beam that interacts with the material's surface, causing vaporization, color change, or chemical alteration. The software translates designs into movement patterns for the scanners, creating marks without physical contact.

. Applications

Industries: Electronics (serial numbers), medical devices (traceability), packaging (barcodes), automotive (part labels).

Materials: Plastics, wood, glass, ceramics, anodized aluminum, leather, and some coated metals.

. Advantages

Precision: High-resolution marks for detailed graphics/text.

Speed: Rapid processing suitable for high-volume production.

Durability: Permanent, wear-resistant marks.

Non-Contact: No tool wear or material deformation.

. Considerations

Material Compatibility: Best for non-metals; metals typically require fiber lasers.

Safety: Requires enclosures, interlocks, and protective eyewear to prevent exposure.

Maintenance: Regular gas replenishment (if sealed tube), optic cleaning, and alignment checks.

1. High marking speed: maximum 7000mm/s marking speed with high-speed galvanometer scanning. Suitable for industrial mass production.

2. Large marking area: Max marking area 600*600mm, can realize marking, punching, cutting, carving process.

3. Good stability of the equipment: Adopted the full closed optical path, imported of CO2 R.F laser source, strict multiple protection control design, ensure the stability of the entire equipment.

4. Red light indicator, makes you find out the working area easily.

Material-Specific Insights

Plastics: Achieves contrast via foaming (light marks) or carbonization (dark marks). Avoid PVC (toxic fumes).

Glass/ceramics: Frosted effects or subsurface engraving without cracking.

Anodized Aluminum: Removes the colored layer to expose the metal underneath.

Organic Materials (wood, leather): Engraves intricate designs with minimal burn marks using pulsed modes.
