Laser marking is the most common marking method in nowadays, and it's a tendency among all major manufacturing industries. With constant development and improvement, the application range of laser marking machines is expanding, and the requirements they can meet are also increasing. CO2 laser marking can be applied to non-metals, including heat transfer vinyls, high density vinyls, plastics, silicon wafers, ceramics, and rubber. It can be used for small formats (500*500mm) or large formats (1200*1200mm).
For CO2 laser marking machine, it uses a 10640μm laser wavelength. However, the laser power of CO2 marking is relatively low. Large format laser marking machines typically have a power of 250W, 300W, or 350W. This type of machine is called a large format marking machine because it's not only suitable for working sizes from 500*500 to 600*600mm, but also for sizes from 500*500 to 750*750mm, and even for sizes from 500*500 to 1200*1200mm.
Large format dynamic focusing laser marking machines are suitable for marking, engraving, hollowing, and cutting of most non-metallic materials, such as vinyl, leather, fabric, wood, bamboo, paper, and other organic materials. The large format laser marking machine's worktable can handle work targets up to 1200*1200mm, meeting user demands for high speed and high precision. With a maximum engraving speed of 10,000mm/s, it's suitable for industrial mass production, significantly improving work efficiency.
What are the benefits of using lasers for sample marking? Why are people constantly developing various types of laser marking machines to meet diverse needs?
1. Permanence:
For example, the marking will not fade due to environmental factors (such as touch, acid and alkali, high or low temperatures).
2. Anti-counterfeiting:
Laser markings are difficult to copy or alter, therefore it is with good anti-counterfeiting.
3. Non-contact:
Laser marking adopts a non-mechanical processing, allowing it to mark any regular or irregular surface. The marking process does not generate internal stress in the workpiece, ensuring the original precision of the workpiece. It also does not corrode the workpiece surface or cause tool wear. Moreover, it is non-toxic and pollution-free.
4. Wide Applicability:
CO2 laser marking can be used to process a variety of non-metallic materials, especially in garment accessories, garment printing or shoe accessories industry, the laser marking is widely used.
5. High Engraving Precision:
CO2 laser marking machines get fine engraving or cutting result, with a minimum line width of 0.2mm. The markings are clear, durable, and beautiful. Laser marking can meet the needs of printing large amounts of data on even the smallest working area. For example, it can print 2D barcodes requiring higher precision and clarity, making it more competitive in the market compared to embossing or DTF printing.
6. Low Operating Costs:
Marking is fast, and the mark is formed in one go, consuming less energy, resulting in low operating costs.
7. High Processing Efficiency:
The marking process can be completed in seconds, with only one click in the programmed software.
8. Fast Development:
Thanks to the integration of laser and computer technology, users can achieve laser printing output simply by programming on a computer, and can change the print design at any time, fundamentally replacing the traditional mold-making process.
Compared to traditional methods such as mechanical engraving, chemical etching, screen printing, and ink printing, laser marking characterizes low cost, high flexibility, and computer control. What's more, its most notable feature is the durable and permanent mark created by the laser on the workpiece surface.
Currently, laser marking accounts for over 90% of the market share in the marking and printing industry. Therefore, whether it is a large format dynamic focusing laser marking machine or normal CO2 laser marking machine, they are a symbol of the progress of modern society and a breakthrough in the laser industry.
