Laser marking machines are innovative coding and marking solutions to mark text, dates, logos, patterns, etc. on products, whether it is to replace inkjet printers or traditional laser printers where they cannot satisfy your needs, or to enhance marked data's durability and identifiability. There is no consumable for laser marking and engraving machines. MEENJET designs and manufactures different types of laser marking machines to address the needs of various applications, including mini laser marking machines that are flexibly portable, desktop laser marking machines that can be used on a table, and fly laser marking machines that are used in production lines. Businesses can buy the best-priced flying laser marking machines at MEENJET factory. The power ranges from 10W, 20W, 30W to 50W and, the laser source choices are CO2 laser, UV laser or fiber laser.
If you already know the principles of laser marking, you can skip this answer.
Laser marking is a precision process that uses a focused laser beam to permanently mark or label a wide range of information, including 1D and 2D barcodes, serial numbers, lot codes, variable-height text, variable date and time, and images. Unlike traditional thermal transfer or inkjet marking methods, laser marking delivers high-resolution results that are permanent and resistant to wear, making it ideal for industries such as automotive, aerospace, electronics, and medical devices.
The process works by directing a concentrated beam of light onto a material’s surface, causing a physical, chemical, or thermal reaction that alters its appearance. The type of reaction depends on the material and laser wavelength. Common laser types used include CO2, UV, and fiber lasers. The laser beam is precisely controlled by specialized software, enabling intricate designs and high-precision markings.
Meenjet laser marking machines can all print text, serial numbers, dates, barcodes, logos, patterns, pictures, DM code, and QR code. You can edit the printing content directly through the printers' touch screen, or import a file from the USB interface.
As for materials the laser marking machines support, we should discuss per model and per laser source. Understanding the printing effect and specialties of different laser marking machines can help pick the suitable one for metal, plastic, wood, leather, stainless steel, aluminum, iron fabric or textile. Here's a cheat sheet when comparing flying CO2, UV and Fiber laser marking machines.
| Feature | CO2 Laser | UV Laser | Fiber Laser |
| Wavelength | 10.6 µm | 355 nm | 1064 nm |
| Marking Material | Non-metallic materials (plastics, glass, wood, rubber, leather, etc.) | Primarily plastics, glass, ceramics, and some metals | Metals, plastics, ceramics, and some composites |
| Marking Process | Heat-based engraving, vaporization, or surface modification | Cold marking (minimal heat) | Heat-based engraving, ablation, or surface hardening |
| Precision | Moderate precision (typically used for larger markings) | Very high precision (ideal for fine, small marks) | High precision (ideal for industrial applications) |
| Marking Speed | Moderate | Slow (due to high precision and complexity) | Fast (high marking speed) |
| Laser Type | Gas laser (CO2 gas) | Solid-state laser (UV wavelength) | Fiber optic laser (solid-state) |
| Beam Quality | Good, but not as fine as UV or Fiber | Extremely fine beam (high resolution) | Good, suitable for high-speed marking |
| Applications | Packaging, textiles, wood engraving, rubber marking, leather, acrylic | Electronics, high-precision components, medical devices, glass etching | Industrial parts, metal engraving, automotive, aerospace, electronics |
| Maintenance | Moderate (due to CO2 tube) | Low maintenance | Low maintenance (durable and reliable) |
| Cost | Lower initial cost | Higher initial cost (due to complexity) | Moderate to high initial cost |
| Cooling | Requires external cooling (water-cooled) | Requires external cooling (water-cooled) | Typically air-cooled or water-cooled depending on power |
| Energy Consumption | Higher energy consumption | Lower energy consumption | Moderate energy consumption |
Low power (less than 10W) handheld and desktop laser marking machines adopting fiber laser source can handle printing on most materials as well. They are suitable for moderate volume productions, and they are affordable for almost every individual or small business.
