Choosing laser marking machine is the same as what we usually buy. The best is not necessarily the most expensive, and the most expensive is not necessarily the most suitable laser marker.
1.Laser Source
Important factor for the laser marking machine
First, confirm the material of your product, because different materials absorb lasers to different degrees, and the degree of light absorption is determined by the wavelength of the laser. Different laser wavelengths are named different laser sources. And honestly, for different materials, you must choose different laser sources.
- Fiber laser marking machine, wavelength 1064nm, are mainly applied in the fields: hardware, plastic, label paper, etc.;
- Carbon dioxide laser marking machine (CO2 laser marking machine), wavelength 10.6μm, are widely applied in the fields: bamboo, cloth, ceramics, acrylic, leather, etc.;
- Ultraviolet laser marking machine (UV laser marking machine), wavelength 355nm, are mainly applied in the following fields: Silicone, UV plastic, paper, glass and other heat-sensitive materials;
- Green laser marking machine with a wavelength of 532nm, are generally applied in the fields: Film, fruit, eggs, cartons, strengthened glass and other heat-sensitive materials.
Is it possible to use only one laser source to engrave a material?
Of course not. Some materials are suitable for multiple laser sources, but the degree of laser absorption in different wavelength bands is different. And whether the effect presented is good or bad depends on the user’s acceptance. For example, glass engraving is like this:
- Carbon dioxide laser marking machine-glass is rough and easy to produce glass slag;
- UV laser marking machine-cold light source, glass marking is very fine and uniform;
- Green laser marking machine-glass engraving, internal plane engraving.
HJZ LASER reminds you:
To determine what laser is suitable for your product, you need to test specific samples, to see the final effect. The point is: Sample proofing! Sample Proofing! Sample Proofing!
2.The power of Laser marking machine
Laser power is sometimes the key to determine the speed and effect. Different laser sources have a most stable power range:
- 20W/30W Fiber laser marking machine is the most stable;
- The 30W CO2 laser marking machine is the most suitable.
- 3W/5W ultraviolet laser marking machine is the most appropriate.
- The 3W/5W green laser marking machine is the most stable.
Choosing laser marking machine according to the material of the product first. For UV engraving paper, film, and plastic, low-power 1.2W marker can also be used. As of engraving glass requires UV 3W, or even 5W power can be engraved.
The second point of view is the efficiency. For example, hardware is generally marked with 20W optical fiber. If efficiency and speed are pursued, using 30W optical fiber laser marker with high power is of course more efficient.
Of course, to determine whether the power purchased by yourself is the most suitable. It is recommended to test with specific samples, depending on the effect and the marking time.
Besides the laser source and the power of the laser marking machine, the following factors are also important about how to select a best laser marking machine:
The hardware configuration, the origin , the price, the life and stability, Product appearance and brands, after sales service and the customization.
