Nowadays, there are many types of laser marking machines on the market, and the prices are also high and low. However, the industry has different requirements for marking. We must know our processing materials and effects. According to the specific materials, the type of laser marking machine is selected. Not the same. How can I choose a laser marking machine that is suitable for processing in my own industry?
First, the laser marking machine laser
First, confirm the material of your own product, because different materials absorb different degrees of laser light, and the degree of absorption is determined by the wavelength of the laser. Different laser wavelengths are referred to as different laser sources. Therefore, different laser sources should be chosen for different materials. .
Fiber laser marking machine, wavelength 1064nm, the main application areas: hardware, plastics, label paper.
Co2 laser marking machine (CO2 laser marking machine), wavelength 10. 6μm, mainly used for bamboo, cloth, ceramics, acrylic, leather, etc.
UV laser marking machine (UV laser marking machine), wavelength 355nm, mainly used for thermal materials such as silica gel, UV plastic, paper, glass;
Can I engrave a material with only one laser source?
Of course not, some materials are suitable for various laser sources, but the degree of laser absorption in different bands is different, and the effect depends on the user's acceptance. For example, glass engraving:
Co2 laser marking machine - glass is relatively rough, easy to produce glass slag;
Ultraviolet laser marking machine - cold light source, glass marking is very fine and uniform;
Second, laser marking machine power
Laser power is sometimes the key to speed and performance. Different laser sources have the most stable power range:
The 20W/30W power of the fiber laser marking machine is the most stable.
The 30W power of the CO2 laser marking machine is the most stable.
The 3W/5W power of the UV laser marking machine is the most stable.
The green laser marking machine's 3W/5W power is the most stable.
Choosing the right power depends first on the material of the product, such as UV engraved paper, film and plastic, and can be done using a low power 1.2W mark. If you engrave glass, you need 3W or even 5W of ultraviolet light to engrave.
Second, with regard to efficiency, for example, fiber optic 20W is commonly used to tag hardware. If the efficiency and speed are pursued, the high power of the fiber 30W is of course more efficient.
Of course, depending on the effect and marking time, it is recommended to use a specific sample for testing to determine if the power source you purchased is the most appropriate.
