UV Laser Markers
UV laser marking machines use a 355 nm ultraviolet laser to mark and engrave various materials. The laser featured in this type of machine only has around a third of the wavelength of standard laser marking machines.
Due to their shorter wavelength, they are primarily used for ultra-fine marking, mostly on non-metal materials. Read on to find out more about UV laser markers and their applications across various industries.
How do UV laser markers work?
Because of its short wavelength, UV lasers are also known as third-harmonic generation lasers. The machine contains two distinct crystals that the laser needs to go through in order to reach a wavelength of 355 nm. After going through the first nonlinear crystal, its wavelength gets reduced from 1064 nm to 532 nm. The second crystal it goes through further reduces the wavelength to 355 nm.
Unlike lasers that operate at a longer wavelength, UV laser markers don’t cause any heat damage to the material its used on. The process of operating a UV laser marking machine is referred to as cold processing. This means that the machine breaks bonds between atoms or molecules in the material its used on by shooting high-energy photons in the ultraviolet spectrum. Once the bonds are broken, the molecules evaporate.
If you decide to get a UV laser marker in South Africa, you’ll receive a machine with stable output optical power, a fine light spot, and uniform laser power density. You have the option to choose between a manual and automatic working mode. That means that you can optimise your manufacturing process by putting a UV laser to work while you focus on other things.
The benefits of using a UV laser marking machine
Many manufacturing companies turn to UV laser markers when they want to invest in their business and boost the efficiency of their daily operations. There’s a good reason why most business owners in this field opt for UV laser marking machines. Here are some of the main benefits you get from using them:
- The cold processing technology featured in a UV laser makes it a great solution for anyone who wants to mark or engrave various products without worrying about heat damage.
- There are many applications of a UV laser marking machine. It can be used on a range of materials, from wood to glass.
- This type of machine requires minimal maintenance and can remain in top condition for a really long time.
- When you order a UV laser marker, you will receive an integrated safety shutter to help you avoid injuries at the workplace.
UV laser marker applications
UV laser markers can be used to mark (and in some cases engrave) a wide range of materials, including some metals. Nevertheless, if you plan to use a laser marking machine primarily to mark metals, it’s recommended that you take a look at some of the more powerful machines available on our website.
Even though they’re the perfect solution for a lot of different materials, UV laser marking machines aren’t powerful enough to mark certain metals. That’s why it’s best to use them on the following materials:
Considering the large array of materials this technology can be used on, you can see that UV laser marking machines can be used in many different industries.
Our UV laser marker range
On the MaxLaser website, you can find three different models of the MAX-UV laser marking machine series. Regardless of which model you decide to buy, it will come with a marking field of 100×100 mm, a marking speed of 14000 mm/s, and a laser wavelength of 355 nm.
The main difference in these three models is their laser power. You should choose the laser power depending on the materials you want to use the machine on. For ultra-fine marking, it’s recommended that you choose the MAX-UV-5D, which comes with a laser power of 5 watts.
If you’re looking for more power, we recommend the MAX-UV-10D that has a laser power of 10 watts. The perfect balance between these two models is the MAX-UV-15D that comes with a laser power of 15 watts which marks the materials at faster speeds.
Max Laser has a wide range of laser markers
UV laser marking machines can have various applications, but they don’t provide good results in some industries. Nevertheless, you can find the right laser marker on our website regardless of the industry you are in. Here are some of the products that Max Laser offers:
- MOPA lasers – MOPA lasers are a great option if you’re looking to mark metals like gold, platinum, silver, steel, and aluminium.
- Green lasers – Green lasers were created for the purpose of marking thermal-sensitive and highly reflective materials, like glass and plastics.
- Fibre laser marking machines – In case you’re looking for a machine that will allow you to mark both on plastics and metals, you should order a fibre laser marker.
- CO2 laser marking machines – Similar to UV lasers, CO2 marking machines provide the best results when used on non-metal materials like rubber, wood, glass and paper.
