What is a Fiber Laser Marking Machine?

Fiber laser marking is a technique of leaving an impression on items with the help of a fiber laser of light.

The marking machine uses concentrated energy from light energy and turns it into a laser beam. This beam passes through an f-theta lens, which helps the light to focus on the whole plain. The concentrated laser beam creates distinct marks when passed over any surface. Note that different material surfaces absorb different wavelengths of light.

How do Fiber Laser Marking Machines Work?

Laser marking machines use a focused beam of light to mark the surface. When the light falls on the item’s surface, it changes the material’s appearance and properties.

This beam targets only a particular surface, allowing the laser marking system to create high-quality, precise, high-contrast marks that are easy to scan or read on virtually any surface. This feature makes machines ideal for applications where permanency and accuracy are important.

2. Non-contact Process

The energy carrier of fiber lasers is a beam of uniform wavelength. It doesn’t generate any mechanical stress while irradiating the surface of any material. This is why it doesn’t affect any mechanical properties of the material you use. It also eradicates noise pollution and chemicals. Therefore, the marks are tidy and clean.

3. High Quality and Precision

A fiber laser engraving machine is a highly precise engraving device. The machine uses high-precision laser technology to offer micro-level accuracy, ensuring accurate and fine engraving results.

Also, the beam output center of the device is 1064nm. The spot pattern of these machines is excellent, and the focused spot diameter is usually around 20um. Apart from that, the single line is thinner, and the divergence angle is 1/4.

Hence, it can offer ultra-fine and precise processing. When it comes to the marking quality of the device, the text information marked by the laser is permanent and clear and will not fall off or fade.

Comparing Different Marking Machines

I. Inkjet Printing Machines

Inkjet printing engrave marks on packaging and products by placing ink on the item’s surface. The inkjet coders virtually print on materials like wire, plastic, cable, metal, paper, glass, resin, and more. Manufacturers use it to print common symbols like lot numbers, dates, serial numbers, date codes, and barcodes. Inkjet printing is different from fiber laser marking machines.

The software present in the coder controls the jet to create print 1D and 2D marks. This allows the company to mark its packaging and products to track items permanently. This is also important to facilitate quick recall when necessary and meet regulatory requirements. Its ability to limit the risk of blurred or smeared printed codes, ensures these codes stay readable throughout the distribution and production process.

II. CO2 Laser Machines

CO2 laser machines use sheet metal processing techniques that utilize an electricity-driven gas laser. It features a laser that cuts contours over different metal sheets such as stainless steel, steel, or aluminum.

This machine offers accurate results and allows you to work on complex designs. Hence, you have a lot of shaping freedom compared to other printing machines. These machines are also one of the oldest printing devices. In fact, its origin is traced back to the 1970s.

This cutter machine generates the laser beam in a sealed glass tube that includes gas like carbon dioxide. When the machines start, a high voltage passes through the tube and reacts with the gas particles, raising their energy that generates light. A particle with a strong light that is heated can be extremely strong enough to vaporize materials with hundreds of degrees Celsius melting points.

III. Green Laser Machines

These machines are made to mark highly reflective surfaces. Green laser machines also work best for highly sensitive substrates such as silicon wafers. It is designed to exhibit exceptional results and high precision. These machines feature 5-10 watts of power range. They are also ideal for soft plastics, integrated circuit chips, and PCB Boards. They are also used for marking or scribing Solar Cells of different material compositions.

Laser Machines

Since the machine uses a 532nm wavelength, it provides greater absorption for different materials. It mitigates thermal energy, allowing the machine to mark substrates you can’t receive from the higher wavelength. Another advantage of this machine is that it can mark tight spot sizes of more than 10 µm.

IV. UV Laser Machines

UV technology uses a band of the electromagnetic spectrum with a wavelength of 10nm to 400 nm. These are longer than X-rays but shorter than visible light. Additionally, long wavelength UV is different from ionizing radiation, as its photons don’t contain energy that can ionize atoms. But it can lead to chemical reactions that make substances fluoresce or glow. Therefore, UV’s biological and chemical effects are more than simple heating.

Also, most of the applications of UV radiation only occur due to its interactions with organic materials. UV laser marking machines are the result of this technology. They come with 355 UV laser wavelengths and can engrave different materials.

You can use them for cold marking applications, which don’t require heat from lasers. This machine can mark substances like glass, plastics, and ceramics without additives. Since they have a high-quality beam, these machines can micro-mark electronic microchips and circuit boards. Many manufacturers also use it for precise medical equipment marking and solar panels.

What to Consider When Choosing a Fiber Laser Machine

Choosing a suitable laser marking machine can make a huge difference to your production. It also determines the profitability of the project. Here are a few factors that you should consider when making your choice.

1. Material Compatibility

The first thing you need to consider is the type of material needed to engrave. There are two types of materials: non organic materials and organic materials. Organic materials are plastics, glass, paper products, and wood. You can use the fiber-cutting machine for both materials.

2. Marking Speed and Precision

The engraving speed is one of the main factors that you need to consider. The speed is directly proportional to the strength of the optical fiber power source. So, the more laser power, the higher the speed you can expect.

This means you need to choose a 30W laser, which can give you a deep engraving depth of 0.3mm with a speed of more than 4000 millimeters per second, offering you great results. Therefore, if you want to engrave at high speeds, you need to look for a fiber-optic laser with 30W. With this machine, you can also expect to get precise results.
