When it comes to laser marking machines, most first-time customers find it difficult to pick the right machine for their application. The reason is there are a variety of machines available in the marketplace, each designed with different lasers and materials. The wrong choice can lead to immense expenditure in terms of time, effort, and money. Hence, it is important for first-time buyers to understand certain points when looking for laser marking machines for their facilities.

Points to Consider when Choosing Laser Marking Machines

Apart from some minor considerations, there are six main points that need to be kept in mind when choosing a laser marking machine for your facility. Let us take a look at these points in detail.

Type of Laser: Today, three different laser marking systems are utilized for the most part – CO2 Lasers, Nd:YAG (rod lasers), and Ytterbium (fiber lasers). Rod and fiber laser machines are the popular choices used by most industries, while CO2 lasers are generally used for simpler, personal applications, though this is not always true. All three laser machines are priced similarly, depending on the power output and options.
Type of Material: This is an important factor, as customers have to understand how a particular material absorbs laser light at a certain wavelength. Generally, plastics and organic materials have the ability to absorb high laser wavelengths, above 10,000 nm. Metals in general have an excellent absorption rate up to 1064 nm. This distinction is important, as it will guide the customer to the right laser for their application. Metals will have to be marked with either an Nd:YAG rod laser or a Ytterbium fiber laser. Plastics are marked very well with CO2 lasers, but can be marked with Nd:YAG or fiber lasers depending on the plastic itself.
Pulse Duration: The pulse duration is important, as it affects the amount of laser penetration and depth in a material. Solid state pulsed laser machines are also known as nanosecond (ns) lasers. Depending on the type a customer chooses, the laser machine will be able to achieve a pulse duration ranging from 5 to 200 ns. The pulses can be controlled to be short or long depending on the laser. Short pulses are used for HAZ materials, day-night marking, or other sensitive applications. Long pulses are used for stronger materials, or for more precise marking applications.

Points to Consider when Choosing Laser Marking Machines

The points below provide details about the size and quality of the laser beam, as well as the machines’ marking capabilities.

Marking Quality: While the marking time and depth is easy to quantify, the mark quality will differ with the customer’s requirements. Customers need to consider the resolution, edge quality, line width, HAZs, color contrast, etc. before they decide on a particular laser machine.
Beam Quality: A laser machine’s beam quality is measured by a metric value known as M2. When the M2 value is small, it means that the beam quality is at a high level. A laser beam with an M2 value of 1 is of the highest quality. The beam size can be reduced down to a small spot, while providing high energy density. Also, when the beam quality is high, the chance of it getting out of focus when working with round or uneven materials is decreased.
Mark Field Size: This refers to the area within which the laser marking takes place. The focal length of the laser is directly related to the mark field. If the focal length is long, the mark field will be large, but the power density will drop.

Other Considerations

When using the laser with a higher speed, the frequency should be increased. This will increase the chances for pulses to overlap.
As much as possible, the pulses should overlap with one another. This ensures good edge quality, and a smooth surface after the laser marking procedure has been completed.
The three technologies, Nd:YAG, CO2, and Ytterbium Fiber, provide a variety of benefits to customers. It will also allow customers from the manufacturing sector to perform complete design and manufacturing in-house. If all three technologies are available, customers will have the opportunity to test them, and find the machine that is best suited for their applications.

As we are in the laser business for more than 13 years, we see more and more like to use this technology with their business. And laser machine is suitable for many purposes, one of them is using industrial laser cutting machine to cut metal sheet or metal plates, like stainless steel, aluminum alloy, carbon steel, etc. Why? Because when you use laser to process, it is very accurate and precision, and has a high quality of cut edge and in the meantime, the kerf width stay small, so the laser beam affect very little on the metal itself.
The first thing you need to know about laser is the word itself, LASER is an acronym for Light Amplification by Stimulated Emission of Radiation. This magic amplified light can easy cut metal, it is like sci-fi when we first think of it. But it is real, we are going to show you how?
First thing about this technology is laser beam. It is a high-power light with just one wavelength. Furthermore the wavelength can not be seen by human eye. This column of light is only about 3/4 of an inch in diameter. When the machine is working, laser resonator creates the beam, let it pass through a certain path before it gets to the bore of a nozzle right before it hits the metal sheet and focuses its power on the sheet, along with the beam, there is a compressed gas, such as Oxygen or Nitrogen.
In the laser head, there is a process going on to let the laser beam focused by curved mirror, or a special lens. In order to let the machine work perfect, the path of laser beam must be adjusted over and over again, until you get the beam perfectly focused, that way the density of this laser energy will be consistent and centered in the nozzle. Through the nozzle, it energy of laser beam is being amplified, try to think of the time, when we were kids, we used magnifying lens to catch sun’s power through it, added this power on paper, how fast it can set a fire. Just like that, now think about when you add 8k watts of energy on the metal sheet, you already know what will be happening.
The laser beam with this high power can melt or vaporize metal in the blink of an eye. When we add laser beam on carbon steel or mild steel, we are going on a process called oxy-fuel, and the gas with it, of course, is pure oxygen. When we add it on stainless steel, the gas with it is nitrogen. And by the way, we use high pressure nitrogen to blow molten metal out of the surface, to get this beautiful contour.
When laser cutting machine is working on the metal, it will follow the program that you put in the system, and precisely cut the shape out of the metal sheet. During that process, the laser head is just above the material, with a certain distance controlled by height control system. So between the metal sheet and the laser head (or the end of the nozzle), there will always be a safe distance. It is very important about this distance, it allows the focal point relative to the surface of the metal sheet. The quality of the cutting process can be effected when it comes to different distance.
Of course besides safely distance, when you want the laser machine to work perfectly, there are many technical parameters you need to think about, but once all things set up, you are good to start your own business. Laser technology is widely used in many different business, especially when we are talking about metal fabrication industry. XT LASER industrial laser cutter is suitable for your business.

We will attend the Blech Exhibition in Mumbai,India from 27th to 29th,April.

Ready to have a meeting with you,how about you?

 

 

Those days I feel helpless because many many customers ask me to give them more lower price. Sometimes I feel sad and disappointed because they already gone the wrong direction. So I have to say something for those customers.

When you decide to buy a machine, the first you should consider is not price…

1) First confirm if this machine can satisfy your requests or not. (If you were distributors or you used same machine before, then you can pass the first step.) So how to know if this machine can satisfy your work? It is easy. Tell suppliers, you can tell 4-5 suppliers and ask them to make samples according to your request. After checked their samples, pass 2-3 suppliers. Continue to talk with the better suppliers.

If you need special machine for your production line, so first you need check if this company has such experience before. Better let them provide you the successful cases.

2) Try to know more about machines, different specification, different price. It is not necessary to choose the best specification, just the spec. can satisfy your work. Then it is enough.

3)Talking price. In this step, you must pay attention to specification. Because some suppliers will change the specification if you ask very very lower price. So you’d better tell them basis on same specification, what price they can offer you?

It is an open market, price is not a secret. Also, seller is not stupid. You should know whatever the price you get, seller must have profit more or less. If profit is very less, then they can’t provide you the better service because they don’t have such ability.

Also, with exactly same specification, another company provide you very very lower price, you need careful. They must change something you don’t know to keep their profit point. Maybe wire, maybe machine shell quality etc.. After you got machine, whatever problems you met, how could you do? If they don’t reply your email and don’t pick up your call, what else you can do?

So dear all, pls do not fight with me about price. When I put my heart and want to help you and want to give you a better solution, you only ask lower price, your action will hurt me. I care about every customers whatever they buy or not, for those customers already bought from me, I will keep them find me at anytime.

But pls do not push me to a bad person.

Thank you.

More and more customers are looking for fiber laser machines from China, because of high cost-effectiveness. And Made-in-China is accepted by foreigners.

However, you will get more response than you can imagine, different prices with different machine Spec. Even different prices based on same configuration. Why is that ?

Everybody is considering price,however, how much do you pay attention to quality ? How much do you pay attention to after sales service?

Let’s do a simple math, assume that you can save $500 for one 20w machine, when it breaks down without in-time service, and you are thousands of miles away from China, how much will you lose then?

Here is comment from USA customer’s feedback which was posted on Facebook FYI:

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Our confidence is not just coming from our quality, but also the feedbacks from customers. We would like to share more with you if you like.

However, many customers are suffering a different situation and coming to us for help.

Although we offer solutions for those friends, it made a bad impression on “MADE IN CHINA”, which is very regretful. There are more cheaper prices in China market, however, quality varies a lot.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

We are small compared to all the China Industrial products, however, we are committed to contributing as much as we an. To keep our quality and reputation. In 2 years’ warranty, any part of the machine goes wrong, we offer new by Express (cost on us), and better thing is that we can offer you solutions / answers in 8 working hours.

Please do not get this wrong, there are good companies and bad companies all over the world, this does not mean Made-in-## is bad quality. We, as you do, also like no labels tagged by others. However, those with same taste come together. We do believe Made-in-China will arise with plenty of real manufacturers efforts and Perseverance
