How to mark different colors on stainless steel-Ariel

How to mark different colors on stainless steel

Most of  customers asked to us how to mark different colors on stainless steel by fiber laser marking machine.Today we will talk about it.

For fiber laser marking machine ,you can mark black, white and golden color easily.

 

1.When marking black color, leave the focus above or under the marking face, decrease the laser power to 80% and increase the speed under 100mm/s.

2.When marking white color, leave the focus above or under the marking face,increase the laser power to 40% and decrease the speed under 1400mm/s.

3.When marking face on focus, you can get golden color.

Of course, these area similar parameter, you need test it around them.

As for other colors, this machine also could do it, but it’s hard and we need to test with your material.

In general, It can mark white, gold, and black color on stainless steel and carbon steel. It only can mark color on high quality stainless steel, just like 304.

If you want to mark color, pls better tell us your stainless steel number. We will make detailed parameter for you in advance. Then after you got machine, all will be convenient.

Hope it is helpful for you,if you have any questions of machine ,welcome to contact to us.

laser marking machine working effects-Wendy

Metal Fiber laser marking machine working effects.

It becoming more and more application now. Especially on metal product, such as stainless steel, carbon steel, aluminum, brass etc.

In order to meet different process demand, metal fiber laser engraving machine also many different application, including color marking, deep engraving, rotary marking etc.

Color Laser Marking

Metal Fiber laser engraving machine can do simple color on stainless steel, such as red, blue, black, white, pink etc. Also it can do black color on Ti, and mopa fiber laser marking machine can do black on anodized aluminum. But for other material, we can only do ordinary marking one white color. It is not possible to do more color.

how to choose mopa fiber laser marking machine

Deep engraving

Also there is many customers use fiber laser engraving machine on deep engraving. The metal is more soft, it is more easy to do deep engraving.

For aluminum and brass, it is easy to do depth. With 30w fiber laser engraving machine we can make more than 1mm depth. Due to carbon steel and stainless steel is very hard, it will take much more long time when we need do deep engraving. Usually 0.5mm is ok for 30w laser.

When we do deep engraving, we need copy two layer. The first layer is low speed and high power so that we can strip the metal material. The second layer is high speed with low power so that we can clean the small slag when do deep engraving.

Due to deep engraving need break the surface of material, so the engraving surface will be rust after some time. So only for some metal parts or mold, people will do deep engraving. Near no people do it on stainless steel.

deep laser engraving

Fiber laser marking machine also have many other application such as jewelry cutting, black marking etc. We will introduce more common application in the future.

Fiber laser color marking used for Titanium-Sophia

Fiber laser color marking used for Titanium

The technique of color marking has been applied across jewellery, metal work and consumer product sectors.

Manufacturers are greatly interested in this process, looking for new methods and finishes to provide product customisation. Brass is one of the few materials, along with Stainless Steel and Titanium.

And that can be colour marked and a select few colours can be marked with very high contrast.

Then titanium is used within the aerospace, medical and jewellery industries. Due to the material being lightweight, strong and highly resistant to corrosion.

In addition, color marking of titanium is most commonly used in jewellery applications. As using a laser allows for a permanent mark which is biocompatible and can also mark three-dimensional surfaces.

The challenge with titanium marking is to generate a high contrast mark whilst causing minimal thermal damage to the surrounding surface and also achieve a wide colour spectrum.

By controlling pulse duration, with variations of high frequency and low scanning speed, the user is able to achieve high quality colour marking.

Thermal management defines the colour of the mark on the material.  And varying the pulse frequency defines the intensity and contrast of the colour.

Depending on the grade of titanium, certain shades of red (magenta) and blue (cyan) are very easy to mark with very high quality.

What should importer do to when purchase laser machine from China?–Winnie

What should importer do to when purchase laser machine from China?

Most of people will feel confused when they plan to import machine or laser machine from China because they always get big different prices even on same specifications. So what should I do when I facing so many suppliers?

Now I give you several suggestions, anyway I think it will help you more or less.

1.Each company has their main products. In general, suppliers always have more experiences on their main products. First confirm what kind of machine you are looking for. Then sure if this machine exactly suppliers’ main products. The question is how to confirm a supplier’s main product?

# Check their official website. China suppliers prefer to putting their main products (machines) on their website main page. So if you see the machine you are looking for on their main page. Then you can follow the next steps.

# Check the main products information. If information is complete and professional, okay, you can consider to contact them to check their service.

  1. Many people also will doubt “are you trading company?” or “are you manufacturer?” The difference between trading company and manufacturer is that manufacturer always will give more lower price than trading company and the service of manufacturer is more timely than trading company. So how to tell them?

To be honest, sometimes it’s very hard to tell them. Maybe the effective way is that let them provide you machine photos in factory( not photos processed by Photoshop), you can pay attention to the background of photos.

Another way, let them make a sample for you. If they are a good manufacturer, they always can provide you samples special for you timely. As for trading company, they have to contact manufacturer first, in general, will slower than manufacturer.

Today I will show you more details when you plan to import fiber laser marker from China. First you need confirm fiber laser markers can satisfy your work. Then compare the specification.

1) Laser source is the core spare part of fiber laser marker. Someone asked “why laser source is so important?”

Fiber laser marking machine, small size, no wearing part, free maintenance, high speed, high precision etc., it seems it is a perfect machine. But no, laser source decides the working time of machine. Some suppliers say you can use machine reach up to 10 years, 20 years. In fact, if your laser source broken at the second year, then maybe you need change a new machine.

Another reason, at first, to satisfy your work, you need set machine power at 50%. After 2-3 years, laser source will weaker than before, maybe you need set power at 70%. One day, you find you set 100% power, then still can’t satisfy your work. So it also means you need change laser source. You must meet such condition, “you told supplier your 20W price is higher, then they only replied you choose 10W” and didn’t tell you anything. So they are just want to selling, they didn’t care your work, your future. Whatever you buy, you need know this machine can satisfy your work perfectly before you buying. Well, now 10w already out of stock.

Popular brands in market is Germany IPG, China Raycus, China Max photonics, (you also will see UK SPI, but use very less in laser marker). To be honest, some suppliers maybe provide copy IPG, Raycus to get a lower price to attract customers. You need careful.

IPG>Raycus>Max Photonics

IPG laser source: (better quality, better beam quality)

the appearance of IPG just like the photo shows. Besides, each real version IPG has sole certification(3 pages), you’d better ask supplier provide for you in advance to ensure they deliveried real version IPG before. The important is the speed they provide you those certification. If after 2 days, they still no any information. Okay, give up.

Raycus Laser Source: (stable quality)

This is Raycus brand laser source. But they launched  a new laser source with red color. It is also real Raycus. You needn’t worry. red color Raycus only uses in 2016 new year, now already stopped.

If they also copy, maybe you can tell from the appearance. Just remember not choosing the lowest price you got from many suppliers.

MaxPhotonics laser source: (very common)

Black color, this is Max. Max is not very stable. Considering laser source is the core part of laser marker, so you’d better not choose Max. 20W Max and 20W Raycus, price difference is not much.

2) Galvo head

Popular brands includes Germany Scanlab, Germany Raylase, China Beijing Sunny brand and Beijing Sino brand.

Very important: copy version Scanlab is verrrrry common in China market. If I were customer, I won’t choose Scanlab in China market. In fact, Real version Germany Scanlab is very expensive, cost is USD6200(original imported) and USD4000(imported mirrors, installed in China). Any other cheaper than this, copy version. (price is only for reference, maybe it will change time by time.)

China Sunny brand Galvo head is good. Head is big and with black color. More cost-effective than Scanlab. As my pinion.

Sino galvo head also is fine. Cheaper than Sunny brand. But if you don’t compare the marking result by magnifier. You can’t see the difference. Besides, the speed of Sunny galvo head is faster than sino brand, If you need fly marking machine and have strict requirement for speed, then choose Sunny brand. <I will upload photos when I have free time.>

3) F-theta lens

As I know, wavelength brand F-theta lens is good. It’s from singapore, also has factory in China, nanjing city.

4) Control system.

Now in market, 2 control systems are popular. The first one, Beijing JCZ control system, EZCAD software. Performance better, convenient to control, and it support English, Chinese, Japanese, and Korean languages for now. Supported format includes PLT, DXF, AI, BMP, JPG, DST, DWG etc..

Second, Samlight software. It’s from Germany. So price is higher than EZCAD. In market, less people choose it because add one more function, you need pay for that. For example, basic price only includes basic function. Sometimes, you want “rotary axis” function, you have to pay extra money for that. So if you choose this software, you’d better ask clearly for suppliers.

Besides those 4 parts, they are still several details, just like worktable, rotary axis, computer etc., you also can compare those details to know which one is the better supplier.

The last, ask supplier copy machine parameters in your computer. In general, supplier will test machine and adjust parameters well before delivery. Better supplier will keep one copy in your computer, someone not. So better remind them.

If you still have any confusion, pls feel free to tell me. I’d like to help people get the satisfied machine.

How to mark color on stainless steel,stainless steel color marking-Jill

How to mark black and white on stainless steel

Stainless steel color marking:We have many customers want to mark color on stainless steel.As we know,Mopa can mark many color on stainless steel.But Mopa is a little expensive.How about Raycus and IPG laser machine?

For Marking different color on stainless steel,normal Q-Switched laser source can also mark color on SS

here is video:  https://youtu.be/hSxRlBQVmh0

Stainless steel color marking,How to set the parameters?

1.Mark black on stainless steel

For example,we use the 20w machine with 100mm lens

Offset-focus, power 80%,speed 80-110,filling 0.02-0.03,the concept of offset-focus is raising and falling down the pillar, until can not hear the sound of the laser marking and can not see the spark of the laser marking, but still have the light burning on stainless steel, it is the most appropriate position.

2.Mark white on stainless steel

marking on the focus point, power 20-30%, speed 1000-1200, fillling 0.05-0.08, frequency 30KHz.

stainless steel color marking

stainless steel color marking

3.Mark other color on stainless steel

For Raycus,black and white color easy be marked on Stainless steel, we only adjust data in software according to the machine and computer.For other color,Raycus can also achieve,but the parameter is a little difficult to set.

 

How about the marking speed?

According to our experience,generally,white color marking speed is faster than black color.

 

How about Mopa

MOPA fiber laser machine can mark different color on stainless steel more easily than Normal Q-Switched laser source,.

The Primary Products of XT Laser (II laser marking)—Tony

The Primary Products of XT Laser(II)

Laser Marking Machine

Classification

The last chapter we talked about three laser marking machine’s difference. Now, we are going to talk about some detail laser marking machine. If you have seen our website or our products of pamphlet. You will see many different laser marking machines.

The model is different. How about the function?  Actually the functions are the same. We made the different model, because base on the customer’s working space and working standard. Some places, in this world, has their own standard for safety. So we put a cover on it.   Some customers want to set the machine on his table, but someone wants to have a desktop. It is all depends on customer’s requirement. Except machines with protective cover, the rest of machines are able to do flying marking.

Power

The different power will change the machine’s efficiency. In theory, the speed of machine marking will increase by enhance of the power. For all kinds of metal, fiber laser marking machine will mark 0.01mm is the maximum depth once time. But if you want deeper or even engrave or cut, the machine will let the light repeat on the materials. Thus the power is higher, the speed of repeat is higher as well. If you look at the machine’s appearance, you can not figure out the power. Because the only change is the laser source. However, we put the laser source in the machine body. You have to open it and see the difference.

Working Area

We provide three kinds of workbench size now, 100*100mm, 200*200mm,300*300mm. It is depends on how big the material is. For marking effect, those three working area are the same. But, because of the laser is a kind of light, it has focal length. So If you want to engrave or cut something big. I advise you send us your materials to check how is the effect. Because the laser’s power will decrease by length. Or you can choose flying marking to handle this issue. XT Laser will set up the parameter for you. We have a strong team for technique support. And we also have a rotary part, if you need to mark rings.

The next chapter I will provide more knowledge for laser marking machines.

MOPA fiber laser marking machine for color marking – Alex

Fiber laser marking machine have very wide application, include color marking. We know it can be used on all metal marking, such as stainless steel, mild steel. Also include painted material and some plastic. Recent years, with the development of fiber laser technology, one new kind fiber laser type rise—— mopa laser color fiber laser marker.

how to choose mopa fiber laser marking machine

Color Fiber Laser Marker

We know normal laser generator is q-switched structure. It have fixed pulse width. Color fiber laser marker need use mopa fiber laser source. It is one special fiber laser technology, which pulse width is adjusted.

We can adjust laser generator’s pulse width and frequency, so that laser generator can have different performance. This is why mopa fiber laser marker can mark color on stainless steel.

What material we can do ?

Mopa fiber laser can mark colors, but not means it can do it on all metals. Now mopa laser can only mark color on stainless steel, no any other material.

Same as normal fiber laser, mopa laser can do all same work, and it have more wide application. Also it have some advantage then normal laser. We know plastic is complex and not easy on laser marking. Due to mopa laser have adjustable pulse width, it have wide application on plastic marking then normal laser.

Except plastic and color marking, mopa laser also can do black color on anodized aluminum. Now so many product is anodized aluminum, such as phone case, mobile power etc.

What color we can mark?

Although mopa laser can do color on stainless steel, it does’t mean it can do all color. Mopa laser can only do simple color like blue, green, pink, purple etc. As for other complex color, mopa laser also can’t do it.

If you want to learn more about laser machine, we can talk more.

laser colors on Stainless steel material through laser technology–Max

laser colors on Stainless steel material through laser technology

The thin-film interference principle of light through laser technology

hands-on workshop
We saw the exquisite samples and said the advantages and principles of laser coloring. What kind of brilliant colors can be produced with lasers?
Let’s look at the experiment.
Test model:XTL-FP20
Short-pulse fiber laser which is with high average power (20 to 100w), Peak power (less than or equal to 15kW) and 2 to 350ns multiple pulse widths are adjustable. So high repetition frequency (10 to 1000khz) can accurately control the laser energy output by using different pulse width, frequency and power combination. Therefore, the surface of stainless steel and titanium alloy can form “oxide film” . And that oxide film consists different thickness and different oxides. Thus it can present different colors that our eyes can see. The advantage is
1. its pulse width and frequency are independently adjustable
2. adjusting one of them will not affect other laser parameters
3. this feature has unlimited possibilities for stainless steel color marking.
Linear frequency – power – pulse width curve
Because the color of stainless steel surface is very sensitive to the change of laser power, if different lasers want to mark the same color, there is a high requirement for the linearity of power-frequency of laser. We have shown the linear curve of related frequency-power-pulse width in this experiment in the figure above.Before the corresponding cutoff frequency of each pulse width, power and frequency show a direct proportion relationship, and a good linear relationship provides a good basis for different lasers to mark the same color.

the time to witness the miracle

The following is the color category by different combinations of process parameters in this experiment:
At present, the laser marking application in China has been used by increasingly manufacturers. Farewell general laser marking only black, white, and grey, based on the expansion of the field of stainless steel marking, a new process of stainless color marking appeared. Only a few minutes, the stainless-steel surface can have a variety of beautiful patterns, not only improve the aesthetic value, but also provides more possibilities for the application of stainless steel in life, and create another era of laser marking.

By the way, we are looking for partners and distributors of laser marking, cutting, welding and cleaning in global.

I will updated more details soon. Your bookmark will be the biggest encourage for me.
