Color Laser Engraving Machine with Rotary Attachment
Color laser engraving machine is a type of automatic CNC laser marking system that uses MOPA fiber laser generator to mark colors on stainless steel, titanium, and chromium. MOPA laser marking system uses a high-energy density laser heat source to act on the metal surface to generate colored oxide on the surface, or generate a colorless and transparent oxide film, which presents a colorful effect due to the light interference effect of the film. By controlling the laser energy and parameters, the oxide layers of different thicknesses can present different colors to achieve the purpose of color engraving.
The full name of MOPA is Main Oscillation Power Amplification, which is to couple the seed signal light and pump light with high beam quality into the double-clad fiber for amplification in a certain way, so as to realize the high power amplification of the seed light source. MOPA laser marking machine has certain advantages in the marking of special materials, such as laser blackening of digital product parts, mobile phone keys, transparent keys, mobile phone shells, key panels, electronic components, oxidation, plastic marking, oxidation treatment and coating surface marking such as electroplating and spraying, and color patterns on stainless steel materials can also be marked.
The advantage of MOPA laser is that its pulse width and frequency are independently adjustable. Adjusting one of them will not affect other laser parameters, which is not available in Q-switch lasers. The characteristics of MOPA structure bring unlimited possibilities for color marking. In the actual marking operation, the pulse width, frequency, power, speed, filling method, filling interval, delay parameters and other factors will affect the color effect. The influence of these parameters will make the characteristics of the color change not obvious, but they are interrelated and affect each other.
The principle of color laser marking machine is: using an advanced MOPA laser generator, the high temperature generated by laser focusing makes the surface material of the material evaporate to expose the deep material, or the chemical and physical changes of the surface material caused by light energy to display the marking information.
There are three color rendering methods on metal surface: one is to generate colored oxides; the other is to generate a very thin colorless and transparent oxide film on the surface of stainless steel under the action of chemistry, electrochemistry or laser. The oxide film produces interference effects. The color appears on the surface; the third is that there is a mixed state of colored oxide and oxide film at the same time.
Color rendering principle of laser marking: under the action of the laser heat source, the metal generates colored oxide on the surface, or a colorless and transparent oxide film is formed, which presents various colors due to the interference effect of the light film. This is a metallic color. The basic principle of marking.
The following table shows the colors of several main oxides after the metal surface is oxidized by laser.
| Oxide | Fe3O4 | Fe2O3 | FeO | Cr2O3 | CrO3 | MnO | MnO2 |
| Color | Black | Red Brown | Black | Green | Dark Red | Green | Dark Brown |
Under the action of the laser, the metal surface produces a laser thermal effect. Through the laser thermal effect, it is obtained that the laser energy density is proportional to the film thickness. As the laser energy increases, the color of the metal surface shows regular changes: yellow, red, blue, green until green gradually darkens. By controlling the laser energy density, the desired color can be produced on metal materials such as stainless steel, chromium, and titanium.
1. The laser engraver adopts a scanning system for high-speed magnetic induction motor control with laser routes to the advantages of high accuracy and speed.
2. Fiber laser model has a over 100,000 hours service life. Almost no maintenance during this period.
3. Permanent marking: Laser marking is a permanent marking. It won’t fade, run or become less discernable as time passes like traditional marking including ink jet, hand engraving, dot-peen marking.
4. Support coding, serial number, batch number, date number, two-dimensional bar codes and other codes marking.
5. Processed products arbitrary depth adjustable: Marking a clear, beautiful, permanent and difficult to wear.
6. High precision: 0.0025mm re-position accuracy. Minimum line width 0.01mm.
7. Non-contact process: Won’t cause mechanical extrusion or mechanical stress to materials. Laser beam won’t move the work piece.
8. Powerful software, which can support autocad, CordlDRAM mapping dxf, plt and bmp format.
9. Support almost all Windows-based software like Coreldraw, AutoCAD, Photoshop. No need to adjust Q-switch easier than YAG diode marking machine.
10. The rotary attachment is optional for cups, rings, pens, and more rotating marking projects.

What an amazing fiber laser machine, I have to say I am very impressed with the amount of detail this machine can achieve, its able to connect with my laptop application is very easy to use although its not very well explained it is easy to figure out what does what, I was able to get this up and running in no time at all.
High-quality hardware, shipped on time, very accurate and precise engraving quality, very versatile, very easy to set up, and so far very reliable. I am floored with the capability I got for the price. The company is very easy to get ahold of. I can communicate with them emails or phone. They do communicate in English very well.
This kit is easy to put together with the well-written instruction manual, I have already got the color laser engraver running today. Works well on stainless steel business card. Ill try more in the next days and update the review down the road.
STYLECNC worked very well with me to insure that I was happy with the transaction. The best color laser engraver supplier to work with Fast, Professional, and Great Communication! I will buy again from STYLECNC in the future!
I admit I did not expect a lot, however this machine turned out a pleasant surprise. It is quite well designed and thought out to the small details. Very neatly packed and nothing missing. Was relatively easy to assemble - requires just basic skills. All needed tools are supplied too. The color laser engraving machine is precise and quiet enough to be used in a living room. The seller is very responsive. Recommended.
Not as big as I expected, but more portable, easy to use, to do color engraving on large areas like a jacket lay it out and put the engraving on top, works fine.
