Mopa laser marking machine

Two days ago, I had a very pleasant comunication of mopa fiber laser marking machine and 6040 co2 engraving machine with a customer from the United States.
First of all, I am honored that the client chose DOWIN because of my service and professionalism. This article will discuss the after-sales service and guarantee of the fiber laser marking machine according to the customer’s problem. Thanks again for the customer’s problem and choosing Dowin!

Color marking on stainless steels as a process is known for sometime but still it has not been used widely in the industry. Some industrial applications have been seen. Dowin laser supply MOPA fiber laser marking machines allow independent tuning different laser parameters and the marking process can be optimized for producing colors with better quality and visual appearance. How to mark different color on stainless steel? Let us figure out the parameter setting.

1. It can be a variety of metal, non-metallic materials for processing.Especially for high hardness, high melting point, brittle material marking more obvious advantages.
2. belongs to the non-contact processing, does not damage the product, no tool wear, marking good quality.
3. The laser beam is good, the processing material consumption is small, and the processing heat influence area is small.
4. high processing efficiency, the use of computer control, easy to achieve automation.

Advantages
1.High electro-optic conversion efficiency, simple operation, Compact in structure, support harsh working environment, no consumables.
2.Low power consumption, stability laser output. the marking is permanent and corrosion resistant
3. High quality beam, small machine dimension,.This highly integrated laser source increases the machine’s anti-reflection ability with optical isolator, be able to mark on most high reflective materials such as aluminum, copper, gold and silver without the shadow and virtual open phenomenon.
4. Smaller output laser beam, finer marking line. suitable for high precision marking.
5.Modular design, separate laser generator and lifter, more flexible, can mark on bigger area and complicated surface. Air-cooled inside, small occupation, easy to install.

Mopa Laser Marking Machine in Alumina Sheet Surface Stripping Application
Nowadays, electronic products are getting thinner and thinner. Many mobile phones, tablets and computers use thin and light alumina as the outer shell of the products. When using a Q-switched laser to mark conductive potential on a thin aluminum plate, it is easy to cause deformation of the material and produce a “convex hull” on the back, which directly affects the aesthetics of the appearance. The parameters of the MOPA laser with a smaller pulse width can make the material not easily deformed, and the shading will be more delicate and brighter. This is because the MOPA laser uses a small pulse width parameter to make the laser stay on the material shorter, and the energy is high enough to remove the anode layer, so for the process of stripping the anode on the surface of the thin aluminum oxide plate, MOPA Lasers are a better choice.

Advantages of mopa laser marking machine
1. Flexible control, independent adjustable pulse width and frequency
2. Pulse shape controllable
3. Large adjustable range of parameters
4. Strong system upgrade ability
Use laser to mark black trademark, model, text, etc. on the surface of anodized aluminum material. In the past two years, this application has gradually been widely used by electronics manufacturers such as Apple, Huawei, ZTE, Lenovo, etc. for the shell of electronic products , used to mark the trademark, model, etc. of the black mark. For such applications, currently only MOPA lasers can process them. Since the MOPA laser has a wide range of pulse width and pulse frequency adjustment, the parameters of narrow pulse width and high frequency can be used to mark the black effect on the surface of the material, and different gray scale effects can also be marked by different parameter combinations.

Why Mopa can mark color on metal, whats the difference with normal fiber marker ?Generally, the pulse width of laser marking machine is fixed, the range is about 80-120ns, and the frequency is 20KHz-80KHz
MOPA laser marking machine (take IPG’s 20-watt as an example) has an adjustable pulse width of 2-200ns and a frequency of 1.6KHz-1000KHz. The MOPA laser marking machine has many pulse widths and a wide frequency range, so there are many combinations of various parameters, which can There are many kinds of effects, and there are many suitable materials and products. The function of stainless steel color marking and aluminum black marking is also one of the main functions of mopa laser marking machine.
