MOPA laser marking machine-ZDJG-MPDB-01

MOPA laser marking machine

MOPA laser marking machine is also known as stainless steel color laser marking machine or aluminum oxide blackening laser marking machine, because it can easily blacken aluminum oxide and aluminum alloy. When marking stainless steel materials, you can change the color change of the material surface layer by adjusting the laser beam, so as to obtain different decorative effects. The pulse frequency and pulse width of MOPA laser marking machine are independent and controllable. Through the adjustment and matching of two laser parameters, a constant peak power output can be achieved and can be applied to a wider range of marking substrates. Besides, the first pulse is available, the pulse width adjustment range is wider, and the response speed is faster, which is not available in Q-switched lasers. This characteristic brings infinite possibilities for stainless steel color marking and aluminum oxide blackening. In the actual marking operation, pulse width, frequency, power, speed, filling mode, filling spacing, delay parameters and other factors will affect the color effect. MOPA laser marking machine has good laser characteristics and good pulse shape control ability, providing an ideal laser source for precision machining and other applications.

MOPA laser marking machine is mainly used in 304 stainless steel color marking, aluminum oxide blackening, black plastic whitening, white plastic blackening, anode stripping, coating stripping, semiconductor and electronic industries, as well as other sensitive material marking and PVC plastic pipe industries, such as mobile phone back cover, IPAD, aluminum blackening, mobile phone keys, plastic transparent keys, electronic components, integrated circuits (IC), electrical appliances, communication products, sanitary ware, tool accessories, knives Glasses, watches, jewelry, auto parts, bags, cooking utensils, stainless steel products and other quick marks.

Product features

The pulse frequency and pulse width are independently controllable: MOPA fiber laser has the advantages of usable first pulse, wider pulse width adjustment range, faster response speed, etc.

Aluminum oxide blackening and stainless steel color marking: mainly used in stainless steel color marking, aluminum oxide blackening, anode stripping, coating stripping, semiconductor and electronic industry, plastic and other sensitive materials marking and PVC plastic pipe industry.

Fast marking speed and high efficiency: the processing amount is significantly improved in the same time, speeding up the return on investment of users, and the engraving speed can reach ≤ 12000 mm/s. Suitable for harsh environment: integrated design, compact structure and small volume The surface area/volume ratio of optical fiber is high, and the heat dissipation effect is good. It does not need a huge water cooling system, but simply needs air cooling. It can work in a poor environment, such as under the conditions of high impact, high vibration, high temperature, and dust.

Application industry

Anodized aluminum blackening application: laser is used to mark black trademarks, models, characters, etc. on the surface of anodized aluminum materials. This application has gradually been widely used by Apple, Huawei, ZTE, Lenovo, Meizu and other electronic manufacturers in the past two years to mark black marks on the shells of electronic products, such as trademarks, models, etc. For such applications, only MOPA lasers can process them at present. Because MOPA laser has a wide pulse width and pulse frequency adjustment range, using narrow pulse width and high frequency parameters can mark the black effect on the material surface, and different gray effects can also be marked through different parameter combinations.

Aluminum oxide sheet surface stripping application: today's electronic products are becoming thinner and thinner, and many mobile phones, tablets, and computers use thin and light aluminum oxide as the product shell. When using a Q-switched laser to mark the conducting potential on a thin aluminum plate, it is easy to cause material deformation and produce“ on the back; Convex Hull”, It directly affects the aesthetic appearance. The smaller pulse width parameter of MOPA laser can make the material not easy to deform and the shading more delicate and bright white. This is because the MOPA laser uses a small pulse width parameter to make the laser stay in the material shorter, and has enough energy to remove the anode layer. Therefore, the MOPA laser is a better choice for the processing of stripping the anode from the thin aluminum plate surface.

Electronics, semiconductors, ITO precision processing applications: In the precision processing of electronics, semiconductors and ITO, fine scribing applications are often needed. Because of its structure, Q-switched laser cannot adjust pulse width parameters, so it is difficult to draw fine lines. The MOPA laser can adjust the pulse width and frequency parameters flexibly, which can not only make the lines fine, but also make the edges smooth and not rough.

In addition to the above several application cases, there are many different application differences between MOPA lasers and Q-switched lasers. Here are some typical application cases, as shown in the following table:
