In recent years, along with the increasing application of the Laser marking machine( https://www.stylecnc.com/fiber-laser-marking-machine/ ) in the processing industry, more and more people want to purchase a laser marking machine to complete their work. So how do we choose a suitable laser marking machine? First, we must pay attention to the following questions:
1. Whether the laser marking machine is the most suitable machine for your products.
2. Production requirements: Tell the suppliers about your production requirements, such as the number of products to be completed each day, the feature of the products. It will convenience for suppliers to recommend the suitable machine parts to you, such as rotary devices, conveyors, etc.
3. Understand the main configuration of the machine, laser source, control card, Field lens, and other special configurations. Then you can compare the main configuration of the machine when you purchase.
4. Ask after-sales service of the machine. During the operation of the machine, maybe you will have various problems. The good after-sales service will help you solve the problems in a short time. International trade always has jet lag problems. So when you buy the machine consider whether the seller can solve the after-sale problem in time.
5. Compare prices based on machine details and after-sales service. Quality and service are the decisive factors for price. Just compare prices is meaningless.
一.Types of laser marking machine：
There are 7 kinds of laser machines, respectively Lamp-pumped YAG laser marking machine, Semiconductor pumped laser marking machine, Fiber laser marking machine, CO2 laser marking machine, Mopa laser marking machine, UV laser marking machine, Green laser marking machine. Understand the types, working principles and applications of commonly used laser marking machines. Will help you choose the suitable laser marking machine. Now share the information of most common laser marking machines with you:
1.Fiber laser marking machine.
For marking on the metal, fiber laser marking is the best choice for you. Fiber laser marking machine adopts original Raycus Q-Switched Pulse Fiber Laser source. This series pulse laser has high peak power, high single-pulse energy, and optional spot diameter and can be widely applied in the fields, such as marking, precision processing, graphic engraving of non-metal, gold, silver, copper and aluminum with altitude stress resistance, stainless materials without altitude stress resistance. Its marking process features lower cost and more stable performance compared with traditional laser. All components of the 10-100W Q-switched pulse fiber laser are developed by Raycus independently, with high product reliability. And its good compatibility has well recognized by the market and its quality has reached the international advanced level. Up to 100,000 hours of service life. Fiber lasers also have high energy efficiency and low maintenance requirements, so they have the lowest cost of ownership.
Applied to engraving all kinds of metals, like gold, silver, copper, alloy, aluminum, steel, stainless steel, etc. And part of non-metal, such as engineering plastic and hard plastic, etc.
Application industry： Jewelry engraving, Medical devices, Phone case engraving, Hardware industry, stainless steel tableware, electron components marking, etc. Jewelry engraving, Medical devices, Phone case engraving, Hardware industry, stainless steel tableware, electron components marking, etc.
2.CO2 laser marking machine:
CO2 laser marking machine can mark permanent marks on the surface of a variety of nonmetal. CO2 laser marking machine is carbon dioxide laser marking machine, which uses CO2 gas as working medium. The CO2 laser uses CO2 gas as a medium and charges CO2 and other auxiliary gas into the discharge tube to apply high voltage on the electrode. After the laser is produced, the light transmission to the laser head through the refraction of several mirrors, and then by the laser head mounted focusing mirror to converge the light into one point, it will reach a very high temperature, the material will instantly be sublimated into gas by high temperature. Co2 Laser marking machine is a gas molecule laser, work material is CO2 gas, auxiliary gas is nitrogen helium, xenon, and hydrogen, the laser energy conversion efficiency up to 25%. Has the good stability.
3.MOPA color laser marking machine
“MOPA” is actually an acronym for Master Oscillator Power Amplifier. This type of technology was a breakthrough in DUV light source design.
The laser can mark different colors by adjusting the laser beam when marking metal materials such as stainless steel.
The advantage of MOPA color laser marking machine is the pulse width and frequency can be adjusted independently. When you adjust one of them, it will not affect other laser parameters. This is the difference from Q-switched lasers. This feature allows the MOPA color laser marking machine to mark many colors. In the actual marking operation, pulse width, frequency, power, speed, filling method, filling spacing, delay parameters and other factors will affect the color effect. Therefore, when you purchase the MOPA color laser marking machine, the exporters have professional operation knowledge is very important.

4.UV laser marking machine
UV laser marking machine includes violet and green laser marking machines.
The green light laser marking machine has a visible green wavelength of 532nm. It can achieve a clear marking on plastic materials and soft marking on silicon materials. It can also achieve high quality marking on reflective materials such as gold and silver.
