Therese Guo

In recent years, along with the increasing application of the 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:

  • Whether the laser marking machine is the most suitable machine for your products.
  • 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.
  • 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.
  • 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.
  • Compare prices based on machine details and after-sales service. Quality and service are the decisive factors for price. Just compare prices is meaningless.

  1. 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.
