1.see marking material
Laser marking machine can be divided into: fiber laser marking machine, CO2 laser marking machine, UV laser marking machine according to different lasers.Different workpiece materials have different choices of laser marking machines and different wavelengths and powers are suitable for different materials. The wavelength of the fiber laser marking machine is 1064nm, which is suitable for metal marking.The power of the fiber laser marking machine is as follows:20w,30w,50w,100w,etc.
The laser wavelength of CO2 laser marking machine is 10.6μm, which is suitable for most non-metallic materials, such as leather, wood, plastic, cloth, acrylic, wood and bamboo, rubber, ceramics, etc. The power of CO2 laser marking machine are: 20W, 30W, 60W, 75w,100W, etc.
The laser wavelength of the UV laser marking machine is 355nm, which is mainly used for ultra-fine marking and engraving, and is especially suitable for marking food, pharmaceutical packaging materials, and glass materials. The power of UV laser marking machine are: 3W, 5W, 10W, 15W, etc.
2.Look at the size of the workpiece
After knowing the marking material, select the corresponding marking machine type, and then select the appropriate machine format according to the size of the product to be processed. For the choice of the size of the laser marking machine, it is not that the bigger the machine, the better. On the one hand, large-format equipment is of course more expensive. On the other hand, some machines and equipment with poor quality have unstable average laser output at each point on the large-format, resulting in different depths of marking products on the same table, so choose the most The right format is the right one.
3.see supplier qualifications
When many people choose a laser marking machine, they often focus on the contract and price, thus ignoring some qualification problems of suppliers, which is easy to leave unnecessary troubles for future work. When choosing a laser equipment supplier, it is best to inspect the other party in many aspects, such as whether the company has relevant licenses, whether the laser equipment has a qualification certificate, etc.
The competition in the laser industry is becoming increasingly fierce. When choosing, customers should not only pay attention to the quality of products and enterprise qualifications, but also learn more about the services provided by laser marking machine companies. You can refer to the reputation of market users, the quality of after-sales service of manufacturers, etc
