The laser marking machine is characterized in that a high-density laser beam is used for irradiating on a workpiece, and the surface of the workpiece is absorbed by laser energy. So that the surface of the material is deformed, melted, ablated, evaporated and the like to form an identification. At present the laser marking machine has been widely used in various industries, played a role in anti-counterfeiting tracing, delicate and beautiful.
Currently, laser marking machine can be divided into semiconductor laser marking machine, CO2 laser marking machine, fiber laser marking machine and so on according to the laser source.Generally, semiconductor and fiber laser marking machine is suitable for marking materials, such as metal and plastic. CO2 laser is mainly aimed at non-metallic materials, such as acrylic, transparent plastics, ceramics and glass.
So how to choose a suitable laser marking machine? That requires you to master these points!
Marking machine laser source- If the process workpiece hardware, plastic, label paper and other materials with a longer wavelength of optical fiber laser marking machine; If it is bamboo, cloth, ceramics, acrylic and other materials with a shorter wavelength of co2 laser marking machine; If it is film, fruit, eggs, cartons, reinforced glass and other thermal materials with moderate wavelength uv laser marking machine.
Of course, it is not that a material is suitable for only one laser source. The same material can use a variety of laser sources, it depends on the precision of your processing requirements.
Marking machine power- Laser power is sometimes the key to determine the speed and effect. Generally, like ultraviolet engraving paper, film, plastic, with a low power of 1.2w marking. But the carving of glass requires ultraviolet 3W, or even 5W power to move; Like hardware, you can use optical fiber for 20W. But if the pursuit of high efficiency and high speed, it takes 30W or higher power to achieve.
The main hardware structure of marking machine- The main hardware structure of laser marking machine, including laser, laser scanning galvanometer, focusing system, laser power supply and calculation notification system, you only need to choose according to your processing needs is imported or domestic, especially for high precision requirements, and the manufacturers clearly.
The calculation notification system- There are many kinds of software used in the laser marking machine, some are routine, some are developed by themselves, or the routine software will be re-developed, decide which software to use, you need to figure out whether there will be secondary development needs.
Price of marking machine- In fact, the price is more customer demand configuration and change, so here only to give some general reference price, general fiber laser marking machine (20w-50w) price 20,000-80,000;Carbon dioxide laser marking machine (10w-100w) price range from 30,000 to 180,000;Ultraviolet laser marking machine (1.2w-10w) price range from 60,000 to 260,000.
In addition, the laser equipment in the use of precision, carving effect, speed and with automation, custom fixture and other requirements, need to advance to the manufacturer. In the process of testing samples and out of the plan to confirm, so as not to buy does not Conform to the user's use requirements of the marking machine, affecting user experience.The consideration is the marking machine life, stability, portability, after-sales service.Like life and stability depend on whether the heat dissipation is good or not, whether the brand is big enough, and the portability depends on the appearance and model of the product.
