The laser marking machine is characterized in that high density laser beam is used to irradiate on the workpiece, and the surface of the workpiece is absorbed by laser energy. Thus, the surface of the material is deformed, melted, ablated, evaporated, etc. to form marks. At present, the laser marking machine has been widely used in various industries, playing the role of anti-counterfeit tracking, delicate and beautiful.

At present, laser marking machines can be divided into semiconductor laser marking machines, CO2 laser marking machines, optical fiber laser marking machines, etc. according to different laser sources. Generally speaking, semiconductor and optical fiber laser marking machines are suitable for marking metal, metal, metal and other materials. Plastic. CO2 laser is mainly aimed at non-metallic materials, such as acrylic acid, transparent plastics, ceramics and glass.

How to select the appropriate laser marking machine? This requires you to master these points!

Laser light source of marking machine - if the hardware of workpiece processing, plastic, label paper and other materials with longer wavelength are optical fiber laser marking machines; If it is a carbon dioxide laser marking machine for bamboo, cloth, ceramics, acrylic acid and other materials with shorter wavelengths; If it is a film, fruit, egg, carton, reinforced glass and other heat sensitive materials, use a medium wavelength ultraviolet laser marking machine.

Of course, it does not mean that a material is only suitable for one laser source. Multiple laser sources can be used for the same material, depending on the accuracy of your processing requirements.

Marking machine power - Laser power is sometimes the key to determining speed and effect. Generally, like UV engraving paper, film and plastic, it has a marking power as low as 1.2w. But glass carving requires 3W or even 5W ultraviolet light to move. Like hardware, you can use 20W fiber. However, if high efficiency and high speed are pursued, 30W or higher power is required.

The main hardware structure of the marking machine - the main hardware structure of the laser marking machine, including laser, laser scanning galvanometer, focusing system, laser power supply and calculation notification system. You only need to choose whether to import or domestic according to your processing needs, especially the requirements for high accuracy, and make clear with the manufacturer.

Calculation notification system - There are many kinds of software used by the laser marking machine, some are conventional, some are self-developed, or the conventional software will be re developed to decide which software to use. It is necessary to find out whether there will be secondary development needs.

The price of the marking machine - In fact, the price is more customer demand configuration and changes, so here are only some general reference prices. The price of ordinary optical fiber laser marking machine (20w-50w) is 20000-80000; The price range of CO2 laser marking machine (10w - 100w) is from 30000 to 180000; The price range of ultraviolet laser marking machine (1.2w-10w) is 60000 to 260000.

In addition, the requirements of laser equipment in terms of accuracy, engraving effect, speed, automation, customized fixture, etc., need to be proposed to the manufacturer in advance. I made confirmation during and out of the plan to test the samples, so as to avoid that the purchase did not meet the user's requirements for the use of the marking machine and affected the user experience. The service life, stability, portability and after-sales service of the marking machine are considered. The service life and stability depend on whether the heat dissipation effect is good, whether the brand is large enough and whether the portability depends on the appearance and model of the product.
