The laser marking machine uses a high-density laser beam to irradiate the workpiece, which is absorbed by the laser energy. Thus, the surface of the material is deformed, melted, ablated and evaporated 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 materials. CO2 laser is mainly aimed at non-metallic materials, such as acrylic acid, transparent plastics, ceramics and glass.
Types and differences of laser marking machines
How to select the appropriate laser marking machine? Here's how:
Laser light source of the marking machine - if the workpiece being processed is a material with a longer wavelength, use the optical fiber laser marking machine; Carbon dioxide laser marking machine shall be used for materials with short wavelength; If it is a thermal material, 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 also be used for the same material, depending on the accuracy of your processing requirements.
Marking machine power - laser power is the key to affect speed and effect. Usually, like engraving paper, film and plastic, only 1w and 2w marking power are required. However, glass carving requires 3W or even 5W ultraviolet light for marking. If it is a very hard material, you can use a 20W optical fiber laser marking machine. However, if high efficiency and high speed are pursued, 30W or higher power is required.
The main hardware structure of the laser 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.
Calculation notification system - The laser marking machine uses many kinds of software, some are conventional, some are self-developed. If you want to decide which software to use, you need to know whether there will be secondary development needs.
The price of laser marking machine - in fact, the price changes with the change of customer demand configuration, so here only some general reference prices are given. 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, if the laser equipment has requirements on precision, engraving effect, speed, automation, customized fixture, etc., it needs to be proposed to the manufacturer in advance. In order to avoid affecting the user experience by purchasing a laser marking machine that does not meet the user's requirements. What we need to consider is the service life, stability, portability, after-sales service, etc. of the marking machine.
