Application Of Fiber Laser Marking Machine In Plastic Marking

Fiber laser marking machines have been widely used in the field of plastic processing in recent years. Its efficient and precise marking capabilities make it the preferred equipment for many industries. However, many people still have doubts about the safety and effectiveness of fiber laser marking machines on plastics. This article will explore in detail the application of fiber laser marking machines in plastic marking and how to avoid possible damage.
1. Working principle of fiber Laser marking machine
Fiber laser marking machines emit a high-energy-density laser beam and focus it on the surface of the plastic. The energy of the laser causes the surface of the plastic to evaporate instantly, forming a clear mark. Compared with traditional marking methods, laser marking does not require the use of ink or other consumables, reducing material waste while improving production efficiency.
2. Will it damage the plastic?
Whether the plastic will be damaged when using a fiber laser marking machine depends mainly on multiple factors, including laser power, marking speed, and the type of plastic. If the laser power is too high or the parameters are set improperly, it may indeed cause the plastic to overheat and cause damage. Therefore, reasonable parameter settings are essential.
In general, the power of fiber laser marking machines is not high and is suitable for most plastic materials. Plastics are generally not harmed as long as the operator can properly adjust the power and speed. The laser marking machine is designed to effectively evaporate a thin layer on the surface of the plastic without affecting the overall structure of the material.
3. Suitable plastic materials
Although fiber laser marking machines are suitable for a variety of plastics, some less resistant plastics should still be used with caution. It is recommended to conduct small-scale trials before formal production to determine the best marking parameters. Through multiple experiments, operators can find the laser power, speed and frequency settings that are most suitable for a specific plastic.
If conditions permit, some less resistant plastics may be better suited to using a CO2 laser marking machine in some cases. The laser wavelength and energy characteristics of this machine are more suitable for processing certain types of plastics.
4. Permanence of marking
An important advantage of fiber laser marking is the permanence of its marking. Because laser marking is semi-permanent, the mark will not be easily wiped off unless the surface of the mark is damaged with force. This makes laser marking very popular in applications such as product tracking, brand identification and security and anti-counterfeiting.
After laser marking, the color of the mark is usually similar to the original material. For metal materials, such as stainless steel and iron, it may be necessary to increase the laser power to present different color effects. These colors may not be obvious when the parameters are not adjusted enough.
5. Summary
In general, fiber laser marking machines perform well in plastic marking, and as long as the parameters are adjusted reasonably, they usually do not cause damage to the plastic. This technology is not only efficient, but also can achieve high-quality marking, and is suitable for a variety of industries such as electronics, automobiles, medical, etc.

In order to ensure the best results, it is recommended that operators conduct sufficient experiments and parameter optimization, and seek help from professionals when necessary. By continuously accumulating experience, enterprises can better utilize fiber laser marking machines and improve production efficiency and product quality. This flexibility and efficiency make fiber laser marking machines an indispensable tool in modern manufacturing.
