Can nanosecond UV laser process plastic PET film?

Plastic is a common item in life, and the plastic laser marking machine generally refers to the carbon dioxide laser marking machine. Generally, laser marking machines are widely used for marking on metals and non-metals. Laser marking machines can be applied to numbers, texts, trademarks or machine readable codes, such as those with high information density and arranged in tight spaces at different scales. Data Matrix Code. What are the characteristics of laser marking machine on plastic marking?

Can laser marking machine process plastic material PET film to mark?

1. Precision marking: The laser is a diode-pumped laser with high energy efficiency. Like the metal marking machine, it also has good focusing ability, so it is very suitable for fine marking. The diode-pumped solid-state laser has a high beam laser marking machine quality, enabling the laser beam to obtain a small focusing diameter during the marking process. In this way, precision marking track widths down to microns can be achieved on tiny components.

2. Adaptation of absorption characteristics: Lasers used for marking usually generate radiation in the infrared wavelength range. Green and UV lasers target plastic and semiconductor materials. In the special marking application of laser coders, the use of UV wavelengths opens up new possibilities for laser marking on plastics. The short wavelength directly produces a photochemical reaction with the plastic compound without heating, so that the material is not damaged; it plays a pivotal role in the laser marking machine in the plastic industry!

Can laser marking machine process plastic material PET film to mark?

Ultraviolet laser marking machine Laser marking machine is a product that can mark PET materials, and it is often used to mark production date, code, pattern, two-dimensional code and other information. Items made of PET material have the advantages of high strength, good transparency, non-toxicity, anti-penetration, light weight and high production efficiency, so they have been widely used and are used as computer floppy disks, metal coatings and photosensitive films. , can also be made into edible oil bottles, condiment bottles, cosmetic bottles and other packaging materials.

The working principle of laser marking machine marking PET is to focus the laser on the surface of the marked object with a high energy beam, and in a very short time, the end-pumped laser marking machine material on the surface of the PET material is vaporized and passed through. Control the effective displacement of the laser beam to accurately engrave clear and beautiful characters and LOGO on the PET material. The laser marking machine has a fast marking speed. The laser beam under the control of the industrial computer can move at a high speed (the speed can reach 5-7 m/s), and the marking process can be completed within a few seconds. And no consumables, no pollution and pollution, is a green marking equipment.

Can laser marking machine process plastic material PET film to mark?

The laser marking machine has high photoelectric conversion efficiency, adopts air-cooled cooling, the whole machine is small in size, and can be flexibly marked on PET materials, and the output beam quality is good and the performance is stable; the advanced laser is used to output the laser, and then the high-speed scanning vibration The mirror system realizes the marking function;
