Characteristics of Laser Marking Machine for Plastic

in Blog,

Plastic is a common material in life, and the plastic laser marking machine generally refers to the co2 laser marking machine. Generally, laser marking machines can mark a wide range of metals and non-metals. Laser marking machines can be used for numbers, text, trademarks or machine readable codes such as Data Matrix codes with high information density arranged in tight spaces at different scales.

What are the characteristics of laser marking machine for plastic?

1. Precision marking: The laser is a diode-pumped laser with high energy efficiency. Like the metal laser 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 quality, which enables 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. 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 for plastic industry!

For now, in the application of plastic marking, the potential of lasers is far from being brought into play. The increasing promotion of frequency-doubling lasers and frequency-tripling lasers, as well as the diversity of combinations of materials and processes, are opening up more new areas for laser applications in the plastics industry. In addition to being free of consumables and pollution, the laser marking machine has the characteristics of fast speed, good marking effect and strong anti-counterfeiting, which is widely welcomed by enterprises.
