Ultraviolet laser diode high-precision marking machine marking plastic
Aug 17 , 2021Plastic is a common item in daily life. Plastic laser marking machine generally refers to ultraviolet laser marking machine. Generally, laser marking machines have a wide range of markings 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 on different scales. Data matrix code. What are the characteristics of laser marking machine on plastic marking?
1. Precision marking: The laser is a diode-pumped laser with high energy efficiency. It also has good focusing ability like metal marking machine, so it is very suitable for fine marking. The diode-pumped solid-state laser has a high beam quality, which enables the laser beam in the marking process to obtain a small focus diameter. In this way, precision marking track widths as small as micrometers can be realized on tiny parts.

2. Adaptation of absorption characteristics: The laser used for marking usually produces radiation in the infrared wavelength range. Ultraviolet 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 it does not damage the material; it plays a pivotal role in the plastics industry in laser marking machines!
For now, in the application of plastic marking, the potential of lasers is far from being used. The increasing promotion of frequency doubled lasers and frequency tripled lasers, as well as the diversity of combinations of materials and processes, are contributing to the development of lasers in the plastics industry. Open up more new areas in the application of Chinese. In addition to free of consumables and pollution-free, the laser marking machine for plastic marking also has the characteristics of high speed, good marking effect and strong anti-counterfeiting, which is widely welcomed by enterprises.
