  Plastic is a common thing in our life. Plastic laser marking machine generally refers to carbon dioxide laser marking machine. Generally, laser marking machine is widely used in metal and non-metal marking. Laser marking machine can be applied to numbers, texts, trademarks or machine-readable codes, such as data matrix codes with high information density and arranged in close space with different scales. What are the characteristics of laser marking machine in plastic marking?

  1. Precision marking: the laser is a diode pumped laser with high energy efficiency. As well as metal marking machine, it has good focusing ability, so it is very suitable for fine marking. The diode pumped solid-state laser has a high beam quality, which makes the laser beam in the marking process obtain a small focusing diameter. In this way, the precision marking track width as small as micrometer can be realized on the micro parts.

  2. Adaptation of absorption characteristics: the laser used for marking usually produces radiation within the infrared wavelength range. UV lasers are for plastics and semiconductor materials. In the special application of laser marking machine, the use of UV wavelength has opened up a new possibility of laser marking on plastics. The short wave length directly reacts with the plastic compound to produce photochemical reaction without heating, which will not damage the material. It plays an important role in the laser marking machine in the plastic industry!

  At present, in the application of plastic marking, the potential of laser is far from being realized. The increasing promotion of frequency doubled laser and frequency tripled laser, as well as the diversity of combination of materials and processes, are opening up more new fields for the application of laser in plastic industry. Laser marking machine in plastic marking, in addition to free of consumables, no pollution, but also has the characteristics of fast speed, good marking effect, strong anti-counterfeiting, widely welcomed by enterprises.
