CO2 laser coding machine(100w) Working principle

The carbon dioxide laser coding machine uses CO2 gas as the medium to complete product marking.

CO2 gas is filled in the laser tube of each machine, and electrode plates are configured to generate discharge.

The electrode plate is connected to an external power source, allowing high-frequency power to be applied as an excitation source. Due to the discharge between the electrodes, plasma is generated in the gas, and CO2 molecules will transform into excited states. As the quantity increases, they begin to be stimulated and radiated.

In addition, in order to oscillate light back and forth, a pair of mirror surfaces are set up to form a resonator. Light will travel back and forth between the total reflection mirror and the output mirror, and after amplification, it will be output as laser.

Laser performs "thermal processing" on the surface of the product, burning out edited identification content or printing variable data information through online communication.

Introduction to CO2 laser coding machine 100W

All models in the series use air-cooled laser sources, which require almost no maintenance and can significantly reduce downtime. In terms of stability, it has a huge advantage over traditional ink jet printers.

At the same time, the service life of the laser source is longer, with an average time between failures (MTBF) of about 40000 hours. The high marking accuracy of the standard 100 * 100mm marking area greatly improves the adaptability of the product.

In daily use, it can be used independently or paired online, making production line integration more convenient. With a standard IP54 protection level, it is suitable for continuous and stable operation in harsh environments with high dust and humidity, allowing users to have no worries.

Finally, let's take a look at the application of CO2 laser coding machines with different wavelengths.

The full range of CO2 laser machines has multiple wavelengths to choose from, providing more ideal solutions based on the actual material and application needs of customers' products. There are three common wavelength bands.

10.6 microns: Very suitable for most standard packaging consumer goods applications, such as paper, cardboard, various plastics and labels, as well as wooden and glass products, etc;

10.2 microns: most suitable for laminated paper boxes commonly used in many cosmetics and pharmaceutical applications;

9.3 microns: particularly suitable for labeling on PET plastic (usually beverage products);

The marking material, laser wavelength, and laser type all affect the marking effect. You can refer to and choose according to your product material situation and industry application. For more product information and parameter data, please feel free to consult.

Rich printing content, suitable for various materials

Printing types: text, numbers, barcodes, QR codes, photos, patterns, production dates, production batch numbers, etc. Printing materials: various metals, monocrystalline silicon wafers, IC grains, plastic materials, food packaging films, etc.
