A CO2 marking machine, also known as a CO2 laser marking machine, is a device that uses a laser beam to mark the surface of a variety of different substances with permanent markings. The effect of marking is the evaporation of the surface material to reveal the deep substance, so as to engrave exquisite patterns, trademarks, dates, logos or words. Here is a detailed introduction about the CO2 marking machine:

Working principle: It uses CO2 gas as the working medium, charges CO2 and other auxiliary gases into the discharge tube, adds high voltage on the electrode, and generates a glow discharge in the discharge tube, so that the gas releases a laser with a wavelength of 10.64μm. After the laser energy is amplified, it is scanned by galvanometer and focused by F-Theta mirror, and under the control of computer and laser marking control card, images, words, numbers and lines can be marked on the workpiece according to user requirements.
Peculiarity:
Strong processing versatility: Due to the long wavelength, carbon dioxide laser can be effectively absorbed and processed by many non-metallic materials, such as plastics, rubber, wood, leather, glass, ceramics and other common materials, suitable for different industries such as electronics, toys, advertising, handicrafts, etc.
High efficiency and precision: The high energy density of the laser beam allows the processing of materials in a very short time, increasing production efficiency. At the same time, due to the linearity and adjustability of the laser beam, it can achieve precise processing of the material surface, such as marking, engraving and cutting, to ensure the accuracy and consistency of processing.
Non-contact processing: In the process of laser processing, the laser beam acts directly on the surface of the material, without contacting the material, which can avoid damage and deformation caused by contact, especially suitable for materials with strict surface requirements, such as plastics, rubber, etc.
Stable laser performance: The use of CO2 lasers as the light source can maintain relatively stable output power and wavelength during long-term operation, ensuring continuous high-quality processing results, which is critical for consistency and stability requirements in large-scale production.
No consumables: Unlike other marking equipment, the CO2 laser marking machine marks directly on the surface of the material through the laser beam, eliminating the need for inkjet, coding and other consumables, reducing production costs and improving production efficiency.
Low processing cost: Its high efficiency and low consumables not only reduce production costs, but also reduce the impact on the environment, so that enterprises can better control production costs and improve competitiveness while pursuing high-quality and environmentally friendly production.
