CO₂ Laser Marking Machine

A CO₂ laser coding machine uses carbon dioxide gas to create a powerful laser beam. The gas is stored in a sealed tube, and when the machine is turned on, electricity passes through the gas, making it release energy and form a plasma. This energy excites the CO₂ molecules, pushing them to a higher energy level. As the molecules become excited, they begin to give off light. The machine uses two mirrors to focus this light. One mirror reflects all the light, and the other lets some light pass through. The light bounces between the mirrors multiple times, making it more focused each time.

PRODUCT OVERVIEW

A CO₂ laser coding machine is a type of laser that works using carbon dioxide gas.The gas stays inside a sealed glass or metal tube, where special plates send in electric power. When the machine is turned on, the electricity moves through the gas, making it active and creating plasma. This process gives energy to the CO₂ gas molecules, lifting them to a higher energy level.

When many molecules get excited, they start to give off light. To turn this light into an intense and focused laser beam, the machine uses two mirrors at each end of the tube. One mirror reflects all the light, and the other lets some light go through. The light keeps bouncing between the mirrors, getting stronger each time.

Finally, the stronger light comes out through the semi-reflective mirror as a sharp, fast laser beam. This beam can mark, engrave, or print on many types of materials with high speed and accuracy. CO₂ lasers are trusted for being reliable, easy to care for, and able to give precise, lasting results in many factory and business uses.

An air-cooled laser source is simple to use and does not need much care. This keeps the machine working well with almost no stopping time.

The laser source works for a long time and can run for about 40,000 hours before it may have any issues.

Its usual marking area is 100x100 mm, and it is very accurate and has clear edges, helping you work faster and complete more tasks.

The standard IP54 protection keeps the machine safe from dust and water, allowing it to work smoothly and reliably even in harsh conditions.

You can pick from different working distances, and the printhead can be set in any direction from 0 to 360 degrees. This makes it easier and more flexible to fit into various production lines.

Product Advantages

Different wavelength choices

Our CO₂ laser range offers different wavelength choices, making it simple to pick the best one for your needs.

10.6 microns is perfect for marking common packaging materials such as paper, cardboard, plastic, labels, wood, and glass.

10.2 microns: ideal for marking laminated cartons, commonly used in cosmetic and pharmaceutical packaging.

9.3 microns: great for marking PET plastic, often used in drink bottles and similar items.

Laser marking result

The quality of the mark depends on the material, the laser’s wavelength, and the type of laser technology used.

The laser reacts with the material, causing a color change due to a chemical change.

Making a design on the product’s surface, like raising patterns on PET by foaming or carving into glass.

Removing the top layer of coating to show the different base color underneath.

Heating or burning wood or cardboard in a controlled way to darken or mark the surface.

Heating different plastics to create raised or pressed surface textures.

Product Applications

CO₂ lasers are gas-based systems that use carbon dioxide as the active medium, making them ideal for delivering clear, consistent, and high-quality markings on a wide range of materials such as cardboard, glass, coated metals, paper labels, PET, acrylic, and other plastics. Renowned for their adaptability and accuracy., these lasers produce permanent, high-contrast marks without any physical contact, preserving the integrity of even delicate materials.

They operate at high speeds, which boosts productivity in demanding industrial environments, and their low maintenance requirements ensure long-term reliability. CO₂ lasers are also an environmentally friendly solution, using no inks or solvents and generating minimal waste. With customizable wavelengths and flexible installation options, they can be easily adapted to suit specific materials and production line configurations, making them a valuable tool for manufacturers seeking efficient, cost-effective, and eco-conscious marking solutions.
