Guide to Buying a CO2 Laser Marking Machine for Beginners

CO2 laser marking machine has become a marking tool in many industries due to its unique advantages. This guide comprehensively introduces the working principles, characteristics, application fields, and key points of use and maintenance of CO₂ laser marking machines and other aspects of knowledge, to help you gain an in-depth understanding of this efficient and accurate marking equipment, so as to better utilize its value.

What is CO2 Laser Marking Machine?

A CO2 laser marking machine is a type of laser marking system that uses a carbon dioxide (CO2) laser to mark materials. CO2 lasers are known for their high power and efficiency in engraving, cutting, and marking a variety of materials, including wood, plastics, glass, ceramics, and certain metals.

Working Principle of CO2 Laser Marking Machine

CO2 laser marking machine is a commonly used laser marking equipment that uses CO2 laser as an energy source. Its working principle is based on the energy level transition of CO2 molecules.

CO2 laser marking machines contain a CO2 laser tube filled with mixed gas, usually consisting of carbon dioxide, nitrogen, and other inert gases. When energy is provided by an excitation source (such as a high-frequency current or discharge), the CO2 molecules are excited and placed in a high-energy state.

Mirrors are set at both ends of the CO2 laser tube, one of which is translucent to allow part of the laser to pass through. During the excitation process, high-energy CO2 molecules undergo spontaneous emission, producing a laser beam of a specific wavelength. This wavelength is typically 10.6 microns, which is within the infrared spectrum.

The laser beam is collimated, expanded, and focused through the optical system, ultimately forming a small and dense spot. This spot can be focused onto the work object to produce a high energy density light spot. When the laser beam interacts with the material, it creates a photothermal effect that causes the material in the area to vaporize, peel off, or chemically change, forming a visible mark.

Features of CO2 Marking Machine

Multi-material Applicability

CO2 laser marking machine is suitable for a variety of materials, including metal, plastic, glass, ceramics, paper, leather, etc. It can achieve high-quality marking results on these materials.

High Precision and Clarity

CO2 laser markers can achieve high-precision marking and can meticulously engrave various details such as text, patterns, and QR codes. It produces a smaller diameter laser beam that allows for very fine markings.

Non-contact Operation

CO2 laser marking machine adopts a non-contact marking method without direct contact with the workpiece surface. This reduces the risk of damage to the material and is suitable for marking sensitive and fragile materials.

Efficient Production and Speed

CO2 laser marking machines have high working speeds and can achieve fast and continuous marking operations.

Flexibility and Customizability

CO2 laser engraving machines can be adjusted and customized according to different needs. By adjusting settings such as laser power, focal length, and scanning parameters, applications with different materials and marking requirements can be met.

Environmental Protection and Energy Saving

CO2 laser marking machine uses CO2 gas as the laser medium, without the use of chemical fluorescent agents or dyes. It does not produce pollutants or waste liquid and is an environmentally friendly and energy-saving marking technology.

Application of Industrial CO2 Laser Marker

CO2 laser marking machines have a variety of industrial applications. The following are some common application examples:

Plastic Products

CO2 laser marking machines can mark and engrave plastic products, such as electronic product casings, plastic pipes, etc.

Wood Processing

CO2 laser marker can mark the surface of wood with letters, patterns, and serial numbers, and is used in furniture, wooden handicrafts, and other industries.

Food Packaging

CO2 laser marking machines are widely used in the food packaging industry and can mark batch codes, date codes, and bar codes on cartons, plastic bottles, glass bottles, and other containers.

Pharmaceutical Industry

CO2 laser marking machine can permanently mark pharmaceutical packaging, such as medicine bottles, medicine boxes, etc., to ensure product traceability and anti-counterfeiting.

Auto Parts

CO2 laser engraving machines are often used to mark and engrave auto parts, such as engine parts, tires, frames, etc., to track production information and provide anti-counterfeiting functions.

Metal Products

Although the direct marking effect of CO2 laser on metal is weak, additives and other methods can be used to react on the metal surface to achieve marking on metal products.

What Materials Are CO2 Laser Marking Machines Suitable for?

CO2 laser marking machine is suitable for many non-metallic materials, such as plastic, wood, glass, leather, paper, etc. For some metal materials, additives or coatings are required to achieve marking.

What Types of Markings Can the CO2 Laser Marking Machine Make?

CO2 laser marking machines can carry out various markings such as engraving, patterns, serial numbers, bar codes, and QR codes. It has high accuracy and flexibility, allowing customized marking according to needs.

How Much Does a CO2 Laser Marking Machine Cost?

CO2 laser marking machine price is a major factor in selecting the best one for your business. How much does a CO2 laser engraver cost? how to get a final price? According to different machine configurations, you will get the cost from $4,000.00 to $15,000.00 and even more.

What determines the price? For the best CO2 laser to suit your needs, the marking software, engraving material, laser power, and other production parts determine the price of the CO2 laser marker. If you have an idea to find the best and most economical solution for your marking needs overseas, the fee of customs clearance, tax, and shipping costs should be included in the final price.

What is the Marking Speed of CO2 Laser Marking Machine?

The marking speed of CO2 laser marking machine depends on the marking content and material type. Typically, it enables a fast and efficient marking process.

Does CO2 Laser Marking Machine Need Maintenance?

Yes, CO2 laser marking machines require regular maintenance to ensure their normal operation. Maintenance may include lens cleaning, gas line inspection, cooling system maintenance, etc. It is crucial to follow the maintenance guidelines provided by the manufacturer.

Is CO2 Laser Marking Machine Safe?

CO2 laser marking machines are relatively safe equipment when operated and used correctly. However, due to the characteristics of the laser beam, relevant safe operating procedures must be followed, such as wearing appropriate protective glasses to avoid direct exposure to the laser beam.
