45W RF-CO2 Galvo Laser Marking Machine

This Laser Marking Machine operates on an RF CO2 DAVI laser source from Dawei Laser Technology in Beijing, a reputable manufacturer of high-quality CO2 laser equipment. The company invests heavily in research and development in laser technologies and is known for its customer service and technical support. The laser source has a superior laser beam with a small divergence angle, integrated laser structure, and stable performance. The machine has a high-speed galvanometer scanning system. It’s easy to operate, highly reliable, and with a long lifespan of over 45,000 hours. The equipment is highly efficient and operates at a low processing cost without consumables. It covers a  large marking area and produces remarkably high accuracy and precision results.

CO2 laser engravers are excellent for organic materials like rubber, wood, paper, glass, and ceramic. They are also the go-to choice for cutting acrylic and other plastics. CO2 systems are the most common laser used for industrial engraving and cutting. Using CO2 gas in a sealed tube, acting as the laser medium, they operate at the 10,600nm wavelength. RF laser sources can operate at high repetition rates and have low power drift. In addition, they have higher beam quality.

The radio frequency RF CO2 lasers are superior to regular glass-tube CO2 lasers. There are several major advantages of RF CO2 lasers:

 RF-CO2 Lasers Advantages

• Long lifetime - RF CO2 laser source has a lifespan of more than 45,000 hours. It can generally be used for ~6 years, and it can be used repeatedly without replacement; while the glass tube CO2 laser’s lifespan is about 2500 hours, usually replaced every six months.
• Non-breakable Case Design - RF CO2 lasers are manufactured using imported glass tubes enclosed in a special sturdy metal case.
• Cooling Method - RF C02 lasers utilize air cooling, which can ensure long-term trouble-free and stable operation; CO2 glass tube lasers utilize water cooling, which requires an additional device to keep the water cold, and also makes the laser marking process less stable.
• Beam Quality - RF CO2 laser produces a fine spot of 0.07mm, which is more than 3 times smaller than glass tube CO2 laser with a spot of 0.25mm, which ensures high precision, a small thermal diffusion area, and the ability to engrave/cut very fine works with high accuracy.
• Stability - The RF tube is a fully sealed metal tube with a 30V low-voltage power supply. Consequently,  there are no disadvantages and dangers associated with using 10,000V high-voltage power and unstable domestic glass tubes.
• High-Speed - Quick operation thanks to galvo scanner technology.

Laser Source Technical Parameters

Galvanometer Scanner Technical Parameters

Sino-Galvo is a leading manufacturer of optical galvanometer scanners for laser equipment. The  RC1001 model is an ideal galvanometer for laser marking machines, with good running stability, high positioning accuracy, fast marking speed, and strong anti-interference ability. It has a standard 10 mm wide laser aperture and M85 thread lens housing. The galvanometer connects to the control board with a DB25 serial cable; it operates on a 15V power supply and is compatible with lasers emitting 355 nm, 1064 nm, or 10600 nm wavelengths. The high-performance rotary motors convert the instructions from the controller into precise movements of the X and Y mirrors to mark your artwork, including text, designs, logos, serial numbers, bar codes, etc., on metal, stone, plastic, and organic materials at high speeds. The size of the working field depends on the installed F-Theta field lens. The built-in red dot projectors make the positioning of the scanner at the correct focal length fast and convenient.
