CO₂ Laser Coding & Marking System

Product Overview

The G Series CO₂ Flying Laser Marking Machine is a high-performance, continuous-marking system engineered specifically for high-speed production lines. Designed to maximize productivity, this industrial laser coder features a QC industrial-grade metal RF CO₂ laser tube that delivers stable, uniform power output with excellent optical mode quality and fast processing efficiency.

Unlike traditional ink-based coders, the G Series provides permanent, tamper-proof, and consumables-free marking – no inks, no solvents, no replacement parts. Whether you're coding packaging materials, plastic bottles, glass containers, or cartons, this flying laser marker integrates seamlessly into your production line, delivering crisp, high-contrast codes at speeds that keep pace with your fastest throughput.

With 40W and 60W power options, a 110×110mm marking field, and dual red-light focusing for rapid setup, the G Series is the ideal solution for manufacturers seeking reliable, high-quality, low-maintenance coding.

Key Features Advantages

• High-Speed Continuous Marking – Built for Productivity

  The G Series is purpose-built for flying (on-the-fly) marking on continuous production lines. It operates at speeds that match your conveyor system, ensuring seamless integration without slowing down your throughput. Whether you're coding thousands of items per hour or marking continuous web materials, this machine delivers consistent, high-quality results.

• Industrial-Grade Metal RF CO₂ Laser Tube

  At the heart of the G Series is a QC industrial-grade metal radio-frequency CO₂ laser tube – a premium component that outperforms conventional glass tubes:

• No Shadows, No Virtual Disconnection – Perfect Marks on Special Materials

  Advanced laser source technology ensures clean, complete marks even on challenging special materials. Unlike inferior systems that produce shadowing or broken  lines on certain substrates, the G Series delivers crisp, unbroken characters, barcodes, and graphics every time – regardless of material composition or surface texture.

• High-Precision Dual-Axis Galvanometer Scanning System

  Equipped with a high-precision 2-axis galvanometer scanning system, the G Series achieves rapid, accurate beam positioning across the entire marking field. This ensures sharp, distortion-free codes at high speeds, with minimal line distortion at the edges of the marking area.

• Dual Red-Light Focusing – Fast Accurate Setup

  The 130mm focusing lens with dual red-light positioning allows operators to set the optimal focal distance in seconds. This intuitive visual guidance system reduces setup time, minimizes operator error, and ensures consistent mark quality from batch to batch.

• Generous Marking Field – 110×110mm

  With a marking range of 110mm × 110mm and a minimum line width of just 0.03mm, the G Series accommodates large product surfaces while delivering razor-sharp detail for small characters and barcodes.

• Dot Matrix Vector – All-in-One Versatility

  The G Series supports both dot matrix and vector marking in a single integrated system. This flexibility allows you to choose the optimal marking style for your application – whether you need high-speed dot matrix coding for dates and batch numbers, or high-resolution vector engraving for logos and complex graphics.

• Robust Reliable – Built for 24/7 Operation

  Engineered for demanding industrial environments, the G Series delivers consistent performance shift after shift. With minimal maintenance requirements and a long service life, it offers an exceptional return on investment compared to consumable-based coding systems.
