Water-Cooled Flying CO2 Laser Coder for PET

This water-cooled flying CO2 laser marking machine is designed for on-line code printing on non-metallic products in production lines, with standard configurations of 30W and 50W laser power. It is widely used for marking expiration dates, batch numbers and logos on PET bottles, pharmaceutical tablets and packaging components, serving production facilities in beverage, pharmaceutical and food packaging sectors. The non-contact marking process eliminates the need for ink and other consumables, and supports continuous operation with conveyor belts to match high-volume production schedules.

Core Features of Water-Cooled CO2 Laser Code Printer

On-the-Fly Marking for Continuous Production Lines

This machine supports marking on moving products along conveyor belts without stopping the production line, which helps maintain continuous workflow and increase production throughput. It can be integrated into existing production line setups, with adjustable settings to adapt to different product sizes and line speeds. The scanning head carries an IP56 dust and waterproof rating, with anti-interference capability for industrial workshop environments.

Water Cooling System for Stable Long-Run Operation

The machine adopts a water cooling design to dissipate heat generated during laser operation. This cooling method helps maintain stable laser beam quality during continuous operation, reduces component wear caused by high temperature, and supports longer daily running hours. Regular maintenance of the cooling system can extend the overall service life of the equipment.

Control System and Connectivity

The machine is equipped with a multi-language operating system supporting more than 10 languages for operation by teams from different regions. It supports RS-232 and TCP/IP communication protocols for connection with production line control systems. Core components including the laser source, control boards and power supplies are integrated into a compact enclosure, with real-time voltage and frequency monitoring for operational status tracking.

Power Selection Guide for Industrial Marking Applications

The 30W configuration is suitable for small-format, fine marking tasks on thin materials such as PET films and tablet surfaces, where shallow and clear marks are required. The 50W configuration delivers higher energy output, supporting faster marking speeds and deeper mark formation on thicker or more heat-resistant non-metallic materials. When selecting power, buyers may consider three main factors: the type of base material, the required production line speed, and the desired mark depth, to match equipment performance with actual production demands.

Optional Accessories for Production Line Integration

The following accessories are available for custom configuration based on specific production needs:

Electric lift

100W / 200W smoke purifier and fume extractor

Foot switch for signal control

Conveyor belt assembly

Electric lift	Fume extractor	Foot switch	Conveyor

FAQ

What materials are compatible with this CO2 laser marking machine?

This machine is designed for non-metallic materials. It performs well on most plastics, rubber, ceramics, and plastic films, including PET, PVC, PP, ABS and natural rubber. It shows poor marking effect on most bare metal materials, and is not recommended for stainless steel, aluminum, copper and other uncoated metal substrates.

Can this machine integrate with existing conveyor production lines?

Yes. This flying marking model is designed for on-line production integration. It supports connection with existing conveyor systems via corresponding communication protocols, and can be adjusted to match different line speeds.

What is the expected service life of the laser source?

The sealed RF CO2 laser source has an expected service life of over 50,000 hours under proper operation and regular maintenance.

What are the electrical requirements for installation?

The machine works with L/N/PE power supply of 100 – 240 VAC, 50/60 Hz, adapting to common industrial power standards in most regions.
