Product Introduction

The Fully Automatic Laser water marking machine is an innovative marking system designed for non-destructive, high-precision water-mark engraving on hard and brittle materials such as glass, sapphire, ceramics, and quartz.

It uses advanced laser interference and micro-ablation technology to create clear, smooth, and permanent watermarks inside or on the surface of materials — without causing cracks, micro-damage, or structural deformation.

Unlike traditional mechanical engraving or chemical etching methods, Inte Laser’s water marking system delivers contact-free processing, no material loss, and high optical transparency, making it ideal for industries that require both aesthetic appeal and traceability — such as smartphones, displays, optical lenses, and high-end glass components.

This system is fully automated, ensuring consistent marking quality, efficient operation, and high production throughput.

Working Principle

The laser water marking process is based on localized laser energy focusing.
When the laser beam passes through the transparent or semi-transparent material, it is focused precisely within the interior or on the sub-surface, where it induces microstructural changes or refractive index modifications — forming a visible mark or logo that appears like a watermark.

By adjusting the laser wavelength, pulse width, and focus depth, the system can generate 2D or 3D marking effects inside the material, maintaining surface integrity while achieving high visual contrast.

The entire process is controlled through Inte Laser’s intelligent motion platform, vision positioning system, and automated software interface, guaranteeing micron-level accuracy and repeatable performance in mass production environments.

Key Features

1. Fully Automated Control

The system integrates automatic loading, marking, and unloading modules.
Through a one-click operation interface, the entire process is executed automatically, reducing labor dependency and improving production efficiency.

2. High Precision Marking

The machine uses high-stability laser sources and precision galvo scanners to achieve micron-level accuracy, ensuring clear, consistent, and visually appealing watermarks even on fragile materials.

3. Non-Contact Processing

No mechanical stress is applied to the material surface.
This minimizes the risk of cracks, deformation, or contamination, making it ideal for thin or brittle substrates.

4. Permanent and Non-Fading Marks

The laser-induced watermarks are embedded within the material structure, resistant to abrasion, heat, and chemical corrosion — providing permanent identification without affecting transparency.

5. Clean and Eco-Friendly

No chemical etching, ink, or consumables are used.
The laser water marking process is fully environmentally friendly, with zero pollution and minimal maintenance requirements.

6. Intelligent Vision Alignment

Equipped with a high-resolution CCD vision system, the equipment can automatically detect material position and adjust marking coordinates to ensure precise pattern alignment.

7. Flexible Customization

Supports various watermark types — including logos, serial numbers, QR codes, or anti-counterfeiting patterns — and can be customized according to client requirements and production line layouts.

8. High-Speed and Continuous Operation

Optimized scanning algorithms and efficient thermal management allow the system to maintain long-term stable operation under high-speed production conditions.
