Introduction

CO2 laser marking is a widely used process in various industries to mark ink and other materials. This article provides a detailed explanation of how CO2 laser marking functions specifically on ink. Huawo Laser provides advanced solutions for this process. Relevant parameters and numerical analyses are also discussed.

CO2 Laser Marking Overview

The CO2 laser marking process employs a carbon dioxide laser to etch or engrave materials by altering the surface properties of the material. It is preferred for its precision, speed, and ability to produce high-quality marks, particularly on organic materials.

Mechanism of CO2 Laser Marking on Ink

When CO2 lasers interact with ink, the laser energy is absorbed by the ink particles. The absorption of this energy causes rapid heating, which leads to the evaporation or ablation of the ink. This leaves behind a precise mark on the substrate. The effectiveness depends on the ink's composition, the laser's wavelength, power, and speed.

Laser Parameters

• Wavelength: 10.6 micrometers
• Power: Adjustable between 10W to 150W
• Speed: Can be set up to 7000 mm/s

Ink Composition

The ink's chemical properties, such as its absorbance rate at the laser's wavelength and thermal decomposition temperature, play a crucial role in the marking process. Organic inks typically react better to CO2 laser marking due to higher absorption rates.

Huawo Laser Company Solutions

Huawo Laser specializes in providing tailored CO2 laser marking solutions. Their systems are designed to cater to specific industrial needs, offering customization in laser power, marking speed, and system integration.

Parameters and Numerical Analysis

Various parameters influence the quality of laser marking on ink, including laser power and speed. Experiments show that increasing power improves marking depth but may reduce precision if not balanced properly with speed. A typical balance for high-resolution marking involves a power setting of 40W at a marking speed of 5000 mm/s.

Experimental Data

Studies demonstrate that at 40W power, the optimal marking depth is achieved with a speed of 5000 mm/s, providing a resolution of 1000 dpi. Deviations in speed can lead to either incomplete marking or excess thermal impact on the substrate.
