What materials can CO2 lasers mark?

Introduction

CO2 lasers are a popular choice in various industries due to their versatility and efficiency in marking a wide range of materials. The wavelength of CO2 lasers, typically around 10.6 micrometers, is well absorbed by many non-metallic materials, making them particularly suitable for organic materials. This article provides a detailed overview of the materials that can be effectively marked using CO2 lasers, optimal parameter settings, and solutions provided by the Huawo Laser Company.

Materials CO2 Lasers Can Mark

1. Wood

Wood is a commonly marked material using CO2 lasers due to its organic nature. The laser’s wavelength is efficiently absorbed, allowing for clear, deep engravings. Precise control of the laser power and speed ensures fine details are captured without burning the material.

2. Glass

CO2 lasers can create intricate designs on glass surfaces by causing micro-fractures in the material. This process requires careful control of power levels to prevent shattering.

3. Acrylic

Acrylic is another material that responds well to CO2 laser marking. The laser produces clean cuts and frosted engravings, ideal for signage and decorative items.

4. Paper and Cardboard

Paper and cardboard can be marked quickly and precisely with CO2 lasers, making them suitable for packaging, business cards, and artworks. The speed of marking is critical to avoid burning through the material.

5. Leather

Leather products can be personalized with CO2 lasers, which provide clean, dark markings without compromising the material's integrity.

6. Textiles

CO2 lasers can be used to cut and engrave textiles for fashion and interior design. The laser allows for intricate patterns without fraying the fabric.

7. Plastics

Many plastics, including PVC and ABS, can be marked efficiently. Care must be taken to use appropriate settings to avoid toxic fumes and achieve clear results.

Optimal Parameters for CO2 Laser Marking

The effectiveness of CO2 laser marking depends on adjusting several key parameters:

Power

Typical power settings range from 10W to 100W, depending on the material's thickness and nature. For instance, thicker wood may require a power setting of 60W, while paper might only require 10W.

Speed

Marking speed is crucial for achieving desired results without damaging the material. Higher speeds (500 mm/s) can be used for thin materials like paper, while slower speeds (50 mm/s) are more suitable for glass.

Frequency

The frequency of the laser pulse can vary from 500 Hz to 20,000 Hz. Lower frequencies are often used for cutting applications, whereas higher frequencies are preferable for engraving.

Focus

A precise focus is essential for achieving high-quality markings. The focal point must be adjusted according to the thickness and type of material, typically involving measurements in micrometers.
