Laser technology is becoming one of the important and indispensable tools in the field of manufacturing and processing today. Not only widely applied in factories and production units, lasers also play an important role in cutting and engraving on many different types of materials. But what laser engraving methods are material processing units using and how do laser engraving machines work? Let’s dig deeper into this issue with Hoa Giang Inox!

What is laser engraving method?
Laser engraving is a machining method that uses laser beams to create patterns or images on the surface of a material. This process is usually done by focusing energy from laser beams on a certain point, creating high temperatures that burn or change the surface structure of that material. Laser engraving can be applied to a variety of materials such as wood, metal, leather and many others, producing diverse and highly accurate results.

Advantages of laser engraving method
Laser engraving method brings many notable advantages. First, the laser beam has the ability to focus high temperatures and high heat density, helping to carry out the engraving process with high efficiency. Laser engraving can be applied to a variety of materials, from metals and alloys to non-metallic materials such as plastic and glass.
During the cutting process, this method minimizes mechanical deformation and produces sharp, highly precise cuts. Not only that, the laser engraving process does not cause noise and creates good working conditions for workers, while reducing the amount of dust generated compared to mechanical methods, significantly improving the working environment.

Popular laser engraving methods
On the market today, there are many industrial laser engraving methods that are widely applied. In this article, Hoa Giang Stainless Steel will introduce to you 4 methods that are considered the most optimal and popular in the processing industry.
Fiber Laser engraving technology
This technology uses light rays transmitted through fiber optic cables and amplified to transmit data. The light beam exiting the fiber optic cable is focused and focused by a lens onto the surface of the material. There are no moving parts that produce light, unlike conventional CO2 laser engravers. This method is ideal for engraving on metal plates and metalworking.

CO2 Laser engraving technology
Laser engraving machines using CO2 technology operate on the energy of CO2 gas and are powered by electricity to create a high-quality light source, which is very popular today. CO2 lasers create smoother surfaces when cutting thick materials. The application of this technology is highly appreciated for its many benefits when engraving on non-metallic materials such as wood, plastic, fabric, leather and many other materials.

Surface Removal engraving technology
This method involves removing the surface layer of the material, creating a colorless incision on the surface of the material to create the desired engraving without affecting the internal structure. This coating can be easily removed to create the desired etching effect.

Color Change engraving technology
This method creates a color change on the surface of the material through a thermal or foaming process, due to the absorption of the laser beam. The result is a deeper and more dramatic color effect on the engraved material. This method allows to create many different colors, depending on the properties of the material.

Principle of laser engraving method
Laser engraving is the process of using laser light to create images, logos, serial numbers, or other information on the product surface. Laser light is projected onto the target to melt, groove, ablate, oxidize, cut or discolor the surface.
Nguyên tắc của phương pháp khắc laser
There are two common types of laser engravers: screen laser engravers and scanning laser engravers.
Screen: In this method, laser light is projected onto the surface of the screen and only the parts that pass through the screen are engraved. The screen allows for high-speed and high-resolution engraving, but requires preparing the screen to suit the content to be engraved, which can increase costs and effort when engraving different patterns.
Scanning: In this method, laser light is projected onto the target and the engraving process is performed in a motion similar to a drawing. Laser light is emitted from an oscillator, then captured by a scanning mirror and projected onto the target surface for engraving. This method allows engraving on non-flat surfaces and the Z-axis height can be controlled.
Laser engraving applications are increasingly popular, and high-speed laser scanning capabilities help solve manufacturing challenges. This has led to an increase in laser scanning systems that allow a greater degree of freedom in engraving.
