Laser engraving technology is a processing technology that uses high-power density focused laser beams to act on surface or interior of materials, causing the materials to vaporize or undergo physical changes to achieve the purpose of engraving or cutting. Below is an introduction to some materials and their laser engraving technology methods:

1. Wood
Wood is one of the common materials in laser engraving, especially light-colored woods such as bir, cherry, or maple, which can be well vaporized by lasers and are suitable for engraving. During engraving, attention must be paid to the laser power and engraving speed to avoid burning the wood. Typically, the engraving depth of wood is not deep, generally within 5mm. For dense woods hardwood, higher laser power may be needed. After engraving, the wood surface can be cleaned with a damp cloth.

2. Acrylic (Organic Glass)

Acrylic is widely used in the advertising industry, and laser engraving can make its products more three-dimensional. When engraving on the back, the graphics need be mirrored first, and the engraving speed should be fast and the power low. When cutting, a blowing device should be used to improve the quality of the. It is noteworthy that when cutting organic glass, the operator should not leave because flames may occur during cutting.

3. Dual-Color Board
Dual-color board an engineering plastic composed of two or more layers of colors, specifically for engraving. The effect of laser engraving on dual-color boards is very good, with edges and no melting marks. The power should be moderate during engraving to avoid melting marks. If cutting is needed, it can be done in multiple steps to the edges of the cut material are smooth.

4. Metal
Metal materials such as stainless steel, carbon steel, and aluminum can all be laser engraved. For steel and carbon steel, laser engraving machines can perform marking and engraving processing. For aluminum, laser engraving machines can perform precise engraving and cutting., although copper itself is not easily engraved by lasers, the special paint film on the surface of copper can be vaporized by lasers, revealing the underlying copper plate achieve an engraving effect. For metal materials, laser engraving usually requires higher power and more precise focus control.

5. Glass
Laser engraving machines perform shallow engraving and marking on glass, creating unique glass artworks. During engraving, the laser power and engraving speed need to be adjusted according to the and hardness of the glass. At the same time, appropriate protective measures should be taken to ensure the safety of the operator.

6. Other Materials
In addition the above materials, laser engraving technology can also be applied to ceramics, silicon wafers, films, stones, and other materials. For ceramic materials, engraving can create exquisite patterns and textures; for silicon wafers and film materials, laser engraving can perform micro-hole drilling and precise cutting; for stone, laser engraving can perform shallow engraving and decoration.

In summary, laser engraving technology has wide applicability and can be used for engraving and cutting materials. When choosing a laser engraving machine, the characteristics of the processed material and the processing requirements should be considered. At the same time, safety and protective should also be paid attention to during operation.
