Laser Applications

Laser applications have become one of the most inquired-about products both domestically and internationally due to the impact of the pandemic. This is because lasers are not only widely used in various industries, but have also replaced many traditional processing methods, offering fast production speed, high marking quality, and low energy consumption.

Laser engraving and laser cutting technologies are rapidly developing and widely used cutting techniques. They are versatile, offer high precision, and do not damage the workpiece. High-energy lasers, after being focused, instantly vaporize the workpiece material to create the cutting or engraving effect. This process has minimal impact on the workpiece surface, preventing deformation and scratches. It produces small gaps (micron-level), making it particularly effective for acrylic materials. The cuts are clean, and the process is non-contact, requiring no contact force, special workpiece clamping, tool wear, or molds. It is suitable for a wide variety of small-batch personalized processing products, as well as high-tech 3C products (electronic products, PCBs, circuit boards, ICs). It provides positive assistance in creating product brand value because the addition of laser engraving process enhances the perceived value of the product. The material of the product itself remains unchanged, but the processing cost of labeling, printing and laser engraving is almost the same, but the quality is greatly improved, and the selling price increases accordingly. This shows that laser engraving will be more widely used in the market in the future due to competition.

Common wavelength types of lasers

CO2 (10600nm), Fiber (1064nm), UV (355nm) and Diode laser (940nm)

Laser engraving technology

Laser engraving technology, specifically, involves using a scanning mirror to scan a target object with laser light emitted from a resonant cavity, thus engraving the image (as shown in the picture below).

Traditionally, 2D laser marking machines use XY-axis control, which means they can only scan laser light on a plane. Now, 3D laser marking machines have emerged that can control the height using a Z-axis scanning mirror, allowing them to mark various three-dimensional objects.

Advantages of laser engraving

1. Capable of high-precision engraving

It can be used to precisely irradiate laser light for high-precision engraving. Even small characters can be recognized, enabling effective quality management.

2. The carving will not disappear.

Labels or prints may peel off or disappear, making it impossible to identify the engraved content, but lasers will not disappear!

3. Multiple engraving methods are available.

This includes techniques such as dissolving the surface, scorching the surface, oxidizing the surface, and discoloring the surface. The key is to choose the appropriate carving method and material!

4. Enables high-speed engraving

High-power laser light output enables rapid engraving, making production more efficient.
