What Are The Typical Applications of Laser Marking?

Laser marking technology is an advanced technology that uses laser beams to mark and process objects, and can be used in different processes, such as ablation, engraving, foaming, coloring, dyeing, carbonization, etc. Its advantages lie in non-contact processing, high precision, and high efficiency, so it is widely used in various fields.
This article will introduce you to the working principle of laser marking, and the advantages of laser marking, and deeply discuss the typical applications of laser marking in the fields of industrial manufacturing, automobile manufacturing, medical equipment, packaging and printing, art and jewelry, environmental protection and green manufacturing application.

What is a laser marking machine

Laser marking is the process of marking parts or workpieces using laser technology. The laser beam hits the material and its energy reacts with the material, leaving a permanent mark. The difference in speed, power, and focus on parts on the parts will lead to different laser processes.Specific wavelengths of laser energy are used for different applications and can only be produced by certain types of laser generators. The most common types of laser marking include fiber laser marking, CO2 laser marking, UV laser marking, etc.
Its working principle is based on the properties of laser light and the process of material interaction with laser light. Laser marking is a marking method that uses a focused laser beam to alter the surface of a target. A laser beam is emitted by an oscillator and scanned using a scanning mirror, then a focusing lens is used to focus the beam on the target and mark it by changing the surface. Since laser marking involves using light to alter the target surface, this method is more wear-resistant than ink-based marking, and the markings will not fade over time.

Advantages of laser marking

Compared with traditional marking methods, fiber laser marking has the characteristics of low cost, high flexibility, and durability. Due to its many advantages, the fiber laser marking machine has become an indispensable tool in the field of modern manufacturing and processing. Here are some key advantages of using a fiber laser marking machine:

High precision

Laser marking uses beam irradiation, and the focal spot size can be controlled to be very small, usually at the micron level. This enables laser marking to achieve very fine markings, whether it is text, patterns, or two-dimensional codes, which can be presented on the surface of the material with high precision and clarity.

High-Speed Machining

Laser marking can achieve high-speed marking and marking, because the laser beam can move quickly during processing, and different processing efficiencies can be achieved by adjusting laser power and scanning speed.

Good Durability

Laser-marked graphics and text are durable on many materials and are not prone to abrasion, fading, or exposure to environmental elements, making them suitable for applications requiring long-term identification and tracking.

Multi-material adaptability

Laser marking technology is suitable for a variety of materials, including metals, plastics, ceramics, glass, paper, leather, and more. Different types of laser generators can achieve the best marking effect for different materials.

Non-contact processing

Laser marking is a non-contact processing method. The laser beam directly irradiates the surface of the object through the optical system without touching the object, avoiding the damage and deformation of the object that may be caused by the traditional marking method.

Flexibility

By adjusting the laser parameters and the focal length of the beam, laser marking can achieve different marking effects on different materials, including surface marking, cutting, engraving, etc., with high application flexibility.

No pollution

During the laser marking process, no chemicals are used, and waste gas, wastewater, and waste are not generated, so it is an environmentally friendly and pollution-free processing method.

Typical Applications of Laser Marking

Laser marking can meet almost any of your industrial marking requirements, and has typical applications in industrial manufacturing, automobile manufacturing, medical equipment, packaging and printing, electronic product manufacturing, and the art industry. Commonly used in marking logos, characters, brands, dates, serial numbers, batch numbers, logos, pictures, photos, QR codes, etc. on the surface of metal and non-metal materials.
