Laser welding has significant advantages over traditional welding technology: the introduction of rapid prototyping technology greatly shortens the time from jewelry pattern to original production; the use of laser marking and laser engraving enriches the methods of jewelry surface treatment, which can further satisfy jewelry Individual needs; laser cutting and grinding can achieve minimum loss. Laser processing technology is playing an increasingly important role in the jewelry industry.
1. Jewelry laser marking
Laser surface compliance technology is a laser processing technology used earlier. It uses a shallow layer of evaporation and ablation material to produce the desired mark. Compared with traditional jewelry marking technology, its main advantages are: 1. Computer control, easier to change graphics; 2. Laser processing is used for fine depiction, which is suitable for high-efficiency and fast-paced requirements of modern production; 3. Material applicability and durability Good, the jewelry precision can be guaranteed without external force; 4. The processing method is flexible and suitable for any mass production; 5. Environmental protection and pollution-free.
2. Jewelry laser welding
Laser welding has the characteristics of high welding strength and speed, low scrap rate, and is widely used in jewelry manufacturing. Compared with traditional welding technology, it has the following advantages: 1. Fast speed, high strength, small deformation, no need for correction and cleaning after welding; 2. Suitable for welding precision workpieces, which can ensure processing quality; 3. High assembly accuracy, which is helpful Develop new technology; 4. Good consistency and stability; 5. Can simplify the work of workpiece repair; 6. Environmental protection and pollution-free; 7. Save processing metal materials.
3. Jewelry laser engraving
Laser engraving works in a continuous or repetitive pulse mode, assisting with protective gas to prevent oxidation during the work process. Laser engraving can be regarded as a straight line extension of laser marking technology. Under proper focus, some laser dots with a diameter of 30um can engrave very small patterns. Engraving in an area of 1mm square is not only beautiful but also has anti-counterfeiting function. .
4, laser rapid prototyping
Laser rapid prototyping technology is a new technology developed on the basis of comprehensive application of various modern technologies (such as computer-aided design, computer-aided manufacturing, computer digital control, laser technology and new materials, etc.). The computer design can be quickly converted into a solid model, in short, it belongs to 3D printing. This technology is mainly used in the jewelry manufacturing industry to form the original jewelry casting mold, lost mold, and wax mold manufacturing. Laser rapid prototyping technology can greatly shorten the product development cycle.
