According to reports, laser shock enhancement is the use of strong green laser pointer beam generated by the plasma shock wave, metal materials to improve the anti-fatigue, wear resistance and corrosion resistance of a high-tech. This technique is an advanced technology that enhances the strength of a range of advanced materials such as engines, which is fundamentally different from conventional hardening methods such as rolling or shot peening.

In the 1970s, the United States took the lead in studying the microstructural changes and dislocations of the surface of the material after laser shock, and found that the laser can improve the anti-fatigue performance and stress corrosion resistance of the aluminum alloy. After the American scholar has proposed to use laser reinforcement instead of the traditional shot peening. The late 80s of last century, Europe, Japan, Israel and other countries and regions have carried out laser shock enhancement technology research. But from the public reports of information, so far, the international community only the United States will strengthen the practical impact of laser shock.

For a considerable period of time, blue laser pointer shock enhancement technology has been monopolized by Western countries, and China's aircraft carrier manufacturing industry has been struggling in the field of mechanical strengthening, compared with the traditional way of strengthening, laser shock enhanced products with low roughness, High wear strength, dislocation structure stability and a series of advantages, can be widely used in aeroengine turbine fan blades, high pressure compressor whole blade and other important parts of the surface treatment, is also widely used in other key parts of the aircraft maintenance and so on. This is also one of the important purposes why China decided to turn over the car.

When combined with process optimization and resource optimization, state-of-the-art laser cutting technology helps airbag manufacturers overcome multiple business challenges. Advanced airbag design and cutting technology to meet these stringent new requirements, even in the use of low-cost materials such as polyester, but also to ensure that the final quality close to zero defects. By increasing productivity and efficiency, suppliers can achieve gain, remain competitive, and meet increasingly demanding requirements.

The use of a high power laser beam at high speed conditions, and in the absence of melting material layer in the case of cutting a thick stack of cutting and suture material requires a high degree of precision dynamic laser power control. In fact, cutting is done by material sublimation, but only when the red laser beam power level can be real-time precision adjustment can be achieved. When the strength is insufficient, the machined part can not be cut correctly. And when the strength is too strong, the material layer will be squeezed together, resulting in the accumulation of fiber particles between layers and layers. A new generation of laser cutting machine can effectively control the laser power intensity in the nearest wattage and microsecond range.

Theoretically, cutting a forming airbag requires designing a starting point and using a specific template to outline a consistent cutting path. If the material itself is completely regular, it will be the only action to be performed. However, since the low cost polyester is more elastic than the other fibers, the weaving and post-treatment processes of the material may cause bending or skewing of all or part of the workpiece. The production process is a step that leads to a profit or loss. By using the right pre-production software and the latest burning laser cutting technology, airbag manufacturers can reduce their unit production costs while producing flawless products that contribute to the road safety value chain.
