NYLON is recognized as the most widely used and known Engineering Plastic in the current market.NYLON PA6 has the best performance, very tough, even at low temperatures, and high surface hardness, mechanical lower shock, and abrasion resistance. Combined with these characteristics and good insulation, and chemical properties, it has become common-level materials. It`s widely used in a variety of mechanical structures and spare parts. Compared to PA6, PA66 own the higher hardness, rigidity, better resistance to wear and heat deflection temperature. Temperature resistance from -40℃ to 110 ℃.

Fiber lasers are a hot spot in the laser field in recent years. In the field of processing, fiber lasers have a tendency to rapidly replace traditional YAG and CO2 lasers. It is widely believed that high-power fiber lasers will be the third-generation state-of-the-art industrial processing lasers. .
The commercial power fiber laser output power continuous power has risen to the order of several kilowatts, up to the order of 10,000 watts. Compared with general lasers, fiber lasers have many unique advantages, such as good beam quality; small size, light weight, maintenance-free; wind cooling, easy to operate; low operating cost, can be used in industrial environments; long life, High processing precision and fast speed; high energy conversion efficiency, which can realize intelligent, automatic and flexible operation. Based on the above advantages, its application fields have been extended to laser cutting and laser welding of metal and non-metal materials such as automobile manufacturing, shipbuilding and aerospace manufacturing.
Recently, the application of fiber laser welding technology in the world of shipbuilding and automobile manufacturing has received considerable attention. In developed countries in Europe and America, about 50%-70% of automotive parts use laser processing technology, and laser welding and laser cutting are the mainstays. Automobile manufacturers such as Shanghai Volkswagen also use laser processing technology to weld parts such as body and box.
Large-scale shipyards in Europe, America and Japan have adopted a large number of laser processing technologies. For example, the United States has widely used high-strength, low-alloy steel T-shaped members on newly-built ships, and laser welding technology has been used to greatly reduce the weight of ships. In order to meet the needs of ocean flow mechanics, hull flat plates are designed to have complex three-dimensional curvature shapes. Laser-assisted flat plate forming technology can replace the laborious, time-consuming and dangerous mechanical heating forming process with good application prospects. Japan's Kawasaki Heavy Industries and other shipbuilding companies have installed high-power laser flat cutting systems. Germany's Meyer Werft also installed four 12KW CO2 lasers for welding hull stiffeners of different lengths.
At present, the development of high-power fiber laser industrial processing equipment is underway in the United States, Europe and other regions, and the secondary development of processing equipment for industrial-grade fiber lasers with 2KW and 6KW output is underway. China has developed a small power series of industrial fiber laser products. Medium and small power laser processing equipment, such as laser marking machines, engraving machines, cutting machines, welding machines, etc., are also widely used in various industries, but the industrial processing application of high-power fiber lasers is still blank, and even in China's shipbuilding industry, lasers have not been used. Processing Technology.
The shipbuilding industry is the focus of Shanghai's new round of economic construction in the next five years. It is one of Shanghai's industrial pillar industries, and various selected shipbuilding technologies and processes are inevitably promoted and applied. As an international city, Shanghai is rich in urban tourism resources. The beautiful scenery on both sides of the Huangpu River has made domestic and foreign tourists forget to return. The use of high-strength light-holding alloy materials (with the obvious advantages of fiber laser processing technology) has been built to meet the needs of the further development of the tourism market. It has been listed as the key development direction of design institutes such as MARIC. . Taking full account of the source of ship design units and manufacturing process standards, cutting into the shipbuilding industry in Shanghai, and through the close cooperation with fiber laser manufacturer IPG, the introduction of high-power fiber lasers, leapfrogging out of a modern and advanced The new model of manufacturing equipment integration, the development of innovative equipment for shipbuilding industry with independent intellectual property rights and the use of the latest international laser technology is of great significance to fill the domestic gap, promote Shanghai shipbuilding pillar industry, and promote the leap-forward development of Shanghai laser industry.
