Laser processing technology has always been a high-tech of the country's key support and application, especially the government's emphasis on revitalizing the manufacturing industry, which brings development opportunities for laser processing technology applications. When the country formulates the medium and long-term development plan, it also lists laser processing as a key supporting technology because it involves national security, national defense construction, high-tech industrialization and the development of science and technology frontiers, which raises laser processing to a high level. The degree of attention will also bring great business opportunities to the manufacture and upgrade of laser processing machines. The material of the marking object can be various types of metals and non-metals. Such as stainless steel, aluminum alloy, plexiglass, plastic, ceramics, synthetic materials, wood, rubber, leather products, paper products, printed circuit boards, various electronic and electrical components, cigarettes, buttons, detonators, metal parts, all the way to food packaging , medicine packaging, even crabs. Its annual sales volume is about 4,000~5,000 units. The laser used is a lamp pump Nd:YAG laser, a glass tube or a metal cavity CO2 laser. In recent years, fiber lasers and all-solid-state lasers are entering the marking production enterprises in batches. The marking machine can mark the part at a fixed position or mark the item on the assembly line. China's production of marking machines is more important than well-known companies such as Dazu Laser, Huagong Laser, Chutian Laser, Daheng Laser, Guilin Xingchen Laser, Zhihengda Laser, etc., and many small and medium-sized enterprises that produce laser marking machines are also important units. Together, China's marking machine market is getting bigger and bigger, the application is getting wider and wider, and it is now starting to export in batches. It is particularly worth mentioning that there are very strong enterprises that develop and produce colorful marking machines on their own. There are many units that order such marking machines at one time. I believe that this innovative product will achieve greater development. Laser processing technology, like remanufacturing and other manufacturing industries, has its irreplaceable advantages and is superior to other processing technologies.

From the annual statistics of the Laser Branch of China Optical Optoelectronics Industry Association, the annual sales of laser processing equipment has been growing at a high speed. For example, in 2003, it increased by 21.6% compared with 2002, and in 2004 it increased by 18% compared with 2003. It is fully explained that laser processing technology has stepped out of the ivory tower from the research and experimental exploration in China, and embarked on the road of practical use. A group of laser processing equipment manufacturers have emerged to produce tens of thousands of laser processing machines that meet the needs of the application. Keep sales growth at around 20% annually. Due to the various propaganda, display, popularization and user training for the domestic market, the market for laser processing has been greatly expanded, giving domestic users the confidence and determination to adopt this advanced manufacturing technology, and the more laser processing is achieved. The more widely used external environment, this is what we often say about the market. The market is driving the sales of laser processing machines, and as such, a chain reaction. As a result of this promotion, more than 200 laser processing machine manufacturers have been formed, employing nearly 20,000 people, of which about 50% of the scientific and technical personnel, about 30% of employees with intermediate and senior titles, has formed a considerable strength. Industrial team. At the same time, it has attracted the attention and follow-up of many laser processing equipment manufacturers around the world, and the domestic market has been internationalized.
First, the rapid development of laser cutting machine products
In the past few years, most of the laser cutting machines sold in China were imported products, and the domestic products accounted for a small share. With the users' deep understanding and demonstration of the characteristics of laser cutting technology, domestic enterprises have turned to the production of laser cutting machines. For example, Shanghai Uniform Prima Laser Equipment Co., Ltd., which has the largest output, has an annual order of more than 100 units and ranks eighth in global production. Others include Huagong Laser Engineering Branch, Jinan Jiemai, Shenyang Prima, and Jiangsu Jinfangyuan. Recently, several well-known laser processing machine manufacturers have also invested in the production of laser cutting machines, including Wuhan Chutian Laser and Han's Laser.
It is estimated that the domestic market has recently sold 300~350 laser cutting machines with 1~4KW, domestic supply can account for more than 200 sets, and other 100 sets are foreign products, from Germany, Switzerland, Japan, South Korea, Belgium and other countries. At present, Swiss Baicha has assembled laser cutting machines in China and has started to sell.
Users of these laser cutting machines include electrical manufacturing, elevators, transportation machinery, petroleum industry, textile machinery, grain machinery, medical machinery, lamps, decoration, packaging, and laser processing stations and research institutes.
CO2 laser cutting technology is one of the most widely used technologies in laser processing. According to my understanding: 12,000 units have been installed in Europe, 11,000 units have been installed in North America, and 10,000 units have been installed in Japan. There are more than 500 installations in Taiwan. The number of installations in mainland China is about 800, and the power is gradually increased from 2000W to 3KW and 4KW. From the above, it can be seen that CO2 laser cutting machine has become the main domestic hot product. With the expansion of the application, the domestic products of high-power CO2 lasers will gradually pass through, which will lead to the rapid growth of laser sales in China.
Second, the laser marking machine (marking machine) will continue to pre-shoot
According to the global statistics on the total sales of laser processing systems, laser marking machines are second only to laser cutting machines. In recent years, the sales volume of laser cutting machines is close to 1/3 of the total. On the contrary, in China, the sales of laser marking machines have accounted for more than 50% of domestic laser processing sales, occupying the domestic market in a large scope, and greatly expanding the applied industrial field. It can be said that it is more than foreign. The application is much broader. The applied industries include electronics industry, automobile industry, tool measuring tools, aerospace, instrumentation, packaging industry, medical products, household appliances, keyboards, panels, advertising signs, ID cards, daily necessities, jewelry and diamonds.
Third, 25W~100W laser processing machine
Here mainly refers to the use of 25W ~ 100W class CO2 laser, plus the XY desktop workbench system based models, but also with Nd: YAG laser plus Mirror integrated processing machine. It can be engraved including engraving, cutting, hollowing, embroidering and cutting. There are many types, low price, wide use and suitability for national conditions. The annual output is around 6,000 units. Widely used in stamps, flexible boards, gifts, advertising, signs, crafts and industrial non-metallic products. Laser processing of horns, glass, plastics, rubber products, bamboo and wood products, synthetic materials, fabrics, leather and other materials. Because it is computer typesetting, self-control, non-contact processing, fast (many faster than manual or other processing methods), high degree of intelligence, easy operation, etc., it occupies the domestic market and is sold to the Middle East, Southeast Asia, South America. It is popular in Eastern Europe and Africa. The production of XY workbench models is highly recognized by Zhejiang Boye Laser, Guangdong Yueming Laser and Wuhan Jinyun Laser. Their rapid rise has formed a production pattern. At present, Boye Laser has built a 35,000 square meter factory building. The laser built a 10,000-square-meter plant, and Yueming Laser not only further expanded its production capacity, but also established a branch in Shanghai. In addition to engraving flexible rubber and bamboo slips, this model also enters laser tailoring garments, leather, embroidery and other work, which makes these enterprise products upgrade and promotes market development. They have already fed, received materials, raw material vacuum adsorption, and automatic camera positioning. The technology of double-head cutting and so on is gradually applied, so that the laser processing equipment can be integrated into the automated assembly line of garment production, so that the products can be intelligently upgraded.
It is worth mentioning that the laser engraving machine is also one of the rapidly developing products. It is a white stereoscopic engraving image formed by laser-induced light scattering that forms a burst point in the vitreous. This technology has recently achieved further development. A certain domestic unit developed a color engraving technology, which can produce red, orange, yellow, blue, purple and other colors in the glass, and soon the product will be put on the market. Add brilliance to the inner carvings.
4. Laser cladding technology and equipment for remanufacturing
Remanufacturing engineering is an engineering practice guided by the product life cycle theory. The entire cost of equipment demonstration, design, manufacture, use, maintenance, and recycling is called the full life cycle cost. Traditionally, only the “first half of life†of equipment is emphasized. (This cycle only accounts for 20-40% of the cost), and is often ignored. "Last half life", that is, the cost of use, maintenance and retirement.
The remanufacturing project of the equipment is an engineering technology that aims to improve utilization rate, save resources, protect the environment, and adhere to sustainable development. The development of remanufacturing technology must incorporate high technology, so that old parts and equipment can be regained high-quality, high value-added products, so remanufacturing is an important technology to achieve leap-forward development and fully comply with national policies. The US's remanufacturing value reached 53 billion US dollars, and the number of employees reached 480,000. They called "re-manufacturing is a potential giant." This aspect of our country has begun.
Laser processing for remanufacturing is the development of phase transformation hardening to laser surface alloying and laser cladding, from laser alloy coatings to composite coatings and ceramic coatings, making laser surface modification technology a remanufacturing Important means. It mainly uses 5KW~10KWCO2 high power laser and its system. The annual sales volume is about 100 units. In this respect, the mainland lasers are used. They apply laser micro-profile cladding technology in practice, which is widely applied to the industrial fields of electric power, petrochemical, metallurgy, steel and machinery. It is important to repair the turbine power rotating device. Parts and components, up to the unit, such as flue gas turbines, centrifugal compressors, screw compressors, large steam turbines, generators, steam turbines, etc., also produce lasers and units, becoming the domestic leading enterprise of this technology. Others are Jin Shikai Laser, Huagong Laser, and United Laser.
Domestic laser processing centers in the form of laser processing stations, such as the Institute of Metals of the Chinese Academy of Sciences, Beijing, Tianjin, Hangzhou, etc., have played a major role in the application of laser processing to remanufacturing.
5. Laser welding technology and equipment
The application of laser welding technology in China is rapidly expanding, and its sales are second only to marking and cutting. It is mainly used in batteries, electrical appliances, instruments, hardware tools and steel, aerospace, automotive and other industries.
There are three main categories of applications: one is for the welding of mobile communications such as mobile phone batteries, and the other is welding of capacitors, electrical appliances, instrumentation components. These welding equipment mainly use Nd:YAG lasers; some of the worktables are multi-station, and the well-known high-volume equipments such as Wuhan Chutian Laser, Huazhong Laser, Dazu Laser and Tianjin Lieneng Laser are produced. BYD, which produces the largest mobile phone battery, has also developed itself; it is self-contained.
The second category is mainly laser welding of diamond saw blades. Diamond saw blades using thermal resistance soldering have been banned in Europe. A large number of CO2 lasers are used to weld the diamond tips to the saw blade substrate. This process meets safety requirements. According to reports, the most expensive diamond cutting tool used in the infrastructure industry is the laser-welded diamond saw blade, which is about $3 billion. This also drives domestic enterprises to invest in this laser welding process and equipment production. China's annual export value is about 30 million US dollars. One of the reasons for the increase in annual export growth rate is that the powder metallurgy of China's synthetic diamond cutter head is better.
In addition, with the expansion of various infrastructure projects, air-conditioning installations and stone industries, the annual demand for diamond saw blades is also about 1 billion RMB. High-end stone processing also requires laser-welded diamond saw blades. Domestically produced laser welding diamond saw blades are larger enterprises such as Huagong Laser and Wuhan United Laser. The production of laser welding saw blade system is Huagong Laser, Wuhan United Laser, Jinan Jiemai, Shanghai Unity Prima and other units, mostly multi-station welding systems.
The third category is laser-welded steel sheets. The applications in this area are mostly in the steel industry (such as steel plate welding, strip welding, etc.), automotive sheet welding (some in steel plants, some in automobile factories) and various The welding of the shell parts and its laser welding system are not stereotyped products, and are mostly “tailor-madeâ€.
Market outlook
Compared with the international laser processing system, China's laser processing system is very different, accounting for only about 2% of global sales. The main performances are: high-end laser processing systems are few or even not; the main lasers are not closed; the micro-laser processing equipment has a large gap; and in these fields, China's production enterprises are steadily entering their reserves, and the domestic application market has a lot of room for development.
It is predicted that in the next 2-3 years, China's sales will double from the 1.5 billion yuan in 2004, which means that it will reach 3 billion yuan. The reason:
First, the state attaches importance to the government departments at all levels are actively paying attention to, planning, and projecting, and various funds are being injected. In particular, the state emphasizes that the main body of the project is transferred from colleges and universities, scientific research departments to enterprises, which promotes independent innovation and technological upgrading of enterprise products.
Second, various domestic manufacturing industries have accepted laser processing technology, which can increase the technical content of their products, speed up product upgrading, and adopt it to achieve the level of “agile manufacturing†and meet the market requirements for “personalized†products.
4. Some well-known laser processing manufacturers in the world have invested and built factories in China; some have adopted domestic joint venture production, and the general trend is to enter one after another, forming an international competition for domesticization.
5. Domestically, the company has gradually passed through the main laser and entered the market. Such as high-power axial-flow CO2 lasers, medium- and small-power metal cavity RF CO2 lasers, semiconductor-pumped all-solid-state lasers, fiber lasers, and multiplier DPLs, high-power diode modules, etc., are gaining momentum, entering the early stage of productization and entering the market. . Create conditions for the new application of domestic laser processing appreciation.
Under the favorable situation that has been established in China, we sincerely hope that all enterprises in the industry will strive to create products with independent innovation, try their best to avoid low-price, low-margin competition, and make domestic equipment embark on a more and more healthy development situation.
