Spray gun is a kind of equipment that uses liquid or compressed air to quickly release as power. There are two types of spray guns: normal pressure type and pressurized type. The spray gun also has a pressure spray gun and an automatic recovery spray gun.
The spray gun includes a gun body and a gun head, the gun body and the gun head are connected by a connecting mechanism; the gun head includes a nozzle with a number of metal round steel plug welded inside the nozzle; the connecting mechanism includes a flange and a chain pin, The nozzle is made into a flat shape; its replacement is more convenient, the cost is lower, and it can effectively prevent the gun tip from falling off and wearing.

Judging from the technological development trend of the machinery manufacturing industry, the proportion of high-efficiency CNC machine tools in China's factories will increase year by year, and the demand for efficient and advanced tools will increase rapidly, while the demand for traditional standard tools will decrease year by year.
The labor productivity of China's manufacturing industry is only 1/3 to 1/5 of that of the United States and Japan. Many Chinese machinery products are cheap but their quality is also low. Recently, due to the appreciation of the renminbi and the rapid increase in domestic labor costs, coupled with the economic cold wave and crisis, it has seriously affected the export of middle and low-end products, and forced us to improve the technological level of the machinery industry as soon as possible, turn the crisis into an opportunity, and forge ahead into a manufacturing powerhouse. . From 2000 to 2008, the rapid development of China's machinery manufacturing industry from 2000 to 2008, the development of China's machinery manufacturing industry is extremely rapid, not only the production of automobiles, machine tools, shipbuilding, power generation equipment, etc., has grown rapidly, but also the product level has been continuously improved. The market share of domestic machine tool output value was 56.3% in 2007 and 61% in 2008. It continued to increase in 2009, reaching 70.1%. In 2008, China's machine tool industry consumed 19.44 billion U.S. dollars worth of machine tools, ranking first in the world; 13.96 billion U.S. dollars worth of machine tools, ranking third in the world; 2.11 billion U.S. dollars worth of export machine tools, ranking sixth in the world; and 7.59 billion U.S. dollars worth of imported machine tools, ranking first in the world. Import and export of machine tools exceeded US$5.48 billion. In 2009, affected by the cold wave of the world economy, the growth rate was reduced, but foreign countries were more affected.
Last year, China’s production machine tools leapt to the top in the world with 5.9 billion U.S. dollars in machine tools, 1.14 billion U.S. dollars in machine tools, and 4.49 billion U.S. dollars in machine tool imports and exports. Machine tools for import and consumption ranked first in the world for eight consecutive years. In 2007, the output of CNC machine tools in China was 123,257 sets, an increase of 32.6% over 2006. In 2008, China's CNC machine tools were affected by the world economic crisis, and the output was 122,211 units, which was basically the same as in 2007. From January to December of 2008, the output of CNC machine tools in China was affected by the economic crisis. After July, the output declined, and it recovered slightly in December. In 2009, the output of CNC machine tools increased significantly, reaching 143,904 units. The market share of domestic CNC machine tools reached 62%. The situation of China's machinery manufacturing industry in 2009 From the perspective of the general environment, since the second half of 2008, the machinery manufacturing industries in various countries have been affected by the financial crisis to varying degrees, and the losses suffered by several major automobile and machine tool producing countries have been particularly serious. The production of automobiles in all countries in the world has dropped significantly. China's auto production and sales have not only declined, but have continued to increase dramatically. In 2009, China’s auto production surpassed the United States and ranked first in the world. In the first half of 2009, the statistics of machine tool production in major countries were as follows: In the first quarter of 2009, the Japanese machine tool industry's orders fell by 84.6%. Domestic demand and exports both fell, affecting a 46.2% decline in sales.
US machine tool orders began to decline in November 2008. New orders received in April 2009 were only US$97.04 million, a decrease of 42% from March 2009 and 78% from April 2008. Orders from January to April 2009 The amount decreased by 71% year-on-year. Germany has revised its forecast for 2009 full-year order trends from a previous decline of 7% to a decline of 10% to 20%. The total orders for German machine tools fell by 70% year-on-year.
China's exports are cheap medium and low-end machine tools, while imports are expensive CNC and precision machine tools.
The current situation of international economic development is still not clear. Faced with the complex and ever-changing domestic and international situation, although the situation of China's machinery industry in the first half of 2012 is good, the trend is not optimistic. Compared with the manufacturing powerhouses in China and the world, there is still a big gap in technology. We must study and improve product quality, increase high-end products, improve manufacturing technology, and strive to innovate. In the post-financial crisis era, the Chinese machine tool industry strives to achieve The transformation from a big country to a powerful machine tool.
