According to the latest analysis report issued by the China Environmental Protection Machinery Industry Association, the current period of strategic opportunities for the environmental protection equipment industry is highlighted, and it is expected that the growth rate of the entire industry will exceed 25% in 2013. It is understood that in 2012, under the dual role of national policy support and market demand, the environmental protection equipment manufacturing economy was in a good state of operation and continued to maintain stable growth rates and profit margins. According to the report, for the whole year of 2012, the industrial output value and industrial sales value of 1,063 environmental protection equipment manufacturing enterprises (including special equipment manufacturing for environmental protection and equipment manufacturing for environmental monitoring) that entered statistical standards were 191.379 billion yuan and 187.947 billion yuan, respectively. Yuan, industrial output value increased 19.46% year-on-year, sales output value increased by 19.58%.
In terms of investment, newly added fixed assets last year reached 46.857 billion yuan, an increase of 78.48% year-on-year. With regard to sources of funds, the state budget contained funds of 186 million yuan, domestic loans of 5.151 billion yuan, foreign capital utilization of 677 million yuan, self-raised funds of 66.427 billion yuan, and other sources of funds of 1.688 billion yuan.
The report believes that the economic performance of the industry in recent years highlights the industry-oriented nature of environmental protection equipment manufacturing policies and strong anti-risk capabilities. The 18th National Congress of the Communist Party of China included ecological civilization construction as one of its five priorities for future work. It is expected that there will be a series of policies to support the development of the environmental protection industry in the implementation phase in 2013. The strategic opportunity period for the environmental protection equipment industry will be highlighted, and the industry-wide growth rate is expected to increase. More than 25%.
Power spinning is also called thinning spinning. Power spinning is a non-cutting processing method developed on the basis of ordinary spinning. When spinning, use the tail top to fix the blank on the mold. When the mold rotates, the rotating wheel makes a feeding motion, so that the blank continuously becomes thinner point by point and abuts against the mold to form a part of the required shape. Power spinning realizes the forming of the workpiece by changing the thickness and shape of the blank.
On airplanes, various nose covers, auxiliary fuel tanks, air intakes, gas cylinders, tie rods, slide rails, and actuators are all formed by spinning. In the engine, most of the propeller cap, casing, lip, intake cone, nozzle, nozzle, etc. are also formed by spinning. Such parts have complex structures, special raw materials, and large product sizes. The use of spinning forming can improve the integrity of structural components, reduce welds and component deformation, and reduce the workload of manual calibration. More importantly, due to the increased strength of the material after spinning, the design wall thickness of the parts can be reduced, thereby reducing the weight of the whole machine and improving the reliability of the whole machine.
