Injection molding is the most commonly used manufacturing process for Plastic Parts. The use of injection molding to manufacture various products varies greatly in size, complexity and application. The injection molding process requires the use of injection molding machines, raw plastic materials and molds. The plastic is melted in an injection molding machine and then injected into a mold, where it cools and solidifies into the final part. Injection molding is used to produce thin-walled plastic parts for various applications, the most common of which is the plastic shell. Plastic shell is a thin-walled shell, which usually needs many ribs and protrusions indoors. It is used for various kinds of electric appliances, including electric tools, instrument panels, and consumer electronics. Other common thin-walled products include different types of open containers, such as barrels. Injection molding is also used to produce several daily necessities, such as toothbrushes or small plastic toys. Many medical devices, including valves and syringes, are also manufactured using injection molding Vacuum Cleaner Accessories,Vacuum Cleaner Parts Accessories,Dry Vacuum Cleaner Accessories,Vacuum Cleaner Replacement Accessory Suzhou Dongye Precision Molding Co.,Ltd. , https://www.sjdongye.com
The rapid development of wind power has benefited from the market-oriented operation mode. Before 2005, domestic wind power was dominated by the power sector, there was no market competition, and electricity prices were high and development was slow. In recent years, the country has organized a total of five concession project tenders, through a concession tender for a total of 49 wind farm projects, with a total installed capacity of 8.8 million kilowatts. The market-oriented operation mechanism of wind power not only attracted a large amount of capital into the field of fan manufacturing, but also enabled wind turbine manufacturers to achieve full competition in technology, quality and cost control, and to promote the rapid improvement of domestic wind power technology and management level. In 2009, the National Development and Reform Commission promulgated the four-level benchmark price for wind power sub-regionally based on resource status, which allows investors to further improve the accuracy of economic feasibility assessment of wind farm construction projects. 
Localization of Wind Power Equipment Brings Rapid Improvement of Domestic Wind Power Technology
The localization of wind power equipment has led to a rapid increase in domestic wind power technology and operation quality. At present, domestic wind turbines generally adopt the mainstream technology of the world today, and the world's leading 3MW turbines and offshore wind power projects have settled in China. The unit kilowatt price has dropped from about 7,000 yuan in the early period of the “Eleventh Five-Year Plan†period to less than 4,000 yuan, a drop of 40%.
