There are many methods of plastic molding. Injection molding is one of them. Injection molding is also called injection molding, which is called injection molding for short. It is a main molding method of thermoplastic. Because it has the advantages of wide application, short forming cycle, high production efficiency, good production conditions, easy mechanization and automation, it plays an important role in the whole plastic forming process.Injection molding refers to injecting granular or powdery plastic from the hopper of the injection machine into the high-temperature barrel, heating, melting and plasticizing to make it a flowing melt, and then under the high pressure of the plunger or screw of the injection machine, it passes through the nozzle at a large flow rate and is injected into the mold cavity. After a period of pressure maintaining, cooling and shaping, When the mold is opened, the Plastic Parts with certain shape and size can be detached from the mold cavity. In this way, the time required to complete an injection cycle can range from a few seconds to tens of seconds, which mainly depends on the size and thickness of the workpiece.

The development of China's valve companies can not be separated from the development of the valve market. In the future, China's valve industry has a promising market, especially in the country's investment and construction, the valve market will be in a steady rising state. At present, China’s policy is to revitalize the equipment manufacturing industry. Valve manufacturing is an important part of the equipment manufacturing industry. Therefore, it will also receive key national support.
The valve industry market benefits from the development of the fixed investment valve industry market. In the long-term future, the valve industry will benefit from the continued development of the state-owned economy and the expansion of fixed investment. In the West-East Gas Transmission Project, West-East Electricity Transmission Project and South-to-North Water Diversion Project, a large number of valves and related products will be used, and this long-term and stable large-scale investment project is the high quality demand in the valve market.
The development of China's valve industry market will also benefit from the advancement of the entire industry. For example, the petrochemical industry, the power industry and the metallurgical industry will all increase the demand for valve products as the industrial scale increases. For example, during the 11th and 5th national period, The implementation of the coal-fired power plant project will bring a demand of 153,000 tons of valves.
The valve industry market benefits from global trade The export volume of China's valve industry has increased year by year in recent years, and domestic valve products have also been increasingly recognized by the international market. With the strengthening of China’s position in international trade and the adjustment of product structure in developed countries, China’s valve products will also gain greater market space. 
China's valve industry has a promising market prospect due to economic development
China's valve companies are numerous and have a wide range of products. They range from gate valves and globe valves to butterfly valves and ball valves. At present, China's valve industry can produce dozens of major categories of valve products. The maximum valve operating temperature has reached 570°C, and the minimum temperature has reached -196 °C, while the ultimate pressure reached 600 Mpa. These have basically met the needs of the domestic low-end market.
