Cement chutes cover mold 1. The increase output, development of high-grade mold present, the world die value of around $ 100 billion, China's mold sales in 2010 reached 112 billion yuan (RMB). Over the past decade, the average annual output value of domestic mold increasing about 18%, higher than the annual growth rate of GPD, however, the total amount of mold still in short supply, the rate of self-made molds with less than 80%, of which middle and low mold oversupply and high-grade Die nearly 50% rely on imports, especially large, sophisticated, complex, long-life flow more cement tank cover mold gap. China is a major importer of the mold, in the amount of imports is equivalent to 25 to 30% of domestic mold output. Due to the rapid development of China's mold industry, stimulating the consumption of domestic steel mold, since the 21 century, domestic steel mold production is increasing rapidly. 2. Adjust the enterprise organizational structure, product mix, technological structure and export structure is an important process mold manufacturing base in the country, belonging to special equipment manufacturing mold manufacturing. Although China has long started making all kinds of cement chutes cover mold mold and use a variety of plastic molds, but not formed long-term industry. Until the 20th century the late 1980s, China's mold industry before entering the fast lane. In recent years, not only state-owned enterprises has made significant progress mold, foreign-funded enterprises, the development of township (individual) mold enterprises is also quite fast. Although China's cement chutes cover mold industry has developed rapidly, but compared with the demand, obviously in short supply, the major gaps focused on sophisticated, large-scale, complex, long-life die in the field. Since the mold accuracy, longevity, manufacturing cycle and production capacity, China and the international average and developed countries there is still a wide gap, therefore, the need to import large quantities each year die. In recent years, cement chutes cover mold industry structure adjustment and increase the pace of structural reform, mainly in large-scale, sophisticated, complex, long-life, high-grade mold and mold standard growth rate than the general mold products; plastic mold and die casting modulus ratio increases; professional mold factory to increase the number of its production capacity; "funded" and the rapid development of private enterprises; shareholding quickening pace of transformation.
