Bellows high-speed molding machine industry in China is gradually developed with the wider use of bellows and, because the corrugated pipe has the environmental protection, energy saving, the advantages of light weight, high strength, corrosion resistance, are widely used in municipal drainage, industrial sewage and other fields, a surge in demand, it's brought opportunities for the development of corrugated pipe forming machine industry.
In our country since the mid - 1980 - s corrugated pipe forming machine imported from abroad, small diameter of 110 mm on the first line is given priority to, its products are mainly used for communication cable to protect casing. In the early ninety s, with the development of the domestic corrugated pipe forming machine, our country gradually from totally dependent on imports to independent production. Due to the expensive foreign products and domestic equipment technical level and continuously improve the quality, the competitive advantage of imported equipment dropped significantly. Especially in recent years, with the domestic corrugated pipe forming machine enterprise rapid rise, foreign corrugated pipe forming machine in our country's market share has fallen dramatically from the original 100% to the current is less than 30%, is mainly used in the minority areas of high-end imports or to provide a key equipment in the form of into the market in our country.
At present, the corrugated pipe is at the beginning of the 21st century high-speed molding machine manufacturing technology has made significant progress, the core technology is close to the foreign advanced level. Double jia thinks as people on the performance of corrugated pipe advantage gradually understand, a further expand application field of bellows, and this will drive the corrugated pipe forming machine industry a new round of rapid development
