Development history of PVC hose extrusion line industry in China

The development of plastic machinery industry is developing rapidly, and its development speed and its main economic indicators are among the top 194 industries in the machinery industry.PVC hose extrusion line manufacturing capacity of about 200 thousand sets (sets), complete categories, ranking number one in the world.
At present, China’s main PVC hose extrusion line manufacturing enterprises are nearly 400, with 200 large and medium-sized enterprises, and 10 backbone enterprises on the scale. The emerging plastics machinery enterprises have a series of characteristics of high and new technology, such as scientific and technological innovation, system innovation and management innovation, which have attracted the attention of domestic and foreign counterparts.
China PVC hose extrusion line enterprises are mainly distributed in the southeast coastal and Pearl River Delta areas, among which Ningbo area has the most momentum of development. It has now become the largest production base of injection machine in China. The annual production amount accounts for more than 1/2 of the annual output of injection machine in China, accounting for the 1/3 of the world injection machine. The upgrading of plastic mold industry has also seen unprecedented changes in technology. Most of the enterprises in Shantou area of Guangdong have fully introduced the latest computer automation mould processing technology in Germany, France, Italy and Taiwan province of our country, which greatly improved the technical performance and quality of the mould.
Although China’s PVC hose extrusion line has developed rapidly and has more varieties of production, it can basically supply the general technical equipment for processing and molding plastic materials and plastic products in China, and individual products are also in the forefront of the world, but compared with developed countries such as Germany, Japan, and Italy, China PVC hose extrusion line There are still some gaps in E machine, which are mainly manifested in varieties, high energy consumption, low control level, and unstable performance.
At present, China’s plastic machinery products are mainly concentrated in the general medium and small equipment, the technical content is low, the low grade product supply of the twentieth Century 80-90 years is more than the demand, the mechanical manufacturing capacity is surplus and the enterprise benefit is down. Some varieties, especially the super fine and high-end products, are still blank and still need to be imported. According to statistics in 2001, China imported plastic machinery to use foreign exchange for 1 billion 120 million US dollars, while export plastics machinery earned only 130 million US dollars, and imports far exceeded exports.
After China’s entry into the world economic and Trade Organization (WTO), the foreign machinery manufacturing industry has accelerated the transfer of China, and some well-known plastic machinery enterprises in the world such as Demark Demark, Krupp, Baden Phil, Japanese Sumitomo heavy industry and other companies have been “stationed” in China, and some have set up a technical center. The entry of PVC hose extrusion line manufacturer in foreign countries has brought vitality to China’s plastic machinery industry, and it also makes China PVC hose extrusion line manufacturing enterprises full of opportunities and challenges.
