High-end pelletizers rely on imported plastics industry urgently need technological breakthrough
Dalian Rubber & Plastics Machinery Co., Ltd. has announced that the large-scale domestic plastic granulator developed by the company will be put into trial production at its new plant in May this year. But I learned that domestic high-end molding machines are still rare in the domestic market, and imported products still account for absolute market share.
Large-scale refinement is the direction of development According to reports, China has cooperated with foreign countries to manufacture several plastic granulators with an annual output of 70,000 tons, but none succeeded. Today's large-scale plastic pelletizing units require a production capacity of over 50 tons per hour, equivalent to an annual capacity of 300,000 to 400,000 tons. It is conceivable that design and manufacturing are very difficult. At present, there are only internationally-designed, manufactured, installed, and commissioned large-scale plastic granulation units such as Japan's Kobe Steel, Japan Steel, and Farrell.
Compared with foreign products, China's plastic granulator manufacturing technology is relatively backward. Through the digestion and absorption of large-scale granulator technology, China has completed the construction drawing design of an annual output of 70,000 to 100,000 tons of polypropylene mixing extruder units, and mastered various aspects of large-scale pelletizing machines and related technologies. Not yet applied. The design and manufacturing level of China's extrusion granulator is quite different from that of foreign countries, and the extrusion granulators for large and medium-sized polyolefin devices still rely on imports.
In recent years, China's plastics machinery manufacturing industry has experienced rapid and sustained growth. This point is reflected in the import and export, not only shows that China's plastic machinery in the production of a great increase, but also shows that the domestic plastic machinery in the quality and technology has significantly improved.
At present, China is a big country in the manufacture of plastic machinery. At the same time, it is a big consumer of plastic machinery, but it is not a plastics machinery power. At present, there are about 400 plastics machinery manufacturers in China, most of which are located in the economically developed southeast coastal areas, mainly in the Pearl River Delta and the Yangtze River Delta. In Tibet, Xinjiang, Qinghai, Ningxia and Hainan, there are still no plastic machinery manufacturers.
With the continuous expansion of the market capacity of China's plastic machinery, the total amount of imported plastic machinery has not been reduced, and it still accounts for about 50% of the total market capacity.
Breakthrough in the technological bottleneck still takes some time. So far, the plastic granulation units in China's large-scale ethylene projects have been relying on imports, precision injection molding machines needed in electronics and communications engineering, and large injection molding machines and large-scale injection molding machines needed in the automotive industry. Layer hollow molding Machine, a large number of biaxially stretched film production equipment used in the packaging industry, multilayer blow molding machines, precision extruders required in the medical and health field, have also been relying on imports. The reason is that the foundation of China's press manufacturing is relatively thin.
On the one hand, there is indeed a gap between the level of China's plastic machinery and the advanced countries, especially some technical difficulties, such as precision injection molding machines, large-scale granulation units, the domestic can not produce, the market is urgently needed, really need to import; on the other hand The performance and quality of domestically-made equipment are not worse than those of imports, and they can fully meet the requirements and are imported from abroad. To solve this problem, apart from further improving its own development and innovation capabilities, the plastics machinery industry also needs to be further improved in terms of management. However, China's press manufacturing companies have been working hard to keep up with international standards and actively participate in international competition. Judging from the speed of development and major economic indicators, the plastics machinery industry ranks among the top 190 industries in the machinery industry. Nowadays, the annual production capacity of plastic machinery in China is about 200,000 sets (sets), ranking first in the world. In Ningbo alone, there are more than 100 injection molding machine manufacturers, of which the Haitian brand injection molding machine series produced by Ningbo Haitian Group Co., Ltd. is complete and exported to more than 30 countries and regions in the world, including developed countries such as Europe and America. 200 million U.S. dollars. According to statistics, China's plastics industry is still in a high growth period. It is estimated that by 2010, the output of China's plastic machinery will reach 500,000 units.
In general, China's general plastic machinery products have excess production capacity. Companies that are currently undergoing technological transformation will need to add more efficient, high-precision equipment and testing equipment in an effort to improve product development and innovation.
There is no diamond drill and it is difficult to live in porcelain. If the press industry wants to “break†again, there is still a lot of homework to do.
