China's plastic machinery manufacturing industry needs to seek high-end breakthroughs

China's plastic machinery manufacturing industry has shown a high-speed and sustained growth trend in the past decade. This is reflected in the import and export, which not only shows that the output of China's plastic machinery has increased greatly, but also shows that the quality and technology of domestic plastic machinery have improved significantly

China is a large country in plastic machinery production.

at present, China has about 400 plastic machinery production enterprises of a certain scale, most of which are distributed in the economically developed southeast coast, the Pearl River Delta and the Yangtze River Delta. So far, there are no plastic machinery manufacturing enterprises in Tibet, Xinjiang, Qinghai, Ningxia, Hainan and other provinces and regions. At present, China is a big country in plastic machinery manufacturing and consumption, but it is not a strong country in plastic machinery

the reason is that the foundation of China's plastic machinery manufacturing industry is relatively weak. After the founding of new China, it developed from scratch, from small to large, from weak to strong, and took three historical periods to develop. After the formation period before the 1970s, the growth period in the 1980s and the development period in the 1990s, China's plastic machinery has developed into a large producer and consumer of plastic machinery. Especially after China's entry into WTO, Chinese plastic machinery manufacturers have made great efforts to be in line with international standards, actively participated in international competition, and implemented the strategic policy of "going out" to meet this historical opportunity and challenge. Among the plastic molding machines, injection molding machines, extruders and hollow blow molding machines are the main ones. Their output and output value account for more than 80% of the whole plastic machinery respectively. Among the three products, injection molding machines account for more than 50%. In the 21st century, China's plastic machinery industry has become a new force in the machinery industry

annual output ranks first in the world

in terms of development speed and main economic indicators, among more than 190 industries in the machinery industry, the establishment of professional institutions for basic research project management of plastic machinery ranks first. At present, the annual production capacity of plastic machinery is about 200000 sets, ranking first in the world. In 2003, the output was about 100000 units (sets), including 50000 injection molding machines, accounting for about 50% of the total plastic machinery. There are more than 100 injection molding machine manufacturers in Ningbo alone. Among them, the "Haitian" brand injection molding machines htf80x~htf3600x produced by "Ningbo Haitian Group Co., Ltd." have complete series, mold locking force of tons, and injection molding volume. All these help to improve the safety and effectiveness of electric vehicle batteries, In 2004, the output of plastic machines exceeded 15000 sets and the output value exceeded 3billion yuan. They were exported to more than 30 countries and regions in the world, including developed countries such as Europe and the United States, earning about 200million US dollars in foreign exchange

according to statistics, in January, 2005, the national output of plastic machines was 75000 sets, with a year-on-year increase of 19.05%, still in a high-speed growth period. It is estimated that in 2010, as the former king, China's plastic machinery output will reach 150000-500000 sets respectively. Injection molding machine accounts for about 35%, extruder 25%, hollow blow molding machine 5% and others 35%. In terms of export, injection molding machines accounted for 60.4%, extruders 6.8%, hollow machines 11.7% and others 21.1%; Export foreign exchange earning injection molding machine 74.1%, extruder 8.1%, hollow machine 8.0%, others 17.8%

high precision equipment still needs to be imported

with the continuous expansion of China's plastic machinery market capacity, the total amount of imported plastic machinery has not decreased, accounting for about 50% of the total market capacity. Up to now, the plastic pelletizing units in large ethylene projects in China have been relying on imports; Precision injection molding machines required in electronic and communication engineering, large-scale injection molding machines and large-scale multi-layer hollow molding machines required in the automotive industry, biaxial tensile film production equipment and multi-layer hollow molding machines widely used in the packaging industry, and precision extruders required in the medical and health field have always been imported

on the one hand, there is a gap between the level of China's plastic machinery and that of advanced countries. In particular, some technologies are difficult, such as precision injection molding machines and large granulation units, which cannot be produced in China and are urgently needed in the market, so they really need to be imported; On the other hand, the performance and quality of domestic equipment are not worse than those of imported equipment, which can fully meet the requirements and are also imported from abroad. To solve this problem, the front and other straight sections of C919 fuselage manufactured by AVIC Hongdu aircraft company and the fuselage and aileron large components of C919 large passenger aircraft manufactured by AVIC Xi'an aircraft company have adopted a large number of advanced third-generation aluminum lithium alloy plates. In addition to further improving their own development and innovation capabilities, the management of the country also needs to be further improved. Opportunities and challenges coexist

generally speaking, the production capacity of general plastic machinery products is surplus. At present, enterprises undergoing technological transformation should add some efficient and high-precision equipment and speculation equipment, and strive to improve the ability of product development and innovation. In addition, in recent years, a prominent feature of the plastic machinery industry is that many well-known enterprises in the world have come to China to build factories

foreign enterprises have seized the Chinese market one after another. Although it will play a positive role in the development and base construction of China's plastic machinery, it will also bring severe challenges to domestic plastic machinery manufacturers
