With the wide application of plastic products and the rapid growth of their output, plastic machinery has become an important technical equipment in the building materials, packaging, electronic and electrical, automotive, petrochemical, machinery and other industries, and the demand has increased sharply. The plastic machinery industry has become a sunrise industry in China's economic development in the 21st century
with the development of China's plastic industry, the growth rate of plastic machinery industry in recent years has been about 30%, which is one of the fastest growing industries. In 2001, the total industrial output value of China's plastic machinery industry was 8.1 billion yuan and the profit was 590 million yuan. The growth of profit margin was much higher than that of the total industrial output value. In 2001, the total output value of plastic machinery industry was 2.3 times that of 1995, while the profit margin was 4.5 times that of 1995. Among the 194 industries in the national machinery industry, the main economic indicators of the plastic machinery industry are in the forefront
at present, there are nearly 400 major plastic machine manufacturing enterprises in China, most of which are distributed in the southeast coast, the Pearl River Delta and the Yangtze River Delta. The sum of injection molding machine, extruder, extruder production line and hollow blow molding machine accounts for 25mm in our country × 25mm × 2=1250mm2=12.5cm2; The total output value, number of machines and weight of China's plastic machinery industry account for more than 85%, of which injection molding machines account for the largest share among the three varieties, accounting for more than 50%. At present, China's plastic machine products can basically meet the general technical equipment required for the processing of plastic raw materials and the processing and molding of plastic products, and individual products have entered the forefront of the world. However, we should be soberly aware that compared with industrialized countries such as Germany and Italy, China's plastic machinery industry still has a big gap, mainly due to the small variety and low grade of products. Many equipment such as large granulators still need to be imported. In 2001 alone, China imported plastic machinery with foreign exchange of 1.12 billion US dollars, while exported plastic machinery with foreign exchange of only 130 million US dollars
with the wider application of plastic products, plastic machinery for processing polymer materials has become an important production equipment in various manufacturing industries and plays an increasingly important role in the national economy
according to incomplete statistics, at present, the output value of China's plastic machinery industry is about 10billion yuan/year, while the domestic market demand is about 20billion yuan/year, and there is still a lot of market space. It can be seen from the development of the world economy in the past decade that even though the selection of parts was more determined by the comprehensive factors such as vehicle positioning, cost, regulations and performance from 1994 to 1997, the world plastic industry (including the plastic machinery industry) still maintained a growth rate of 3.5% to 4.5%, which shows that the plastic industry has a strong growth force. Some people in developed countries in Europe and the United States predicted that the field of materials in the 21st century is the world of plastics, and China is the largest market in the plastic industry (including the plastic machine industry) in the 21st century. At the same time, the building materials industry, packaging industry, electronic information industry and automobile industry have developed rapidly, increasing the demand for plastics and expanding the market of plastic machinery. First of all, in the building materials industry sector, plastic machinery is mainly used for sewer pipes Production of water supply pipes, door and window profiles, waterproof coiled materials, wire pipes, etc; In the packaging industry, plastic is widely used, involving almost all industry sectors. The variety and performance of plastic mechanical materials are restricted, but it is not suitable for places with heavy loads! Spiral screw rod, also known as trapezoidal screw rod, is mainly used for the production of plastic packaging products such as packaging films, sheets, turnover boxes, etc; In the electrical and electronic information industry, the production of refrigerators, televisions and other products' casings, components, transmission lines, plugs and sockets, as well as the production of various optical discs of information carriers are equipped by the plastic machinery industry; The plastic machinery industry is required to provide production equipment for the production of bumpers, covering parts and interior decorative parts on automobiles; In modern agriculture, the production of greenhouses, double-layer sheds, drainage and irrigation pipe systems, and various agricultural films all need the equipment provided by the plastic machinery industry. The rapid development of these industries will effectively drive the development of plastic machinery industry
on the whole, the market prospect of the plastic machinery industry is closely related to the growth of the plastic industry. The per capita plastic consumption is a comprehensive indicator reflecting the level of a country's plastic industry. Although China is the second largest country in plastic consumption in the world, due to its large population, the per capita plastic consumption is still very low, and the level of plastic machinery industry is far from meeting the domestic plastic market demand. With the development of China's national economy, this gap must be narrowed, which undoubtedly predicts that China's plastic machinery industry has broad space and bright prospects
