Plastic machinery refers to all kinds of special machinery and devices used in plastic processing industry. Plastic machinery industry is developed with the development of polymer chemistry and plastic processing technology, and gradually become an independent industrial sector. After the Second World War, many plastic raw materials have been produced on a large scale. Instead of metal, wood, glass, paper, fiber and other materials, plastic products have been applied more and more in various sectors of the national economy and people's life. Today, plastics, together with metal, wood and cement, have become the top ten structural materials for modern industrial construction, and the plastic machinery industry has also become an important technical equipment for building materials industry, packaging industry, electrical appliances, electronics, information industry, automobile and other transportation industry, agriculture, light industry, biology, medical treatment, petrochemical industry, national defense and other departments. The upstream industries of plastic machinery industry are mainly steel industry and non-ferrous metal industry, while the downstream industries mainly face packaging industry, light industry, electrical appliances, electronic information industry, building materials industry, automobile industry, etc.

After more than 60 years of development, especially the rapid development since the reform and opening up, China's plastic machinery industry has formed the world's largest industrial system with complete categories, solid foundation, a certain level of technology, which can basically meet the needs of the national economy, and considerable international competitiveness, and has made remarkable achievements. Compared with metal, stone and wood, plastic has the advantages of low cost and strong plasticity. It is widely used in the national economy. The plastic industry occupies a very important position in today's world. Over the years, the production of plastic products has developed rapidly all over the world. The output of China's plastic products has always been in the forefront in the world, among which the output of many kinds of plastic products has been ranked first in the world, and China has become a major producer of plastic products in the world. From 2001 to 2010, the average annual growth rate of China's plastic products output was maintained at more than 15%, and the total output of China's plastic products reached 58.3 million tons in 2010. Although China's total consumption of plastic products has ranked second in the world, the per capita consumption of plastic products is far behind that of developed countries. The data show that the per capita consumption of plastics in China was only 29.5 kg in 2005. In the same year, the per capita consumption of plastics in the United States, Belgium and Germany reached 171 kg, 169 kg and 155 kg respectively, which were 5.79 times, 5.73 times and 5.25 times of the per capita consumption of plastics in China. China's plastic machinery market has been paid more and more attention by foreign enterprises. On the one hand, many large international enterprises continue to increase the depth and breadth of cooperation with China's plastic machinery enterprises, but most of them use the way of merger or purchase of shares to occupy China's plastic machinery market. At present, according to the statistical data of China's Plastic Machinery Industry Yearbook in 2018, from 2011 to 2017, the operating income of Enterprises above Designated Size in China's plastic machinery industry showed a fluctuating upward trend. The development of plastic machinery industry depends on the development of plastic raw material industry and plastic products processing industry. The general development trend of China's plastic machinery is to develop in the direction of combined structure, specialization, serialization, standardization, compounding, miniaturization, large-scale, personalization and intellectualization. At the same time, it should meet the requirements of energy saving, material saving and high efficiency, so as to meet the needs of cost saving of plastic raw materials and plastic products processing enterprises. According to the statistical data of "China plastic machinery market operation dynamic monitoring and development prospect investment forecast report 2020-2026" released by CICC Qixin international consulting, in the first three quarters of 2014, China's Plastic Machinery Enterprises above Designated Size achieved a revenue of 39.010 billion yuan, a year-on-year increase of 9%, and achieved an export delivery value of 6.662 billion yuan, a year-on-year increase of 27%, Plastic machinery industry maintains a good growth trend. In 2017, the operating revenue of Enterprises above Designated Size in China's plastic industry reached 67.045 billion yuan, an increase of 12.54% over the previous year. Benefiting from the continuous expansion of the downstream, the global plastic output value reached 33.9 billion euro in 2015. According to the data, the global plastic machinery market will reach 37.1 billion euro in 2017. Among them, the Asia Pacific region accounts for half of the demand, while the Chinese market accounts for about 20% of the global market. It is predicted that by 2022, the European market for plastic parts (the broader downstream of plastic machinery) will reach 104 billion euro (excluding synthetic fibers, coatings and adhesives). From the perspective of terminal applications, packaging, construction, automobile, home appliances, 3C, medicine are the main downstream applications. The upgrading of downstream plastic processing industry promotes the rapid development of plastic machinery. China's plastic processing industry is developing rapidly, and from the quantity oriented development stage to the stage of improving the development quality, improving the development efficiency and industrial upgrading, which drives the rapid development of plastic machinery and equipment industry. In recent years, the output of China's plastic products has maintained a stable growth. According to the data of the National Bureau of statistics, from 2000 to 2017, the number of Enterprises above Designated Size in China's plastic machinery industry increased from 170 to 402, and the industry's operating revenue increased from 6.644 billion to 67.1 billion, with an annual growth rate of about 15%. In 2017, the total output value of plastic processing special equipment manufacturing industry reached 57.972 billion yuan, a year-on-year decrease of 1.48%. From 2011 to 2017, the profit of China's plastic processing special equipment manufacturing industry showed an upward trend. In 2017, the total profit reached 5.827 billion yuan, a year-on-year increase of 14.8%. The plastic machinery industry is growing rapidly and is expected to reach 100 billion yuan in 2022.

With the continuous promotion of energy conservation, environmental protection and green low-carbon economy, China's per capita plastic consumption will get faster growth, and the development prospect of China's plastic machinery industry will be better. At the same time, China's plastic machinery market is more and more concerned by foreign enterprises. Many large international enterprises not only increase the depth and breadth of cooperation with China's plastic machinery enterprises, but also use the way of merger or purchase of shares to occupy China's plastic machinery market. The development potential and advantages of plastic machinery industry are deepened.
