Analysis of the development of China's plastic machinery industry

with the growing of China's plastic machinery industry, especially after entering the 21st century, the rapid growth of domestic demand for plastic products and the increase of exports have effectively driven the development of the plastic machinery industry. The sign of the expansion of the plastic machinery industry is very obvious, and gradually formed a regional structural pattern throughout the country

in recent years, the annual growth rate of China's plastic machinery industry has been around 30%, which is one of the fastest growing industries in China's machinery industry, with an annual output of more than 200000 plastic processing machines, which can basically meet the domestic requirements for the processing of general plastic raw materials and the processing and molding of plastic products

Qian Yaoen, vice president of China Plastics Machinery Industry Association, said in an interview that after the reform and opening up, many enterprises introduced advanced technology and design from abroad and digested and absorbed them by means of joint ventures, cooperation and purchase of production and manufacturing licenses with similar foreign enterprises, which made a significant leap in China's plastics machinery industry, and the products began to initially meet the general needs of the plastics processing industry

at present, China's plastic machinery industry has a complete range of products, forming an industrial pattern with many product categories. China's plastic machinery industry relies on the key development areas of the plastic industry, thus forming a relatively obvious regional structure layout. For example, the production of injection molding machines is relatively concentrated in southern Guangdong, Hangzhou and Ningbo in Zhejiang, Shanghai and Wuxi in Jiangsu; Extrusion production lines are relatively concentrated in Shandong and Shanghai in the East, Wuhan and southern Henan in the middle, Beijing and Dalian in the north; The requirements for thermosetting materials of plastic woven exterior wall external insulation system are not only fire resistance, but also textile equipment is mainly concentrated in Changzhou, Jiangsu and Lanzhou, Gansu; Co rotating twin-screw extruders are mainly concentrated in Nanjing, Jiangsu, Lanzhou, Gansu and Dalian, Liaoning; The mixing equipment is mainly concentrated in Zhangjiagang, Jiangsu and some areas of Liaoning; The production of screw and barrel, the key components of extrusion molding machine and injection molding machine, is mostly in the annual output of 500000 tons of metallurgical grade alumina process optimization, energy conservation and emission reduction project of Chinalco Zhongzhou Aluminum Co., Ltd. in Zhejiang, which is officially put into trial operation in Zhoushan and Nanjing in Jiangsu; All kinds of molds are concentrated in Huangyan Area of Zhejiang Province and some areas of Anhui Province. The initial formation of these industrial layouts has not only provided great convenience for the development of plastic machinery industry, but also opened up a broader world for local construction and development

Ningbo, known as the capital of plastic machinery and mold in China, has become the largest production base of injection molding machines in China, accounting for about 50% of the total annual output of domestic injection molding machines and 1/3 of the total output of injection molding machines in the world. Screws and molds related to plastic machinery have also formed a pattern of intensive production of mechanical testing equipment. Zhejiang Zhoushan Dinghai has become the capital of screws for plastic machinery in China, and Zhejiang Huangyan is known as the hometown of molds in China
