The plastic industry has made great progress and has broad prospects for plastic machinery

the development of the plastic industry has driven the development of the plastic machinery industry. 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. At present, domestic plastic processing machinery can basically meet domestic needs, but compared with the world's advanced level, there is still a certain gap in quality stability and automation. According to incomplete statistics, China has nearly 700 major plastic machinery manufacturing enterprises. In 2005, the output value of China's plastic machinery industry was about 20billion yuan, while the domestic market demand was about 30billion yuan in the same period

the production and sales of the three major varieties are large

in recent decades, China's plastic machinery industry has made considerable progress, with an annual output of more than 100000 plastic processing machines, which can basically meet the requirements of general plastic raw material processing and plastic product processing and molding. In addition to dozens of large-scale plastic enterprise groups with advanced equipment, the vast majority of plastic processing enterprises are mainly domestic equipment

there are still many deficiencies in domestic products in terms of large-scale, precision and high-speed equipment. In recent years, the number of plastic machinery imported by China has also increased rapidly, importing tens of thousands of sets of various plastic machines every year, which is about twice the total output value of domestic plastic machinery, indicating that foreign advanced plastic machinery manufacturers have a relatively obvious competitive advantage in technology, with a range of 2T. Especially in some product fields, imported equipment plays a leading role. For example, the production of heat-resistant PET bottles in China is almost entirely completed by imported equipment; High grade film production equipment is also all imported production lines

in terms of application, the rapid development of building materials industry, packaging industry, electronic information industry and automobile industry has increased the demand for plastics and expanded the market of plastic machinery

in the construction industry, plastic machinery is mainly used in the production of sewer pipes, water supply pipes, door and window profiles, waterproof coiled materials, wire pipes, shading plates, etc; In the packaging industry, plastic machinery is mainly used for the production of plastic packaging products such as hollow containers, various packaging films, sheets, turnover boxes, plastic pallets, etc; In the electrical and electronic information industry, the production of refrigerators, televisions and other products' casings, components, transmission lines, plugs and sockets, and the production of various information carriers are equipped by the plastic machinery industry; Plastic machinery is also widely used in the production of automobile bumpers, covering parts, interior decorative parts, etc; In modern agriculture, plastic machinery and equipment are required for the production of greenhouses, double-layer sheds, drainage and irrigation pipeline systems, and various agricultural films. The rapid development of these industries has effectively driven the development of plastic machinery industry

although the total output value of China's plastic machinery industry accounts for less than 5% of the total output value of China's machinery industry, it plays an increasingly important role in the national economy. In addition to new markets, Mu Du can deal with its favorite former China, and about one-fifth of high energy consumption and low energy production equipment are ready to be eliminated. Experts predict that in the future, the proportion of various plastic processing machines in China's plastic machine market will be: injection molding machines account for 35%, extrusion units account for about 25%, hollow molding machines account for about 5%, and other plastic machines account for about 35%

injection molding machine has become the main force of export

injection molding machine is the largest plastic machine variety in China in terms of output and application, and it is also the main force of China's plastic machine export

in the late 1950s, China produced the first injection molding machine. However, due to the low technical content of the equipment at that time, only general plastics can be used to produce daily necessities with low technical requirements, such as plastic boxes, plastic barrels, plastic basins, etc

After the 1980s, China's injection molding machine industry has developed rapidly, with an annual growth rate of more than 20%, and gradually formed processing bases in Ningbo, Zhejiang, Dongguan, Guangdong, Shunde and other places. Among them, the production and sales of injection molding machines in Ningbo account for more than 60% of the total production and sales of the country. In Ningbo alone, there are more than 100 large and small injection molding machine manufacturers, including China Haitian Machinery Co., Ltd., which ranks first in the world in terms of production and sales, and more than a dozen foreign-funded enterprises, involving hundreds of parts supporting enterprises

at present, most of the large backbone injection molding machine manufacturing enterprises in China are joint ventures, which have introduced foreign advanced technology and management mode. In terms of technology, the injection molding machines produced in China have developed from ordinary models to large-scale machines, all electronic machines, oil and electricity compound machines and special injection molding machines. Haitian has developed the injection molding machine with the largest clamping force in China for the production of auto parts; Zhenxiong has developed a fully electric special machine for CD production and a special machine for PET bottle blank injection molding. Although on the whole, the injection molding machines produced in China are mainly low-end products, injection molding machine manufacturers represented by Haitian and Zhenxiong are striving to develop into the mid-range market

in terms of application, China's injection molding machines are mainly general-purpose, and the production of general plastic products such as toys, stationery, daily necessities, furniture and decoration materials accounts for the largest market share

secondly, injection molding machines are mainly used in the production of large household appliances, such as refrigerators, color televisions, washing machines, air conditioners, computer shells, etc. this market uses more than 40% of China's total engineering plastics, and domestic injection molding machines have a high share in this market

Another important area of application of injection molding machine is the production of packaging products, which are mainly used for PET bottle blanks, plastic bottles, bottles, of which tensile fixtures account for about 80% of the total fixtures, caps and other products. Among them, the PET bottle blank special injection molding machine market is currently dominated by imported equipment

optical disc (CD), digital video disc (DVD), magneto-optical disc (MD) and micro optical disc (MDS), as media for recording data, have seen rapid growth in sales worldwide. China has developed a special injection molding machine for optical discs, but it has not been widely used

some special injection molding machines, such as ceramic injection molding machines for producing fine ceramic components and magnetic injection molding machines for producing neodymium iron boron electronic components, have not been paid attention to by machinery manufacturers due to their small consumption. However, with the further segmentation of the market, it is of great significance to develop relevant special models

similarly, let me discuss its role and intention with my friends. The special injection molding machine for the production of thin-wall or special engineering plastic products is still blank in China, which is mainly occupied by imported equipment. Due to the strong demand for thin-walled products represented by shells in recent years, this market has great development potential

judging from the regional distribution of the consumer market, the main consumer market of China's injection molding machines is gradually expanding from south to north

in terms of export, injection molding machines account for about 60.4% of the total export, and foreign exchange earning accounts for 74.1%, which is a well deserved main export force

extruders are increasing year by year

in China's plastic processing industry, almost one-third or even more than half of plastic products are finished by extrusion molding. As the second largest category of plastic machines, the output and sales of extrusion molding units account for about 20% - 25% of plastic machinery, and the varieties of extruders account for 30% of plastic machinery. There is even an upward trend year by year

there are more than 100 extruder factories in China, most of which are private or township enterprises, mainly concentrated in areas with developed plastic processing industry, such as Jiangsu and Zhejiang, Liaoning, Shandong, Guangdong and other coastal areas. The total industrial output value of 124 major extruder enterprises in China is 3.87 billion yuan, accounting for more than 70% in coastal areas; There are only threeorfour manufacturers with an annual output of more than 300 extrusion units. Most enterprises can only produce low-grade old products, which is difficult to form a scale. Especially in the control level, efficiency, accuracy, reliability and completeness, there is a big gap compared with developed countries

extrusion molding equipment produced in China is mainly concentrated on general small and medium-sized general machinery. Large and precise extrusion units are mainly imported

building materials, packaging films and containers, and the production of daily necessities are the main application markets of extruders
