Functional configuration of plastic processing machinery
From the point of view of regional distribution of consumer market, the main consumer market China injection molding machine is gradually spread from south to north.On the export side, occupies an important position in the plastic injection molding machine Chinese export market, accounting for about 60 of total exports, 4%, earnings is accounted for 74, 1%, the main export is fully deserve.Two. ExtruderIn China's plastic processing industry, almost 1/3-1/2 of plastic products are made by extrusion. As the second major categories of products machine, extrusion molding unit production and sales accounted for about 20-25% of plastic machinery, extrusion machine plastic machinery varieties accounted for 30% varieties, the proportion is rising trend year by year.China now has more than 100 extruder production plants, mostly private or township enterprises, mainly in the plastic processing industry developed areas, such as Jiangsu and Zhejiang provinces, Liaoning, Shandong, Guangdong and other coastal areas. The total industrial output value of 124 major extruder enterprises in the country was 38 and 700 million yuan, accounting for more than 70% of the coastal areas. Capable of producing 300 units per year (sets) above extruder manufacturers only three or four companies, most companies can only produce low grade old products, to achieve economies of scale, especially in the level of control, efficiency, accuracy, reliability and complete sets of large gap compared with developed countries.Extrusion equipment made in China is mainly concentrated in small and medium machines. Large, precision extrusion units are mainly imported.Building materials, packaging films and containers as well as commodity production is the main application field market extruder.
In the application, China injection molding machines in general, general plastic products such as toys, stationery, daily necessities, furniture, decoration materials occupy the largest share of the market.Secondly, the injection molding machine mainly used for large household appliances, such as refrigerators, color TV, washing machine, air conditioner, computer shell production, the market using the above Chinese total engineering plastic injection molding machine 40%, domestic high share in this market.Another important field of injection molding machine applications is the production of packaging products, mainly used for PET bottles, plastic bottles, caps and other products. The PET preform injection molding machine market mainly imported equipment control.Optical disk (CD), digital image compact disk (DVD), magnetic disk (MD) and micro optical disk (MDS), as the recording medium, are increasing rapidly all over the world. China has developed CD-ROM injection molding machine, but has not yet 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 NdFeB electronic components, have not been paid much attention by machinery manufacturers due to their low consumption. But with the further subdivision of the market, it is very important to develop the relevant specific models.Similarly, the special injection molding machine for thin-wall or special engineering plastic products is still blank in China, mainly occupied by imported equipment. With the mobile phone shell as the representative of the thin-walled product demand, the development potential of the huge market.
After 80s, China's injection molding machine industry developed rapidly, with an annual growth rate of more than 20%, and gradually formed a processing base mainly in Zhejiang, Ningbo, Guangdong, Dongguan and Shunde. Among them, Ningbo injection molding machine production and sales accounted for more than 60% of the total production and sales. In 2002, the production and sales volume of the whole machine has reached 30000 units. In 2003, it was estimated to reach 35000 units, accounting for about 60% of the total annual output of China's mainland and about 30% of the world's total output. Ningbo is only one city, there is the size of the injection molding machine production enterprise more than 100, including the world's first production and sales of the China Haitian Machinery Co. Ltd. and more than 10 foreign-funded enterprises, involving companies more than hundreds of.China's large backbone injection molding machine manufacturing enterprises are mostly joint ventures, introducing foreign advanced technology and management mode. In terms of technology, the injection molding machines produced in China have been developed from ordinary models to large machines, electronic machines, oil and electric machines and special injection molding machines. Among them, the Haitian developed China's largest clamping force injection molding machine, used in the production of auto parts; Zhen Xiong developed a full electric disk machine for the production of special machines and PET bottles for injection molding special models. Although on the whole, the injection molding machine Chinese production is mainly low-end products, but to the Haitian injection molding machine manufacturing enterprises and Zhenxiong as the representative of the effort to end market development.
I. injection molding machineThe injection molding machine is Chinese production and application of the largest amount of plastic varieties, is the main export China presses.The last century the late 50s, Chinese produced the first injection molding machine, but due to the technical content that equipment is low, commodity can only use general plastics to produce low technical requirements, such as plastic boxes, plastic barrels, plastic pots etc..
