2004-11-08 11 Plastic machinery annual manufacturing capacity of about 200,000 units (sets), a complete range of categories, ranked first in the world.
Currently China's main plastics machinery manufacturing enterprises nearly 400, large and medium-sized enterprises about 200, on the scale of the backbone of the enterprise has 10. Emerging plastics machinery enterprises master high-tech, with scientific and technological innovation, system innovation, management innovation and a series of characteristics, has attracted the attention of domestic and foreign counterparts.
China's plastics machinery enterprises are mainly distributed in the southeast coast, the Pearl River Delta area, including the Ningbo area has the strongest momentum of development, has become China's largest production base of injection molding machines, the annual production accounted for the total annual output of domestic injection molding machines more than 1/2, accounting for the world's 1/3 of the injection molding machine.
Plastic molding industry renewal, technological innovation has also appeared in an unprecedented number of gratifying changes Shantou, Guangdong, most of the enterprises have been the full set of the introduction of Germany, France, Italy and Taiwan Province of China's latest computer automation mold processing technology, greatly improving the mold technical performance, quality grade.
China's plastics machinery, although the rapid development of production varieties are also more, basically able to supply the domestic processing of plastic raw materials and plastic products processing, molding of the general technical equipment required, individual products have also entered the world's forefront, but compared with industrially developed countries, such as Germany, Japan, Italy, China's plastics machinery there is still a gap, mainly in the varieties of small, energy-consuming, low level of control, performance is not stable. Stability and so on.
Currently China's plastics machinery products are mainly concentrated in general-purpose small and medium-sized equipment, low technological content, low-grade products in the 1980s and 1990s, the supply exceeds demand, machinery manufacturing capacity surplus, corporate efficiency decline. Some varieties, especially ultra-precise large-scale high-grade products or blank, still need to be imported. According to 2001 statistics, China's imports of plastic machinery using foreign exchange of 1.12 billion U.S. dollars, while exports of plastic machinery to generate foreign exchange of only 130 million U.S. dollars, imports far outweigh exports.
China's accession to the World Trade Organization (WTO), foreign machinery manufacturing industry to accelerate the transfer of China, the world's leading plastics machinery companies, such as Germany's Demark, Krupp, Battenfeld, Japan's Sumitomo Heavy Industries, and other companies have been "stationed" in China, and some further set up a technology center. The entry of foreign plastics machinery manufacturers to China's plastics machinery industry has brought the development of vitality, but also makes China's plastics machinery manufacturing enterprises are full of opportunities and challenges.
1 Plastic Machinery Development Status and Level
1.1 Openers?
Opening machine that is the double roller refining machine, also known as open refining machine, is the most basic type of equipment in the plastic machinery. It is mainly used for plastic mixing, feeding for the calender and with the refining machine with the use of sheet.
At present, the world's major industrial countries have long formed a series of open refiner production, specifications, size, shape is generally similar. 1990s, China's improvement of the open refiner is to improve the degree of mechanization, increase the safety measures to improve labor conditions and reduce the footprint.
At present, some of the main domestic manufacturers of the opening mechanism to do a lot of improvements, such as the deceleration system is set in the left and right bracket, installed in the receiving tray below, in the frame set up a turning device, the use of hydraulic roller distance and hydraulic safety devices, minimize the weight of the equipment and footprint, and strive to improve the service life of the equipment and so on. At present, the domestic refiner has also formed a complete series of complete varieties and specifications, can fully meet the requirements of users in all aspects. Such as Dalian Bingshan Rubber & Plastic Co., Ltd. took the lead in completing the series of refining and development of openers, openers, rollers and bearings are used in double-row spherical roller bearings, all the transmission gears are concentrated in the closed box, compact structure, high transmission efficiency, good lubrication conditions. The roller pitch adjustment can be single or double at the same time, the operation is convenient and free. In order to reduce the vibration of the machine, the body and reducer are installed separately, and nylon rod pin universal coupling is adopted. This kind of machine has reached the international advanced level and gained the favor of users at home and abroad.
1.2 Dense smelter
Dense smelter is also known as closed plastic refining machine, which is mainly used for mixing of plastics and other materials, etc. For the above purposes, dense smelter is perfectly suited to the needs of the customers. For the above purposes, the refiner can completely replace the opening machine, and production efficiency and automation level greatly improved, labor conditions can be improved. At present, the world's major industrialized countries have formed a series of refiner production, there are basically four types:
(1) to the United States Farrer - Birmingham company produced by the Bunbury-type on behalf of the F-series of refiners;
(2) to the German Werner? Pfleitler company's products represented by the GK series of refiners;
(3) the K series of refiners represented by the British Francis? Shaw company products represented by the K series of refiners;
(4) Moriyama, Japan, represented by the products of the MS series of pressurized refiners.
Since the 1990s, these four types of refiners are fast, high-pressure, large capacity and charging and operation program automation direction, and with microcomputer control. In general, the basic structure of the first 3 series of smelters is similar, the main difference is the configuration of the rotor and the structure of the chamber is different. The main difference lies in the different rotor configuration and chamber structure, while the main structure of the 4th MS series has a big change compared with the first 3 series. The above mentioned types of smelters, chronologically speaking, the latter has both borrowed and inherited from the former, as well as improved and innovated. In the competition in the international market, there are mutual absorption, self-improvement and development between them, each with its own characteristics.
The refiners produced in China basically belong to F series, GK series and MS series, the technical parameters and main performance are comparable with the above three series, and the appearance is also very similar, but the specifications are incomplete, and have not yet formed a complete series.
Internationally, small and medium-sized plastics factories use more pressurized kneading machine. It does not have a top bolt, the use of refining chamber flip discharge, covers an area of small, can be installed on the ground, saving engineering costs. Pressurized kneading machine in Japan has formed a complete series, the smallest refining chamber total volume of 1L, kneading chamber total volume of 3L, the largest refining chamber total volume of 500L, *** 27 specifications.
1.3 injection molding machine
Injection molding machine is one of the main varieties of plastics machinery, accounting for 38% of the total output value of plastics machinery, 1/3 of the plastic products are produced by the injection molding machine.
Currently China's production of injection molding machine manufacturers, according to incomplete statistics has more than 60. The structural form of the injection molding machine has two kinds of vertical and horizontal. According to the production of products can be divided into ordinary and precision injection molding machine. The injection volume of 45-51000g; clamping force of 200-36000kN; processing raw materials are thermosetting plastics, thermoplastics and rubber three. Thermoplastics include polystyrene, polyethylene, polypropylene, nylon, polyurethane, polycarbonate, plexiglass, polysulfone and (acrylonitrile/butadiene/styrene)****polymer (ABS) and so on. From the point of view of processed products, there are single-color, two-color general and precision plastic products. The main manufacturers of the above products have their own series, each with its own characteristics. For example, Guangdong Zhende Plastic Machinery Factory Co., Ltd. produces Jieba CJ series of injection molding machines with two forms of CNC and computer control for each specification. Another example is the HTF80X-HFT3600X series of injection molding machines produced by Ningbo Haitian Machinery Co., Ltd. in Zhejiang Province, which can be used to produce a variety of high-precision thermoplastic products, the machine adopts a linear movement sensor to control injection, mold closing and ejecting, and it adopts a multiple CPU electronic control system, a large-size colorful LED display, and a fully computerized automatic control.
Ordinary horizontal injection molding machine is still the leading direction of the development of injection molding machine, its basic structure is almost no major changes, in addition to continue to improve the level of its control and automation, reduce energy consumption, manufacturers according to the changes in the market is the combination of the series of direction of the development of the same type of injection molding machine configuration, such as a large, medium, small three kinds of injection device, the combination of the standard type and combination type, increased flexibility, expand the scope of use, improve economic efficiency. The use of the scope, improve the economic efficiency.
In recent years, the world's industrially developed countries of the injection molding machine manufacturers are constantly improving the function of the ordinary injection molding machine, quality, auxiliary equipment, supporting capacity, as well as the level of automation. At the same time vigorously develop, develop large-scale injection molding machine, special injection molding machine, reaction injection molding machine and precision injection molding machine, in order to meet the demand for the production of plastic alloys, magnetic plastics, plastic products with inserts.
Injection molding machine is currently China's fastest growing plastic machinery, the level of industrial developed countries with a small gap between the varieties of plastic machines. But mainly refers to ordinary injection molding machine, in the extra-large, a variety of special, special, precision injection molding machine most varieties, some products are still blank, which is the main gap with the industrialized countries.
1.4 Extruder and auxiliary machinery (production line)
Extruder is also one of the main varieties of plastic machinery, accounting for 31% of the total output value of plastics machinery, plastic products processed by extruders accounted for about 1/3 of its total.
Single-screw extruder, whether as plasticizing granulation machinery or molding processing machinery occupies an important position in recent years, single-screw extruder has been a great development. At present, Germany produces large-scale pelletizing single-screw extruder, screw diameter of 700mm, output of 36t/h.
The main symbol of the development of single-screw extruder lies in the development of its key parts - screw. In recent years, people have carried out a lot of theoretical and experimental research on the screw, so far there are nearly a hundred kinds of screws, common separation type, shear type, barrier type, shunt type and wavy type and so on.
From the single-screw development, although in recent years the single-screw extruder has been more perfect, but with the continuous development of polymer materials and plastic products, there will be more characteristic of the new screw and special single-screw extruder. In general, the single-screw extruder to high-speed, high-efficiency, specialization direction.
Twin-screw extruder feeding characteristics, suitable for powder processing, and better than the single-screw extruder mixing, exhaust, reaction and self-cleaning function, characterized by processing of thermally unstable plastics and **** mixing shows its superiority. In recent years, foreign twin-screw extruder has been a great development, various forms of twin-screw extruder has been serialized and commercialized, the production of more manufacturers, roughly categorized as follows:
(1) according to the relative position of the two axes, there are parallel and conical points;
(2) according to the two screw meshing procedures, there are meshing and non-meshing points;
(3) according to the direction of rotation of the two screws, there is no need for the two screws. the direction of rotation of the two screws, there are homogeneous and heterogeneous, and in the heterogeneous there are inward and outward;?
(4) According to the screw rotation speed, there are high speed and low speed;
(5) According to the structure of the screw and the barrel, there are whole and combined.
On the basis of twin-screw extruder, in order to more easily process the poor thermal stability of the **** mix, some manufacturers have developed a multi-screw
extruder such as planetary extruder.
China's twin-screw extruder product line is incomplete, with fewer specifications. Many Chinese plastic products enterprises still use imported twin-screw extruders. in the early 1990s, South China University of Technology invented the electromagnetic dynamic plasticizing extruder, the new theory and concept is notable.
In recent years, China's plastic machinery sets have made great progress. Such as plastic pelletizing machine sets from the host, feed metering, head, pelletizing and recycling system, to heating, cooling, electric control, temperature control system has reached a fairly perfect degree. Thin-walled pipe, thick-walled pipe, winding pipe, corrugated pipe (single, double-walled), composite pipe and other pipe sets of specifications are becoming more and more complete, the level of products, quality continues to improve. In order to meet the needs of multi-layer composite film, composite **** extrusion technology and its molding unit (blown film unit) is also developing rapidly. Such as Qingdao Deyi Li Group recently developed hollow wall winding pipe production line, the production of straight pipe diameter of up to 300mm. and such as Guangdong Jinming Plastic Equipment Co., Ltd. absorbed, the introduction of Germany Leifenhausai company key technologies to manufacture large multi-layer *** extrusion composite film unit, blown film width of a single width of up to 20 m. The unit can be blown film, agricultural film and geomembrane, is a machine dual-use equipment for linear low-density polyethylene, metallocene linear low-density polyethylene, metalized low-density polyethylene, metalized low-density polyethylene, metalized low-density polyethylene and other materials. It is a dual-purpose equipment, suitable for linear low-density polyethylene, metallocene linear low-density polyethylene, low-density polyethylene, high-density polyethylene, (ethylene/vinyl acetate)**** polymer and other raw materials. In addition to the internal cooling technology and ultrasonic monitoring technology adopted in the unit, it also adopts a variety of technologies such as mechanical, electrical, pneumatic and hydraulic at the same time, and a number of technologies have applied for technical patents.
1.5 Blow Molding Machine
In recent years, China's blow molding machine has been developing rapidly and has also formed its own series. In order to contain different solutions for the needs of the production of single-layer, multi-layer containers, the volume of 1-5000L.
Currently, the main models of the newly developed: CNC multi-coordinate hollow molding machine, high-efficiency dual-mode injection and blowing hollow into the machine, direct temperature-regulating type of injection and blowing hollow molding machine, and so on. This kind of machine development trend is summarized as "three a low", namely, automation, high speed, multi-layer and low noise.

2 Market Outlook?
2.1 Domestic Market
"Ninth Five-Year Plan" period, the plastic machinery with the development of petrochemical products, plastic products increase, to reach the "golden" age. After 5-10 years, plastic machinery is still the "sunrise" industry. Some people abroad predicted that the 21st century material field is the world of plastics, and China is the 21st century plastics industry (including plastics machinery industry) the largest market.
Currently China's plastics machinery industry output value of about 10 billion yuan a year, while the domestic market demand of about 20 billion yuan, there is still a lot of space. In addition, it is now recognized that the per capita annual consumption of plastics in a country or region and the status of the plastics industry in the national economy is one of the important symbols reflecting industrial development and progress. China is rich in plastics resources, the main synthetic resin production in the early 21st century amounted to 14,000 tons per year, ranking 4th in the world. It is predicted that China's output of synthetic resins will grow at a rate of 5%-10% during the period of "11th Five-Year Plan". China is a large consumer of plastics, according to statistics, its annual consumption accounts for the world's second, second only to the United States, while China's per capita consumption of only 19kg, ranked 32nd in the world, is 11% of the industrialized countries -20%, it is evident that China's plastics industry, but also the development of plastics machinery has a bright future.
(1) agricultural plastic machinery?
China's 1.3 billion people, 80% in rural areas, agriculture is China's basic industry. Agricultural plastics machinery is in wide demand, the largest demand.
Modern agriculture, greenhouse, double roof, drainage and irrigation piping systems, the production of various types of agricultural film, etc. are required to provide equipment for the plastics machinery industry. Agricultural experts believe that the performance of agricultural covering materials with temperature and moisture, including shed film, film, green feeding film, sunshade, water-saving irrigation with supporting pipes and fittings and other plastic products will be widely used in China. According to the Ministry of Agriculture forecast, by 2005, China's horticultural facilities cultivation area will reach 23 million hm2 or so, the national film coverage area will reach 170 million hm2, including ammonia film, silage film and winding film film forage film, plastic seedling containers, shade nets, insect nets, fishing nets, agricultural products storage and preservation of materials, foam plastic sheets, etc., about 3 million t / a plastic products. Water-saving irrigation with supporting pipes and fittings will be widely used. According to the water conservancy department preliminary planning, to 2005, water-saving irrigation project area will be 16.67 million hm2 on the basis of new water-saving irrigation area of 10 million hm2. It is expected to need a variety of plastic water-saving equipment, such as various types of pipes and fittings, water irrigators, sprinklers, seepage control film, geotextiles, such as 1.7 million t.
(2) construction of plastics machinery
Building Industry Is one of China's pillar industries, the demand for plastic products will continue to rise.
In the construction materials industry sector, plastic machinery is mainly used in the production of downpipes, uppipes, doors and windows profiles, waterproofing rolls, wires, tubes and so on. In recent years the domestic non-toxic, harmless, non-polluting plastic building materials will become the hot spot of market demand in this century. As the country has banned the use of cast iron pipes, replaced by plastic pipes, it is expected that in 2010 the country's new residential indoor 80% of the drainage pipe and 50% of the city's water supply will use plastic pipes. At the same time, the country is vigorously developing plastic doors and windows, plastic doors and windows and plastic pipe penetration rate is expected to reach 30% -50% by 2010, the market share of plastic drainage pipes will be more than 50%. The output of plastic doors and windows will reach 40-45 million m2, accounting for more than 80% of the total number of doors and windows in the country's buildings. At present, plastic pipes and profiles in the construction of pipes and doors and windows in the use of the proportion has reached 30% and 15% respectively, the future demand for the total number will reach more than 800,000t per year. Other plastic products such as wallpaper, floor leather, floor blocks, carpets and waterproofing rolls have also become indispensable varieties of modern building materials.
(3) plastic machinery for the automotive and electronics industries
Auto bumpers, steering wheels, instrument panels, etc. are not injection molded parts. At present, Europe and the United States each car with plastic 90-120kg, of which nylon is about 10kg. today, the automobile manufacturing industry is moving towards reducing the weight of the body, high-speed, low-consumption direction. Expected annual growth rate of automotive plastics for 10% -20%. 2002 domestic production of 3.198 million vehicles, is expected to increase to 5 million in 2005, when the automotive manufacturing industry needs plastic products up to 370,000 t. Varieties of plastics machinery should be developed with the development. Electronics industry in the refrigerator, television and other products such as cases, accessories, transmission lines and plugs and sockets, etc., the production of information carriers of various types of CD-ROM production by the plastic machinery industry to provide equipment. Cables, fiber optic cable insulation and sheath materials have been changed from rubber, lead, paper and other materials to all-plastic materials, with the development of the communications business, the amount will grow. Computers, washing machines, refrigerators, fans, air conditioners, vacuum cleaners, televisions and many other household appliances, the popularity of the growing, so that plastic materials really find a place to use. It is predicted that the future annual demand for engineering plastics only refrigerators, freezers, washing machines, air conditioners and various types of small household appliances will reach about 600,000t.
It is expected that the "Tenth Five-Year" period of the home appliance industry each year to the plastic mold required for the mold volume growth rate of about 10%. Experts believe that large, precise (thin-walled products) injection molds will be welcomed by the market in the future.
(4) plastic packaging machinery
Packaging is also the main field of application of plastics, plastic in packaging materials accounted for the largest share. According to statistics, Japan's total consumption of various packaging materials at an average annual growth rate of 2.8%, of which 4.7% paper, metal 4.9%, glass 3.3%, plastic 7.1%, while cellophane and wood are negative growth. Various packaging materials in the United States growth rate of aluminum 3.1%, steel 1.8%, glass 0.9%, paper 2.2%, plastic 6.4%. 2002 China's plastic packaging materials, the output of the main products totaled 4.01 million tons, 3.5 million tons than in 2001, an increase of 14.2%, accounting for about 1/3 of the total output of packaging materials, ranking first in a variety of packaging materials.
Based on the experience of developed countries, in terms of food, small measurement of plastic packaging accounted for a high proportion, such as the United States, France, Germany, Italy and other commercial food, small packages accounted for 80% of large packages accounted for 20%. At present, China's small packages have just begun. If the international level of advanced countries, at least 1.1 million tons of various plastic substrates are needed. with the development of packaging technology for beverages, pharmaceuticals, detergents, cosmetics, chemicals and other packaging technology, the demand for composite film, packaging film, containers, crates and other packaging supplies is growing. For example, the output of beverages is basically doubled in five years, predicted that in 2005 will reach about 25 million t, of which 50% will use polyester bottles. In addition, convenience foods, dairy products, canned foods, monosodium glutamate, cookies and other kinds of packaging, the annual need for plastic up to several million tons.
So far, China's anti-static film is still mainly imported by the United States, Japan.
In short, due to China's economic macro and micro aspects of the situation tends to be good, social needs will be a stable growth situation, and ultimately will stimulate the growth of packaging consumption. The consumption of plastic packaging products will inevitably promote the plastic packaging machinery technology progress and rapid development.
In summary, it is predicted that the next 5-10 years, plastics machinery will be greater development, the main varieties, categories of plastic calenders and auxiliary machines, single-screw extruders and auxiliary machines, twin-screw extruders (including conical screws and parallel screws) and auxiliary machines, plastic injection molding machine (including two-color injection molding machine, gas injection molding machine, rotary injection molding machine, multi-position footwear rubber and plastic injection molding machine), plastic extrusion wire Cable wrapping unit, plastic extrusion wire drawing, textile unit, plastic extrusion profiles, pipe unit, plastic extrusion blown film unit (including double-layer composite and multi-layer composite blown film unit), plunger extruder, paste PTFE extruder, transfer molding machine, plastic molding machine and the corresponding molds and so on. Among them, blown film, heat preservation shed film unit and extrusion unit, especially blowing the width of 16m above the shed film unit and extrusion diameter of 630mm above the development of large tube unit will play an important role in the production of plastics machinery will be to the direction of the development of economic scale. In order to eliminate environmental pollution, plastic recycling equipment will also have a certain development.
2.2 international market?
China's accession to the WTO, facing new challenges and the development trend of global economic integration, China's plastics machinery industry should be in line with changes in the situation at home and abroad, the use of relevant national policies, and actively adjust the strategy, out of the country, to open up new horizons.
Chinese enterprises to enter overseas, has been included in the "Tenth Five-Year Plan" plan "going out" program strategy. China's foreign investment goals, by 2015 will cultivate 50 large multinational enterprises, among the world's top 500. Plastic machinery industry should be among the large enterprises, in the international arena to develop a wider range of in-depth cooperation and competition.
International market requirements for plastics machinery, different levels, the Western European market for plastics machinery products, the technical level and quality requirements are very high, China is still difficult to be among. Japan's trade protection and technical level is an invisible fortress, China is difficult to break into, even if it breaks into, the export volume is not large. Hong Kong and Macao is China's traditional market, but in recent years the region has formed its own plastics industry, with a certain degree of mechanical manufacturing capacity. The United States, despite the high level of technology, but the requirements are multi-level, in the export of high-grade plastics machinery at the same time, but also imported a lot of their own no and do not want to produce plastics machinery. 1996 U.S. imports of plastics machinery amounted to 495 million U.S. dollars. At present, China's plastic machinery, such as Zhejiang Province, Ningbo Haitian Plastics Machinery Co., Ltd. injection molding machine has entered the United States. Through the improvement of product quality, after-sales service to strengthen the U.S. market will be able to expand with it.
In addition, the Middle East oil-producing countries such as Jordan, Iran, Saudi Arabia and other countries have more foreign exchange earnings, they like to bidding and contracting projects to import complete sets of plastic processing equipment. With China's equipment sets of level of improvement, the market will be able to develop more and more. Changzhou automatic control system engineering company's complete set of woven bag production line has entered the market. Southeast Asian countries such as Indonesia, Thailand, Malaysia, Vietnam and other countries is another traditional market for plastics machinery, it is expected that the future demand will continue to be an upward trend, especially in Vietnam on the demand for plastics machinery is growing rapidly. In the past, China's aid to Vietnam's equipment after decades of use has reached the point where it must be updated. The Russian and Eastern European markets have great potential and are also one of China's major markets. Near the Chinese side of the Far East almost entirely dependent on imports of plastic machinery, South America, Africa is also a potential market for China's exports of plastic machinery.
In order to improve the added value of the product, to capture the market, must be completed as soon as possible the upgrading of plastic machinery products, improve the grade.
Injection molding machine should be completely eliminated relay control, the use of digital programs, programmable open-loop control, the precision injection molding machine using semi-closed loop or fully closed loop control system; hydraulic system using dual pumps and flow, pressure dual proportional valves; the host part of the use of double-cylinder injection and internal turn-over type of five-hinge double-elbow clamping mechanism; the control part of the large-scale injection molding machine to increase the displacement sensors, automatic feeder, mold temperature controller, The control part of the large injection molding machine increases the displacement sensor, automatic loading device, mold temperature controller, automatic mold change by robot, realizing automatic control by microcomputer; the hydraulic system adopts variable pump and accumulator; the host adopts the simple direct pressure clamping mechanism, and the new structure of double template can be developed for the large-scale injection molding machine.
Extruder and auxiliary ① increase the screw length to diameter ratio (L / D> 30), try to use a separate type, barrier type, corrugated type and other new screw, increase speed (maximum speed n> 200r/min), the use of non-stop filter change device; ② frequency conversion speed control, reduce energy consumption, reduce the ratio of power; ③ programmable microcomputer to achieve automatic control of temperature, pressure, speed, etc.; ④ Woven bag production line should improve the drafting device heating precision and drafting speed, the development of new water-cooled devices to adapt to high-speed production, increase the rotary speed of circular knitting machine and reduce energy consumption and noise, improve the quality of the printing press, so that complete sets of equipment on a level; ⑤ blown film units (including multi-layer **** extrusion blown film) should be equipped with automatic feeding, set up a fast non-stop screen and automatic thickness measurement device.
3 Market development?
The world of plastics machinery is moving towards unmanned, intelligent direction. Europe and the United States, Japan and other industrially developed countries and regions of the advanced plastic machinery manufacturing enterprises of the new products are moving towards miniaturization and large-scale, flexible and nimble, automation and intelligence, networking and virtualization, personalization and scale of operation complementary to the development of the new trend. China wants to change the status quo of domestic plastics machinery, in the international community to achieve its size to match the right to speak, and then into the world's plastic machine power, experts suggest that to summarize the experience, to identify gaps on the basis of the following measures:?
(1) Adjustment of corporate organizational structure?
On the whole, China's plastics machinery industry is growing in strength, the level of increasing, but the organizational structure is not ideal, very few large-scale enterprises, small and medium-sized enterprises to occupy half of the country. Small enterprises in the technical force, production equipment or management level are very weak, poor risk resistance. Therefore, China's plastics machinery industry to produce the same type of products should be united, take the road of conglomeration, to participate in the competition.
(2) Increase technical investment
China's domestic research institutions specializing in plastic machinery is too small, engaged in research and design of plastic machinery products is weak, resulting in low technological content of plastic machinery products.
In the "Tenth Five-Year Plan" to "Eleventh Five-Year Plan" period should be enriched, expanding the plastic machine research institutions, focusing on training, the introduction of the use of this area of talent, the development of new technologies, to create their own patented products, in order to improve the plastic machine "value".
(3) the use of international plastic machine results?
Foreign industrialized countries in the plastic machinery industry started early, mastered more plastic machine new technologies, new products and technology patents, China in the innovation and development of products, should try to learn from international experience, the use of the international plastic machine has been the results of the road not to go through repetitive research, development, should be taken to joint ventures, joint ventures, the introduction of other ways, and even the purchase of advanced and mature parts and components, accessories and control system
(4) the use of advanced technology and equipment
Currently, China's plastic machine manufacturers of machining equipment, most of the use of general-purpose machine tools for processing plastic machine parts, low efficiency, unstable quality. Should be replaced by the use of special tools, fixtures, gauges and special machine tools for machining larger batches of plastic machine parts. Only with advanced technology and equipment to improve efficiency, quality assurance and cost reduction.
(5) the development of labor-intensive products
Currently the world's industrial structure in the adjustment, industrial developed countries continue to shift industrial production to capital-intensive and technology-intensive industries, labor-intensive products are being transferred to developing countries and regions. China should take advantage of this opportunity, the development of openers, refiners, calenders, plastic recycling and regeneration equipment and the gap in the edge of the equipment, etc., in order to expand the export of plastics machinery and solve the problem of surplus labor to create conditions.
4 Conclusion?
China's accession to the WTO has further improved the international market environment of China's plastic machinery industry. Plastic machinery industry to seize the opportunity to make full use of the relevant policies, play the local (domestic market) low labor costs and social stability, the advantages of sustained growth in gross domestic product, hard work "internal strength", take effective measures to make the production efficiency has been walking in the first of China's machinery industry in China's plastics machinery industry with a higher average annual growth rate Recreate glory.
