Analysis and Prospect of the hottest plastic machi

Analysis and outlook of China's plastic machinery market

I. market outlook

1 During the Ninth Five Year Plan period in the domestic market, plastic machinery reached the "golden" era with the development of petrochemical products and the increase of plastic products. In the following years, plastic machinery is still a "sunrise" industry. Some people abroad predict that the field of materials in the 21st century will be the world of plastics, while China is the largest market for the plastic industry (including plastic machinery industry) in the 21st century

at present, the annual output value of China's plastic machinery industry is about 10billion yuan, while the domestic market demand is about 20billion yuan, there is still a lot of room. In addition, it is now recognized that the per capita annual consumption of plastic in a country or region and the position of the plastic industry in the national economy are one of the important symbols reflecting industrial development and progress. China is rich in plastic resources. At the beginning of the 21st century, the annual output of main synthetic resins reached 14000 tons, ranking fourth in the world. It is predicted that from now on to the "Eleventh Five Year Plan" period, China's output of synthetic resin will increase by 5% - 10%. China is also a big consumer of plastics. According to statistics, its annual consumption accounts for the second in the world, second only to the United States, while China's per capita consumption is only 19kg, ranking 32nd in the world and 11% to 20% of the industrial developed countries. It can be seen that China's plastic industry is still in great development, and the prospect of plastic machinery is broad

(1) agricultural plastic machinery □

China has 1.3 billion people, 80% of whom are in rural areas. Agriculture is China's basic industry. Agricultural plastic machinery has a wide range of needs and the largest demand

in modern agriculture, the production of greenhouses, double-layer roofs, drainage and irrigation pipeline systems, and various agricultural films all need the equipment provided by the plastic machinery industry. Agricultural experts believe that agricultural covering materials with the properties of increasing temperature and preserving moisture, including plastic products such as greenhouse film, mulch film, green feed film, sunshade, supporting pipes and pipe fittings for water-saving irrigation, will be widely used in China. According to the prediction of the Ministry of agriculture, by 2005, the cultivation area of horticultural facilities in China will reach about 23million Hm2, and the coverage area of plastic film in China will reach 170million hm2. There are also forage films including ammoniated film, silage film and wrapping film, plastic seedling containers, sun shading, insect prevention, fishing gear, agricultural products storage and fresh-keeping materials, foam plastic plates, etc., which require about 3million T/a of plastic products. Supporting pipes and pipe fittings for water-saving irrigation will be widely used. According to the preliminary planning of the water conservancy department, by 2005, the water-saving irrigation area will be increased by 10million hm2 on the basis of the current 16.67 million Hm2. It is estimated that 1.7 million tons of plastic water-saving equipment will be needed, such as all kinds of pipes and fittings, emitters, sprinklers, anti-seepage films, geotextiles, etc

(2) plastic machinery for construction

the construction industry is one of China's pillar industries, and the demand for plastic products will continue to rise

in the building materials industry sector, plastic machinery is mainly used for the production of sewer pipes, water supply pipes, door and window profiles, waterproof coiled materials, wires, pipes, etc. In recent years, domestic non-toxic, harmless and pollution-free plastic building materials will become the hot spot of market demand in this century. As the country has expressly banned the use of cast iron pipes and replaced them with plastic pipes, it is expected that 80% of the indoor drainage pipes of newly-built residential buildings and 50% of the urban water supply will use plastic pipes in 2010. At the same time, the country is vigorously developing plastic doors and windows. It is expected that by 2010, the popularity of plastic doors and windows and plastic pipes will reach 30% - 50%, and the market share of plastic drainage pipes will exceed 50%. The output of plastic doors and windows will reach 40-45 million m2, accounting for more than 80% of the total number of building doors and windows in China. At present, the proportion of plastic pipes and profiled materials used in construction pipes and doors and windows has reached 30% and 15% respectively, and the total demand in the future will reach more than 800000 tons per year. Other plastic products such as wallpaper, floor leather, floor tiles, carpets and waterproof rolls have also become indispensable varieties of modern building materials

(3) plastic machinery for automobile and electronic industry

all bumpers, steering wheels, instrument panels, etc. of automobiles are injection molded parts. At present, each vehicle in Europe and the United States uses kg of plastic, including about 10kg of nylon. Nowadays, the automobile manufacturing industry is developing in the direction of reducing body weight, high speed and low consumption. The annual growth rate of automotive plastics is expected to be 10% - 20%. The domestic automobile production in 2002 was 3.198 million, and it is expected to increase to 5million in 2005. At that time, the automobile manufacturing industry will need 370000 tons of plastic products. The varieties of plastic machinery should also be developed accordingly. In the electronic industry, plastic machinery industry provides equipment for the production of refrigerators, televisions and other products' casings, accessories, transmission lines, plugs and sockets, as well as various optical discs of information carriers. The insulating and sheathing materials of cables and optical cables have changed from rubber, lead, paper and other materials to all plastic materials. With the development of communication industry, the consumption will increase. The popularity of computers, washing machines, refrigerators, electric fans, air conditioners, vacuum cleaners, televisions and many other household appliances is growing, making plastic materials really find a place to use. It is predicted that in the future, the demand for engineering plastics for refrigerators, freezers, washing machines, air conditioners and all kinds of small household appliances will reach about 600000 tons per year

it is estimated that during the Tenth Five Year Plan period, the number of molds mainly plastic molds required by the household appliance industry will increase every year, and if there is any loosening, the length rate will be about 10%. Experts believe that large and precise injection molds (thin-walled products) will be welcomed by the market in the future

(4) plastic packaging machinery

packaging is also the main field of plastic application, and plastic accounts for the largest share in packaging materials. According to statistics, the average annual growth rate of the total consumption of various packaging materials in Japan is 2.8%, including 4.7% of paper, 4.9% of metal, 3.3% of glass and 7.1% of plastic, while cellophane and wood have negative growth. The growth rate of various packaging materials in the United States is 3.1% for aluminum, 1.8% for steel, 0.9% for glass, 2.2% for paper and 6.4% for plastic. In 2002, the total output of major products of plastic packaging materials in China was 4.01 million tons, an increase of 14.2% over 3.5 million tons in 2001, accounting for about 1/3 of the total output of packaging materials, ranking first among all kinds of packaging materials

according to the experience of developed countries, in terms of grain, the proportion of small-scale plastic packaging is very high. For example, in the United States, France, Germany, Italy and other commodity grains, small packaging accounts for 80% and large packaging accounts for 20%. At present, small packaging in China has just started. According to the level of advanced countries in the world, at least 1.1 million tons of various plastic substrates are required. With beverages, drugs, washing supplies process "With the development of packaging technology for cosmetics and chemical products, there is an increasing demand for packaging supplies such as composite films, packaging films, containers and turnover boxes. For example, the output of beverages is basically doubled in five years, and it is predicted that it will reach about 25million tons in 2005, of which 50% will use polyester bottles. In addition, plastic packaging for convenience food, dairy products, canned food, monosodium glutamate, biscuits and other kinds of packaging needs millions of tons of plastic every year.

So far, China's antistatic films are mainly imported from the United States and Japan

in a word, as China's macro and micro economic situation is getting better, social needs will show a stable growth situation, which will eventually stimulate the growth of packaging consumption. The booming consumption of plastic packaging products will certainly promote the technological progress and rapid development of plastic packaging machinery

to sum up, it is predicted that plastic machinery will achieve great development in the next years. The main varieties and categories include 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 machines (including two-color injection molding machines, gas assisted injection molding machines, rotary table injection molding machines, multi station rubber and plastic injection machines for shoes), plastic extrusion wire and cable wrapping units, plastic extrusion wire drawing Textile unit, plastic extrusion profile and pipe unit, plastic extrusion film blowing unit (including double-layer composite and multi-layer composite film blowing unit), plunger extruder, paste PTFE extruder, transfer molding machine, Blister molding machine and corresponding molds, etc. Among them, the development of plastic film blowing, heat preservation greenhouse film unit and pipe extrusion unit, especially the greenhouse film blowing unit with a width of more than 16m and the pipe extrusion unit with a diameter of more than 630mm, will play an important role, and the production of plastic machinery will develop in the direction of economic scale. In order to eliminate environmental pollution, plastic recycling equipment will also have a certain development

2. After China's entry into WTO, China's plastic machinery industry is facing new challenges and the development trend of global economic integration. China's plastic machinery industry should comply with the changes in the situation at home and abroad, make good use of relevant national policies, actively adjust strategies, go abroad and create a new situation

Chinese enterprises' overseas expansion has been included in the "going out" strategy of the tenth five year plan. Among China's foreign investment goals, 50 large multinational enterprises will be cultivated by 2015, ranking among the world's top 500. Large enterprises in the plastic machinery industry should join them and carry out more extensive and in-depth cooperation and competition on the international stage

the international market has different requirements for plastic machinery, with different levels. The Western European market has high requirements for the technical level and quality of plastic machinery products, and China is still difficult to join. Japan's trade protection and technological level are an invisible fortress, which is difficult for China to break in. Even if China breaks in, its export volume is not large. Hong Kong and Macao are China's traditional markets, but in recent years, the region has formed its own plastic industry and has certain machinery manufacturing capacity. Although the United States has a high level of technology, its requirements are multi-level. While exporting high-grade plastic machinery, it also imports many plastic machinery that it does not and does not want to produce. In 1996, due to the changes in the real environment, the amount of plastic machinery imported by the United States was 495million US dollars. At present, China's plastic machinery, such as the injection molding machine of Zhejiang Ningbo Haitian Plastic Machinery Co., Ltd., has entered the United States. Through the improvement of product quality and the strengthening of after-sales service, the U.S. market is bound to expand

in addition, oil producing countries in the Middle East, such as Jordan, Iran, Saudi Arabia and other countries, have more foreign exchange income. They like to import complete sets of plastic processing equipment through bidding and contracting projects. With the improvement of the complete set of equipment in China, the market development ability will be greater and greater. 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 are another traditional market for plastic machinery. It is expected that the demand will continue to rise in the future, especially in Vietnam, where the demand for plastic machinery is growing rapidly. In the past, after decades of use, the equipment aided by China to Vietnam has reached the point that it must be updated. Russia and Eastern Europe have great market potential and are also one of China's major markets. Plastic machinery in the Far East, close to China, is almost entirely imported. South America and Africa are also potential markets for China to export plastic machinery

in order to improve the added value of products and occupy the market, we must complete the upgrading of plastic machinery products as soon as possible and improve the grade:

the relay control of injection molding machine should be completely eliminated, and the digital program and programmable open-loop control should be adopted, and the semi closed-loop or full closed-loop control system should be adopted for precision injection molding machine; The hydraulic system adopts double pumps and flow and pressure double proportional valves; The main machine adopts double cylinder injection and inverted five hinge double elbow mold closing mechanism; Add displacement sensor, automatic feeder, mold temperature controller and manipulator to the control part of large injection molding machine to realize microcomputer automatic control; The hydraulic system adopts variable pump and accumulator; The main machine adopts a simple direct pressing mold locking mechanism, which can be opened for large injection molding machines
