Date：2014/8/4 16:11:47

         1 Overview
         Plastic processing machinery have vertical injection molding machine, extrusion molding machine, blow molding injection molding machines, injection molding machines heat (including vacuum and compressed air injection molding machine), vertical injection molding machines, injection molding machines rolling, foam injection molding machines, a wide range . In Japan, the production of plastic injection molding machine injection molding machine to yield maximum. According to 1988 statistics MITI yield vertical injection molding machine plastic machinery accounted for 69.8% of total output.
         Japan is in the Second World War began trial production of plastic vertical injection molding machine, and the actual production of plastic vertical injection molding machine is started after the war.
         Early production of Japanese vertical injection molding machine are as follows:
         From 1946 to 1950 ...... 175
         1951_ ~ 1955 ...... 866 stand
         1956 ............. 535 stand
         1957 ............. 887 stand
         1958 ............. 761 stand
         1959 ............. -
         1960 ............. 981 stand
         From the beginning of 1961, with the rapid development of Japan's petrochemical industry dagger, vertical injection molding machine production also appeared during the high-speed fat people, as follows:
         1961 ............. 1539 stand
         1962 ............. 1534 stand
         1963 ............. 2678 stand
         1964 ............. 2534 stand
         1965 ............. 2065 stand
         1966, 2968 stand ...........
         After 1967 is shown in Table 1.
         1955 Japan 40,000 tons of thermoplastic resins, thermosetting resins 50,000 tons, therefore, is a thermosetting plastic injection molding machine vertical injection molding machine in the majority.
         1956 vertical injection molding machine production units for 1417, compared with vertical injection molding machine (535 units) much more. Vertical injection molding machine production up to 1961, for two of the 82 units, but then gradually reduced, in 1988 the production of only 196 units. Vertical injection molding machine producing rapid growth with the rapid growth of thermoplastics and thermosetting resins by injection compression molding less Ge type to shift its growth as shown in Table 1. Two vertical injection molding machine manufacturer in Japan and produced copies of 1955 almost vertical injection molding machine manufacturers are professional factory, but from 1965 onwards, machine tools, shipbuilding, heavy machinery and other well-funded companies, began producing vertical injection molding machine, the main technology introduced from instruct outside. Subsequent period, the added vertical injection molding machine factory production ranks much,: but after 1974 years ago, the number of new entrants to the enterprise began to increase. Currently, the emergence of vertical injection molding machine specialized in producing big wide, and industry manufacturers and professional coexistence among small and medium manufacturers, a total of 35 companies.
         2.1 Our use of technology companies: Tertiary Industry, mountain Seiki, Lin Japan industrial, letters and Seiki, produced by high-taek, Seiki Takahashi, Tanabe industrial companies, Tabata industrial machinery, chemical machinery Central , craft plastic, Toyo Machinery & Metal, Nissei Plastic Industrial, back room Iron Works, Mitsubishi house Seiko Matsuda Seisakusho.
         2.2 to Our technical start, followed by the introduction of foreign technology: Kawaguchi Tekko (England C onair a C hurehil lL td.), Toshiba Machine (Federal Republic of Germany B attenfel dM asehinenfabrik G nt b H), MEIKI (U.S. N ewbury I ndustries I ne.).
         2.3 directly depend on the introduction of foreign technology start: Ube Kosan (U.S. B org a W arner), Kobe Steel (U.S. F arrel M aehinery G ro "p US MC orporation), Sumitomo Heavy Industries (Switzerland N etstal M aehinery) Niigata Iron Works (Federal German company), Japan Steel Works (Federal Republic of Germany a r - Bu urg W erk, K rauss an M affei K unstst -offteehnik G ob H), Mitsubishi Heavy Industries (U.S. a uto dish atik M asehinebau L td.).
         New Enterprise 2.4 1984 after: Aoki Seisakusho, A mada, Doomsday a K rauss M affei (Federal Republic of Germany K rauss M affei K unst .tofftee -hnik), Komatsu, TSUGAMI (Fortress Seiki), Toyoda Gosei, Japan shaft manufacturing (Canada T eeh Tony 1r e company), F anue (U.S. C ioeinn -ati M ilaeron I ne), Matsushita Electric Industrial, modern machinery manufacturing (tree Research industry). (In brackets by the introduction of technology manufacturers). Number of units produced, in 1989 was the highest 15,341 units. The top four companies accounted for 60% of the total number of units produced, followed by the four companies accounted for about 30% of the total number of units produced. Before eight companies namely 90% of the total production volume, uneven distribution is evident.
         3 affect vertical injection molding machine industry
         Electronic, electrical, automotive vertical injection molding machine is affecting the development of the Japanese industry. 1985 industry statistics show that the highest value of the industry are: electrical machinery manufacturing, 41 trillion yen; automotive and other transportation equipment industries with machinery, 35 trillion yen, the food industry, 21 trillion yen, the chemical industry, 19 trillion yen, steel, 15 trillion yen, metal products, 13 trillion yen, plastic products and beverages, animal feed, tobacco, oil and coal products industry roughly about 8 trillion yen more fiber, cloth, paper and pulp and paper processed products, precision machinery is more in the Second Industrial. Plastic products output in 8 trillion yen, an injection products accounting for about 5 seventeen trillion yen, showing the proportion of injection molding large. Injection molding products market is vast, including electrical and electronic, automotive, cameras, watches, precision instruments, crates, containers, office machinery, building materials, medical equipment, toys, sports equipment, household sundries and so on. Because of its widespread use, it can be said that the economy is less of a particular industry or not affected. Look at the production of nearly 20 years of vertical injection molding machine, in addition to 1974 and 1975 after the oil crisis of 1973, the development is relatively stable. But in recent years, the proportion of needs of electronic, electrical, automotive injection molded products in three areas of the rapid increase in the three areas of the economy will affect the demand or not vertical injection molding machine. The data in Table 1 shows a few years after 1984 the high level of vertical injection molding machine production development, mainly supported by the results of these three industries. 1988 Japanese vertical injection molding machine production 14,633 units, far exceeding the Federal Republic of Germany in 5000 (estimate), 2016 sets the number of American, the reason lies in the rapid development of three major industries.
         4 Japanese plastic vertical injection molding machine domestic demand trends
         World production industry on the Japanese home appliances, steam. Cars and a large percentage of machine tools, the proportion of exports are correspondingly high. However, the proportion of exports vertical injection molding machine, in 1986 24.7% 1987 26.9% 1988 23.6%, is lower. Export some number of units (where export statistics only new equipment, such as including used equipment, including a high proportion in 1988 the export of second-hand equipment Taichung 5603, nearly 2,000 units of used equipment).
         Japanese production of vertical injection molding machine mostly in Japan, domestic use, which can be estimated Japan's injection molding industry;'s regulatory touch. Federal Republic of Germany produced less than half the number of vertical injection molding machine in Japan, but exports account for about 70 percent.
         Require vertical injection molding machine, although in the short term will vary with changes in climate conditions Qian, but look at the macro development will be smooth. With Japan in the automotive, electrical and other industries to increase as the center of the transfer abroad, vertical local supply may increase the injection molding machine. But Japanese companies generally use high technical reliability vertical injection molding machine made ​​in Japan, therefore, the current impact of offshoring is not large.
         In recent years, the growth of high-performance engineering plastic material production faster, with a corresponding demand for such vertical injection molding machine has also increased, and that the new level of grades of resin, engineering plastics should angle range is also rapidly expanding in this area demand will increase.
         5 plastic machinery development
         Ceramics, metal powder molding, new plastic material is completely different from the past, but also the use of injection molding, visible vertical injection molding machine for future applications will continue to expand. Thus, a single from plastic products industry trends need to estimate the vertical injection molding machine to die, because it is used for ceramics, metal processing industries.
         Vertical injection molding machine to make several domestic tanks have not been any investigation, however, the number of production units from the past, into the corpse number of units, the number of export units, units are estimated to be about life about 70,000 hours. Thus, since the first Bi fold melon purchase new machines to be safe, it is estimated more than 7,000 per year, plus performance due to technical backwardness Governor Wan hurried change machines in even greater need surgery.
         Japanese tax law, vertical injection molding machine life span of eight years. But in fact the use of time in more than eight years there, less than five years to dig the elimination of the situation there, in 1988 survey showed that the depreciation of about 6.8 years.
         Calculating statutory useful life of eight years, is like boot 16 hours per tender `25 days per month, but the actual business 24 hours a day, the vast majority.
         In addition, technological advances vertical injection molding machine is very fast, if not the introduction of new models, it can not meet the precision, stable molding requirements. From high-speed molding, energy consumption viewpoint, the use of old equipment, competitiveness weakened, therefore, particularly in the field of soil precision molding process of plastic, the purchase of new equipment to replace old equipment is very common.
         Consider the boot time of Taga, due to technical circumstances earlier update aging equipment, these factors have accelerated depreciation so, with at least 9000 to 10,000 vertical injection molding machine per year.
         The economic downturn, will inhibit the renewal of equipment, so vertical injection molding machine industry to estimate the updated requirements of the cautious, the estimated annual requirement for 7000 to 8000. Or so. Thus, investment in new equipment and adding two outputs, namely annual requirement, vertical injection molding machine in recent years, even if the situation is not very good, production will also be maintained at the level of 12,000 units.
         Import and export of six vertical injection molding machine
         6.1 exported to Japan vertical injection molding machine exports, 1977 to 1983, about 2,000 units per year, in 1984 about the jump to 3000, 1985 to 3400 units, 1986 3900 1987 fly up to 5,500 units, followed by a little like peaked like, was a standstill, 198 units in 5603, with respect to the production of vertical injection molding machine, a lower proportion of exports: in 1988 28.1% 1981 28.2% 1982 26.0% 1983 24.5% 1984 22.3% 1985 26.8%, almost at the level of two percent remain dozen. However, in 1986 a sharp rise of 34.6%, 45.8% up to 198 years, 1988 was 38.6%.
         Japan's domestic economic situation is good, when the vertical injection molding machine production activity, the proportion of exports are usually reduced in 1983 to a mother that Peru exports is reflected in a lower proportion of such situations.
         From 1986 after the situation, in 1986 the need to reduce domestic and export surge, although domestic demand increased catch a few years after 1987, but the proportion of exports remains high, which is not seen in the previous case, the reason is because of the increased export of second-hand equipment .
         The said system in, although not listed separately exports of used equipment, but according to statistics of Japan Plastics Machinery Industry Association and other industry groups (new equipment only statistics) estimated that in 1984 the total number of units for the 3022 stand exports, which used equipment 450 stand accounted x 4 9%;. xg 85 years, the export total number of units 3403 units, which used equipment 750 units, accounting for 22.0%, in 1986 the total number of units 3932 export units, used equipment 1,090 units, accounting for 27.7% ; 1987 exports of 5517 units, 2080 units of second-hand equipment, accounting for 37.7%, in 2988 exports of 5,603 units, used equipment 2,150 units, accounting for 38.4%. Increase exports of used equipment has changed the domestic economy while exports decreased in the past situation. Industry statistics, only new equipment export statistics, the actual result is slightly different. Vertical injection molding machine exporter as shown in Table 2, throughout the world, but more for the United States and Southeast Asia, especially in China stand, Hong Kong, South Korea, Singapore, Thailand, China as much. Only those countries with national conditions vary widely, especially in China, 1985 abnormal growth, intense change. Exporter of used equipment, almost all Southeast Guang - which the largest Philippine imports of used equipment.
         Vertical injection molding machine market in Japan is first in Southeast Asia, then Europe and the United States. Although the price is higher, but the quality, superior performance, buyers are more, especially electronics, motors and other precision products industry, many countries use Japanese equipment. Vertical injection molding machine production Asian countries and regions South Korea, stand, Hong Kong, Singapore and other increasingly active. According to business surveys vertical injection molding machine imported from Japan ah hydraulic device, the total annual production of several of these Asian countries and regions is about 500 ~ 600 units. These vertical injection molding machine low price, only Japan shot injection molding machine 1/2 ~ i / 3.
         Only prices, Japan's vertical injection molding machine is completely lost competitiveness, precisely because of the reasons for such a market, a lot of hand made ​​in Japan did not prepare out in these countries and regions. In addition, Japanese manufacturers original equipment exports will be used in Japan to check renovated before. Recently, combined with the local manufacture of low-cost advantage, the used equipment shipped directly to the exporter at the local check renovated in order to prevent prices remain competitive second-hand equipment.
         Good used equipment performance in Japan, long life, there is a letter reputation. Asian countries and regions Bu manufacturing vertical injection molding machine due to low prices, and the recent technical standards to improve, so in the American market is also a considerable number of units put into operation. But the gap compared with the Japanese equipment is still quite large: in the exporting country will not pose a threat to Japan.
         6.2 Imported
         Imported vertical injection molding machine, and production units less. Table 3 shows the Japanese import boil injection molding states do not work seven is the case of L.
         Is the maximum number of units imported in 1984, but also 383 sets of two, compared with 1975 imports, in 1983, stand's steady rise in the number of 1988, compared with a sharp increase in domestic demand in Japan, the display relative decline. Number of units relative to production, import ratio: 1975 was 7.5%, in 1976 3.0% 1355 1.9% 1086 1.5% 1987, 12%, in 1985 1.4 percent. From the importing country, the absolute majority of the Federal Republic of Germany days, almost swept all imports, but in recent years has also increased imports from Southeast Asia, in 1988 the total number of units and imports from the Federal Republic of Germany is quite imports from South Korea and China stand.
         Federal Republic of Germany and other technologies from the higher level to reduce the country imports reason, one vertical injection molding machine is a special equipment for those countries with the characteristics of today can be mass-produced in Japan, and second, maintenance, service and geometric not on the Japanese manufacturer; third is to meet the diverse needs of users in terms of, not, and Japanese manufacturers.
         Japan's vertical injection molding machine market, many vendors huddled together, technological competition, price competition is fierce, so the manufacturers have to work hard in the service, users also try to give a little to meet the requirements, user requirements for the production of small juvenile developers can also take a positive attitude and cooperation. Foreign firms is not easy to do. Therefore, in terms of foreign manufacturers, Japan's vertical injection molding machine market is indeed difficult to break into the market.
